[[play]]**“We crossed through silence and traversed the void, yet we remain entangled in the cocoon of fate.”**
In the year 3271, Earth is no longer the blue paradise it once was.
Ecosystems have collapsed, cities lie in ruins, and the embers of civilization flicker amid the chaos.
Everything changed the moment the signal arrived.
A non-natural transmission from the depths of space shattered humanity’s solitude.
After long years of decoding and analysis, one truth became clear: we are not alone.
This is the era after the Great Filter—only those civilizations that survive technological peril, self-destruction, and external threats can step onto the stage of interstellar society.
There, alongside other alien civilizations, we discovered the **Cosmic Cube**—
an entity beyond the constructs of space and time, said to contain the power and truth to rule the universe.
But the desire for the Cube sparked centuries-long interstellar war.
Earth became a battlefield, its surface scorched and uninhabitable.
Humanity was forced underground, constructing a **three-layered cocooned ecosystem** to survive.
- **C-Layer**: The surface, ravaged by violent storms, became a place of exile for society’s lowest ranks.
- **B-Layer**: Between the crusts, a chaotic zone where order and anarchy coexist.
- **A-Layer**: Deep within the core, the heart of civilization, governed by selected intellects and leaders.
To curb escalating ambitions, the interstellar civilizations reached a consensus, forming the **Universal Alliance**, with each member world taking turns safeguarding the Cube.
Now, it is Earth’s turn—
this fractured, scarred planet must shoulder that responsibility.
In this new world, the social order has been redefined:
reason overrides emotion, hierarchy tramples equality.
But the truth is far more complex than it seems.
Every choice is a roll of the dice toward the future.
Not everyone will emerge alive from this labyrinth.
And not every encounter will lead to answers.
[[start the journey]]Earth appears to operate in an orderly fashion.
The storms of the C-Layer drown out the cries, the machines of the B-Layer devour resistance, and the sunlight in the A-Layer rises as always—
Everything seems meticulously organized, and the layers have long grown accustomed to ignoring one another in mutual silence.
You are an investigator, designation 0493-C, a “Non-Affiliate” selected from the C-Layer’s neutral class.
You're accustomed to roaming between the three layers—observing, analyzing, reporting—but never intervening.
This time, however, is different.
Recent surface storms have grown more violent than usual.
The “Pulse Valve Corridor” of the C-Layer—a vital power-circulating and transport network that connects all three layers—has begun to shut down unpredictably.
Your sensor data tells you: something is not right.
[[Report to A-Layer]]You decide to report to the A-Layer.
According to protocol, this should immediately grant you access to the upward transit channel.
But the channel refuses to respond—locked down, with no explanation.
You turn instead to the C-Layer’s elder leader, a woman named **Geya**—
a survivor from Earth’s early terraforming days, and one of the few who still remembers the “sky above the ground.”
She gazes at you for a long moment, then leaves you with only a single sentence:
**“When the wind blows, you don’t hear the wind itself—you only hear what it destroys.”**
She refuses to cooperate, ignoring your data reports entirely.
Meanwhile, a dire transmission arrives through the interstellar channel—
The alien civilization known as **Nyxshade** has breached the edge of space, launching attacks on Earth’s outer sentinel stations.
Fleets are assembling.
**War on Earth is about to begin.**
[[An emergency order]]Suddenly, you receive an emergency order from the A-Layer High Command:
**"Designation 0493-C, initiate Operation *Skyblade*. You are granted temporary full command authority. You are to act as Earth's representative in declaring war on the alien civilization 'Nyxshade'."**
**"No need to await interstellar authorization. Action begins immediately."**
But at the very same moment, Elder Geya from the C-Layer reaches out to you in a secret message:
**"If you ignite this war, the storm will consume us all. Please remember—we are not weapons. We are human."**
You now stand at the fracture point.
On one side, a devastating preemptive strike.
On the other, the faint will to survive of the powerless.
And deep down, you know—
Earth’s balance is already crumbling.
The alien invasion may not be the cause... but the consequence.
[[You press the execution key. Operation Skyblade begins.]]
[[You refuse Operation Skyblade.]](track: 'my_music', 'stop')

}
In the night sky over the C-Layer, it was no longer lightning from the storms that streaked above—
but orbital firepower descending from the heavens.
Blinding white light tore through the clouds—
and tore apart everything you once knew.
You had believed it would be a show of force, a calculated warning strike.
But you underestimated how the A-Layer defines “acceptable sacrifice.”
Within seven hours, the entire C-Layer collapsed.
Shelters crumbled, environmental systems were forcibly shut down, and hundreds of thousands of civilians were lost to aftershocks and rubble.
You crawl through the ruins, surrounded by cries for help.
The system alarms have failed, and you feel like a leftover trace of data from this “operation”—
unarchived, unanswered.
[[Sudden]]Just as you were on the verge of losing consciousness, a burst of light shattered the sky and pulled you from the collapsed ruins.
You opened your eyes—and saw him.
**Sigma**, from the A-Layer.
The one known as “Earth’s Last Shield.”
He is a hero, a chosen figure.
You recognize him—and he recognizes you.
But he doesn’t accuse you. Instead, he speaks in a low, steady voice:
**“Did you see them? The structures growing in the crust—those things don’t belong to Earth. This war... is hiding something much deeper.”**
Sigma is an unofficial operative, unregistered in the system, sent by the A-Layer.
He infiltrated the C-Layer because he sensed a greater, more ancient force at work behind this conflict—something encroaching, something alien.
You retreat together—but it’s too late to change the course of war.
**The C-Layer has fallen.**
Together, you and Sigma break through the lockdown and descend into the depths of the **B-Layer**—
a molten city of the damned, the fugitives, and the forgotten.
The power here flickers, the systems are broken—
yet some faint traces of human warmth and order still remain.
[[The B-Layer]]The B-Layer is not hell—
but it’s no longer part of the human world either.
It is a nest woven from those forgotten by the system,
a fault-line zone where violence and brilliance conspire.
You move through the mist of this city of scrap and steel,
holding a black market crystal chip in your hand—
its data encoded with anonymous intel from the **Northern Outpost**.
During your exploration of the B-Layer,
you and Sigma uncover an ancient **Core Ruin**—
a structure not built by human hands,
buried deep beneath the Earth long before its terraformation.
Inscribed on its surface is a **construct language**,
identical in origin to that of the **Cosmic Cube**.
**“If we can unlock the secrets of the Cube,”**
**Sigma says, “then maybe… just maybe, we can still save this planet.”**
[[Unearth the Truth within the B-Layer.]]Sigma throws down a geo-construct schematic, decrypted using high-level A-Layer access. He points to a shielded signal source deep within the Earth’s core:
**"We’re running out of time. They’ve already begun relocating the core structure."**
You and Sigma begin working together to unearth the truth within the B-Layer.
He uses a forbidden A-Layer logic algorithm to crack what remains of the Central Archive,
while you trade hushed words and credits with loose-lipped bounty runners in the black alleys of the lower district,
gathering fragments of intel.
Piece by piece, a larger picture emerges:
**“The A-Layer elites have long known the Cosmic Cube is behaving abnormally.
But instead of destroying it… they chose to control it.”**
On the eve of the alien invasion, they secretly relocated the Cube into a secure structure,
disguising the operation as a “crustal quake.”
In the process, they shut down most upward access routes.
But what they never sealed off—was the **downward path**.
From the A-Layer’s heights to the B and C Layers below,
from civilization’s pinnacle into the dark well of dust and ash—
that descent was always left open.
**They do not fear chaos.
They fear your questions.**
Meanwhile, Sigma uncovers a staggering secret in a damaged Keplerian transmission log:
**“The so-called ‘Keplerian mastery of the Cube’... was a lie.”**
**“Their homeworld collapsed in civil conflict. But their fabled victory became the spark for interstellar war.”**
This lie—this **myth of a false god**—became the most powerful deterrent in the galaxy.
A fabricated divinity that maintained a fragile, unstable peace for decades.
But now, Earth’s term as custodian of the Cube is nearing its end.
Alien civilizations are amassing at the borders, demanding **handover rights**.
The A-Layer refuses.
They will not relinquish the Cube.
They will not give up their claim to becoming a **candidate god**.
So they chose **war**—to bury the truth.
Sigma speaks, his voice heavy:
**"They don’t want to protect humanity.
They want to replace the gods."**
You both stand before a long-abandoned ascension core,
gazing upward toward the A-Layer, thousands of meters above.
Up there, the lights dazzle—yet there are no stars.
Down here, shadows loom—but flickers of fire still survive.
In that moment, you both understand:
**Not all wars are meant for destruction.
Some are fought so truth may be reborn.**
[[You fall into deep thought.]]You’ve always felt that the problem lies beyond the stars.
You discover that the Earth’s systems had already begun to fracture long before the alien invasion,
and the A-Layer elites are desperately trying to conceal the truth.
Meanwhile, factions within the B-Layer quietly gather, preparing to resist the alien forces by any means—even if it means mutual destruction.
The access routes to the A-Layer are sealed tight, defenses formidable.
In this moment of crisis, you choose to draw the guards away yourself,
giving Sigma the chance to survive.
**“You have to get through. We all need answers.”**
Sigma rushes into the passage as you fall amidst fire and shockwaves.
[[Things have taken a turn for the better.]]But fate did not end you—
you were rescued by a resistance group hidden deep within the B-Layer.
Those who have been mistrusted have already begun to act.
When you awaken, you find yourself in the underground base of the B-Layer resistance.
Their leader presents you with two choices:
1. Stay and help the resistance prepare for an all-out war,
rebuilding order from the bottom up;
2. Use the “Pulse Valve Passage” they recently blasted open,
a direct route to the A-Layer, to uncover the core truth.
After a moment of silence, he looks toward the still-smoking passage—
the gateway to the Earth’s core, finally reopened once more.
[[You decide to stay in the B-Layer.]]
[[Delve deeper into A-Layer.]](track: 'my_music002', 'stop')
(track: 'my_music003', 'play')
{
(track: 'my_music003', 'loop', true)
(track: 'my_music003', 'playwhenpossible')
}
You decide to stay in the B-Layer, joining the core faction of the resistance.
In this dark, smoke-filled underground base, you face a new dilemma:
Will you unite the forces of the B-Layer to confront the ever-advancing alien civilization,
defending the Earth’s final line of defense?
Or will you launch a full-scale uprising, striking directly at the corrupt A-Layer elites,
exposing the conspiracy behind their power, and fighting for true freedom and the future?
Both paths are fraught with trials of blood and fire.
Every decision will reshape the fate of Earth.
[[Rebel against the alien civilization]]
[[Wage war on the A-Layer]]You lead the forces of the B-Layer in a relentless all-out assault against the alien civilization.
Their weapons rain down like a furious storm, their morale soaring—they are determined to defend their last home.
Yet the enemy’s technology far exceeds all expectations;
their defenses are impenetrable, and their counterattacks swift and merciless.
Charge after charge is shattered, communications cut off, reinforcements unreachable.
The truth remains hidden deep within the fog—you cannot uncover the secrets behind it all.
In the end, Earth fractures amid roaring flames;
its once-great civilization reduced to ashes.
The sky darkens, stars fall, and the former home is utterly destroyed.
BAD ENDDINGYou lead the rebels storming into the A-Layer’s core control zone, reaching the so-called “Zero Space.”
It is said that here lies the Universe Cube—an artifact capable of altering the fate of the cosmos.
But as the complex mechanisms of “Zero Space” activate,
what unfolds before your eyes is an empty chamber.
No Cube, no energy fluctuations, not even a trace of data logs.
The highest leader of the A-Layer approaches silently.
Facing your burning fury, he speaks slowly:
“The Cube hasn’t been here for a long time.
In fact, it never truly belonged to us.”
[[the Harsh Truth]]As the conversation deepens, you finally piece together the harsh truth:
Earth’s collapse was not caused by an alien invasion, but by deep divisions within its own social hierarchy.
The three layers of society are severed from one another,
with resources, power, and hope increasingly concentrated at the top,
while the lower layers fall into deeper despair.
The pulse channels connecting each layer gradually close,
the social structure stiffens, and civilization loses its vitality.
B-Layer was the first to perceive this and led the rebellion.
The A-Layer elite, desperate to maintain control, sought to unlock the Cube’s secrets, hoping to gain power to reverse everything.
But they themselves couldn’t decipher it, so they “deliberately” planted the Cube’s secret in the C-Layer,
secretly leaking information to the outside world,
drawing alien attention and pressure,
turning the C-Layer into a testing ground to see if the Cube could be activated.
And Sigma—the so-called “hero” from the A-Layer—has actually been tasked with monitoring the Cube’s status, evaluating the reactions of each layer, and reporting intelligence back to the A-Layer.
You are stunned.
You thought you were resisting injustice and seeking the truth.
But everything has been orchestrated.
And the “Cube” may just be a façade.
The real problem has never left Earth’s core.
[[The Truth]](track: 'my_music003', 'stop')
(track: 'my_musicend', 'play')
{
(track: 'my_musicend', 'loop', true)
(track: 'my_musicend', 'playwhenpossible')
}
The truth cuts through the fog like a sharp blade.
You finally understand that all the chaos, war, and destruction did not come from alien enemies—but from humanity’s own divisions and ambitions.
You decide to go to the surface and reveal the truth to everyone.
“The enemy of humanity has never been beyond the stars—it has always been ourselves.”
You plan to broadcast this message, to awaken those with conscience still left in C-Layer, B-Layer, and even A-Layer.
You step onto the last emergency elevator track leading to C-Layer, your eyes burning with resolve.
But when you arrive at the channel exit, it is already too late.
The alien fleet has broken through the defenses, flooding into the core area of A-Layer like a raging tide.
The defense systems fail, the ecological dome shatters, and gravity and energy systems collapse in an instant.
Flames engulf the city, piercing screams tear through the dome, and the earth tears apart in violent tremors.
Only you remain, standing at the edge of the ruins, watching the collapsing light tower and the crumbling city.
You finally understand: the truth cannot save a world that has lost the ability to listen.
In the last flash of light, you slowly close your eyes, as if still hearing that unheard message echoing in your ears—
“We could have lived differently.”

(track: 'my_music004', 'playwhenpossible')
}
You stand before the command terminal, staring at the red-glowing button labeled “Skyedge” — the codename for Earth’s high-energy orbital weapon system. Once activated, it would signify Earth’s official declaration of war against the alien civilization.
Your finger hovers for a long moment, but in the end, you slowly withdraw it.
You know that once you press the button, there’s no turning back.
Instead, you choose a different path — negotiation.
Amidst the extreme tension, you send a contact request through an old interstellar channel to the invaders, using the identity “Observer 0493-C,” asking to enter neutral talks.
At first, there is no response. Hours later, a cold but polite reply arrives:
“Who are you? Who do you represent? Human society no longer has a unified will.”
You pause briefly, then respond:
“I cannot represent all humanity, but I can speak for the rational minds still remaining.”
This brief exchange becomes a breakthrough. Thanks to your persistence, they finally send a diplomatic AI to meet Earth’s civilization in a virtual conference room.
[[Negotiate]](track: 'my_music002', 'stop')
(track: 'my_music003', 'play')
{
(track: 'my_music003', 'loop', true)
(track: 'my_music003', 'playwhenpossible')
}
The underground explosions roared like a great beast, shaking the entire crust with a faint tremor.
The B-layer resistance no longer waited for diplomacy or tried negotiations. They unleashed their last resources to blast open the “Pulse Vein Passage” to A-layer — a once-sealed energy conduit that hadn’t been used for years. Now reopened, scorching energy raged through the pipes.
The B-layer leader looked at the passage forged of fire and steel and handed you a sealed suit of armor.
“We’re betting you can find the truth.”
You nodded with calm resolve. Passing through the scorching Pulse Vein track, you entered the legendary “City of the Gods” — A-layer.
There, it was still resplendent and magnificent, the ecology perfect, and order impeccable, as if the turmoil outside had no connection to this place.
But the more serene it seemed, the more you sensed a chilling illusion.
You understood that the real answers were hidden beneath this façade. This time, you were no longer a mere reporter, but a seeker.
[[The A-Layer]]As you passed through the scorching conduit and stepped into A-layer, everything before you clashed with the perfect “utopia” you remembered.
The place was still pristine, orderly, and flawlessly white; the air crisp as an early spring morning, the city suspended between a web of blue and white light.
But the closer you got, the more you felt a suffocating stillness —
The orderly crowds on the streets moved in unison, their eyes vacant, as if running on mechanical autopilot;
No one spoke, no one looked back, the city was silent like a hollow shell of metal.
You ventured into the “low-function zone” of the city and were shocked to find a group of thinly clad, hollow-eyed people gathered there.
They were maintaining energy cores, cleaning sewage pipes, and sweeping ventilation shafts — tasks that should have been handled by automated systems, now replaced by human labor.
You approached one worker and froze — it was an old man you had seen before in C-layer.
“You… why are you here?”
The old man didn’t respond, mechanically repeating his task, a brand stamped on his forehead: “Adjuster.”
Someone nearby whispered that these people were “selected” elites from C-layer, originally believing they could change their fate,
but after having their identities, wills, and ability to express themselves stripped away, they were reprogrammed into the system as “managed labor.”
Inside A-layer, a quiet split had already taken place:
The upper tier still sat at the center of power, controlling all resources;
While the “new residents” in the lower tier had long lost autonomy, reduced to mere laborers.
You finally realized: this “utopia” had long since lost control.
It was no longer the pinnacle of an ideal society, but the highest form of oppression — a hotbed of desire.
The true collapse had already begun at the moment it became invisible on the surface.
[[the "Zero Space"]]You arrive at the "Zero Space," the storage chamber said to contain the Cosmic Cube capable of altering the fate of the universe.
But when the heavy mechanisms of Zero Space unlock, what unfolds before your eyes is an empty, hollow chamber.
No Cube, no energy fluctuations, not even a trace of data records.
The highest leader of A-layer approaches quietly. Facing your burning anger, he slowly speaks:
“The Cube hasn’t been here for a long time. In fact, it never truly belonged to us.”
[[Obtained the truth]]

{
(track: 'my_musicend', 'loop', true)
(track: 'my_musicend', 'playwhenpossible')
}
As the conversation deepens, you finally piece together the harsh truth:
Earth’s collapse was not caused by an alien invasion, but stemmed from a profound internal division within its hierarchical layers.
The three-tiered society is fractured; resources, power, and hope are increasingly concentrated at the top, while the bottom grows ever more desperate.
The vital pulse channels connecting each layer are gradually closing, social structures stiffen, and civilization loses its vitality.
The B-layer was the first to perceive this and launched the initial rebellion.
The A-layer elites, desperate to maintain control, sought to unlock the secrets of the Cube, hoping to gain the power to reverse everything.
Unable to crack it themselves, they deliberately “secretly” placed the Cube in the C-layer, spreading rumors to the outside world,
drawing the attention and pressure of alien civilizations, and using the C-layer as a testing ground to see if the Cube could be activated.
And Sigma — the so-called “hero” from A-layer — was actually tasked with monitoring the Cube’s status, evaluating reactions across the layers, and reporting intelligence back to A-layer.
You stand frozen.
You thought you were resisting injustice and seeking truth, but everything had been guided all along.
And the “Cube” might just be a distraction. The real problem has never left Earth’s internal depths.
[[The disaster]]The disaster came without warning—yet it had long been inevitable.
Shortly after you uncovered the truth about the A-layer, the alien civilization known as the “Nightmare” launched a full-scale assault.
They did not come to plunder, but because the location of the “Cosmic Cube” was exposed, and Earth had lost the right to guard its secret.
Shockwaves tore through the dome like thunder; the A-layer’s defense systems were powerless against their precise strikes.
One aerial fortress after another collapsed; the orbital defense lines lost power support, and cities crumbled like avalanches.
The B-layer fought desperately, with rebels trying to protect the last remaining passages before the apocalypse.
Meanwhile, the A-layer power centers had already fallen into chaos—some attempted to flee, some tried to surrender, and others still believed survival could be negotiated.
The C-layer was helpless to resist, becoming the first land sacrificed amid the chaos.
And the Cube—the symbol of “universal dominion secrets”—was ultimately taken away by an unidentified fleet.
No one knows where it was taken—whether entrusted to another civilization or sealed away forever.
Earth disintegrated amid a conflagration of light and fire.
The blue planet that nurtured civilization for millennia now drifts as silent ruins amid the cosmic dust.
In the final record, only one line was transmitted—
“We did not lose to an external enemy; we lost to ourselves.”
BAD ENDDINGThe leader of Layer C, Ren Ge Ya, represented Earth’s civilization in the communication with the alien civilization. No one knows exactly what transpired during those negotiations. However, the outcome was a temporary ceasefire, with the interstellar fleet standing silently on standby. Yet this calm was nothing more than the quiet before the storm.
[[Gather Information]]On the chaotic fringes of the surface, you rush around gathering information, trying to pierce through the increasingly sealed communication and transport channels between the layers of the Cocoon. But because you refused to activate the "Sky Edge" weapon as demanded by the A-layer leadership, your authority was revoked, all upward channels were blocked, and even the most basic distress signals fell into silence.
During one long and desperate patrol, you encounter a suddenly appearing stranger—his expression stern, his gaze sharp. He is the "hero" from A-layer, Sigma.
He does not introduce himself but simply says, "You are Investigator 0493-C, right? I know about the anomalies you’ve detected. Now, Earth’s time is running out."
You watch him warily. "You’re from A-layer… how are you here?"
Sigma’s eyes gaze toward the desolate remnants of the C-layer sky dome, his voice low: "I suspect there’s a problem at Earth’s core. The pulse conduit to the core is closing. Earth’s imbalance is accelerating."
He pauses, then continues: "Worse still, we are in the custody period of the Cosmic Cube. Alien civilizations are watching closely. If we show signs of decay at this moment, the Cube will be considered 'abandoned property' by the Alliance rules, and they can forcibly reclaim it."
[[You furrow your brow. "So that’s why you came to C-layer?"]]You furrow your brow. "So that’s why you came to C-layer?"
Sigma nods. "I’m here to verify the Cube’s status and find a way into the Earth’s core. According to the latest intelligence, the Cube is now hidden in the core’s ‘Zero Space.’ We must unlock its secrets—Earth will either be saved or destroyed by it."
With Sigma’s help, you both avoid the collapsed official passages and chaotic checkpoints, passing abandoned cooling towers, wasteland transport cables, and deep well hangars. Along a long-dormant emergency maintenance track, you infiltrate B-layer.
There, you find another kind of hell.
But your journey is only just beginning.
[[B-layer is neither hell nor the realm of the living.]]It is a tangled den of those forgotten by the system—a fissure where violence and cunning conspire.
You move through the fog of the Scrap Iron City, holding a black-market crystal chip that contains anonymous intelligence from the “Northern Axis Contact Point.”
During your exploration of B-layer, you discover an ancient “Relic Core.”
It is a non-human constructed structure, seemingly buried long before Earth’s terraforming.
On the relic’s surface appears a “construct language” sharing the same origin as the Cosmic Cube.
You finally realize that the collapse of Earth’s ecosystem was not caused by war, but is a sign of the Cube’s corruption.
The true enemy may have never fully revealed itself.
“If we can unravel the Cube’s secrets, perhaps... we can still save this planet.”
— Sigma
[[dig into the truth in B-layer.]]Sigma throws down a geo-structural map cracked using A-layer clearance, pointing deep into the Earth’s core to a signal source that has been shielded:
“We don’t have much time. They’ve already begun relocating the core structure.”
You and Sigma join forces to dig into the truth in B-layer.
He uses a disabled A-layer logic algorithm to hack into the remnants of the Central Records Bureau database, while you trade with loose-tongued bounty dealers in the dark alleys of the lower city to gather fragmented intelligence.
Bit by bit, you piece together the full picture:
“The A-layer elite already knew about the Cube’s anomaly. They decided not to destroy it, but to control it.”
On the eve of the alien invasion, A-layer secretly transferred the Cube to a secure structure and disguised it as a “tectonic quake,” shutting down most upward access paths.
But the “downward” path — from A-layer falling into B-layer and C-layer, from the pinnacle of civilization into the deep wells of dust — was never closed. That path remained wide open.
They fear not losing control, but that you might question them.
Meanwhile, Sigma uncovered a shocking secret from a damaged Kepler civilization comm log:
“The so-called ‘Kepler civilization successfully cracked the Cube’ is a lie.”
“Their homeworld self-destructed in internal conflict, but their false victory became the fuse that ignited the cosmic war.”
This lie became the universe’s strongest deterrent. A false “god” kept interstellar society in unstable peace for decades.
But now, Earth’s tenure as Cube custodian is about to expire. Alien civilizations gather at the borders, demanding “handover rights.”
A-layer refuses to relinquish the Cube, unwilling to lose its status as “candidate for the supreme deity.”
So they choose war—to cover the truth.
Sigma’s voice is low and grim: “They don’t want to protect humanity. They want to replace the gods.”
You stand before a long-abandoned elevator core in B-layer, looking up toward A-layer thousands of meters above.
There, lights glitter, but no stars shine;
Where you stand, darkness spreads, yet the spark still burns.
In this moment, you understand:
Not all wars are about destruction. Some wars exist to let truth be reborn.
[[About Sigma]]As you traverse the ruins of B-layer’s urban zones, Sigma always leads the way. He speaks little and never offers many explanations, but every turn and shortcut feels like second nature to him. He knows the B-layer map intimately—astonishingly aware even of the “patrol schedules” in certain areas.
Along the way, you encounter an old mechanic sitting by the roadside. He pauses, staring at Sigma as if recalling something, then whispers, “Do you remember the old warehouse? That year you—”
Sigma smiles faintly and gently interrupts, “Now is not the time for memories.”
There’s no impatience or deliberate avoidance in his tone, but his pace quickens slightly, as if eager to leave.
One night, resting at a temporary shelter, a young volunteer delivers supplies to you. The boy is thin, face smudged with dirt, but his voice carries deep respect: “I’ve heard of you… you came from A-layer. To come here, it’s really…”
Sigma only nods, offering no praise in return, simply saying, “Thank you for the supplies.” Then he turns to check his communication devices, seemingly too accustomed to such words, calmly handling them with practiced ease.
When he mentions the Cube, his tone remains steady, but you notice that his meticulous planning of routes, precise timing, and relentless drive forward all sharpen at that moment—not with excitement or zeal, but with unwavering, exact focus.
He neither makes mistakes nor does anything unnecessary.
He helps you enter B-layer, secure resources, and steadily advance the mission—each step unfolding as if long preordained.
You ponder this when Sigma suddenly stops leading ahead, turns to you, and asks, “Earth is on the brink of disaster. Will you be my partner, and help save it all?”
[[You trust Sigma and walk alongside him.]]
[[You don’t believe Sigma’s words.]]
[[Although you harbor doubts, you still agree.]](track: 'my_music004', 'stop')

You and Sigma trek deep into the heart of Layer B. You had believed this to be a stronghold resisting the alien invasion, but what you saw was something else entirely.
The streets of Layer B were strewn with rubble and ruins. Factories roared nonstop day and night, while the people looked gaunt and worn, as if they had become mere cogs in the war machine. It turned out that the so-called “resistance war” was not a unanimous cause, but rather a power gamble launched by Layer B’s leaders. They exploited long-standing grievances against Layer A’s oppression, stirred up public sentiment, forcibly requisitioned resources, and even sacrificed the livelihoods of the lower classes to keep the war machine running.
You fell into silence for a long time. You had once believed Layer B to be the beacon of freedom and justice, but now you saw a different, extreme form of chaos. You realized that if the unrest continued unchecked, the entire Earth would fall into irreversible imbalance, and the three-layer social structure would collapse.
So, after a secret discussion with Sigma, the two of you made a difficult decision: to head to Layer A, cooperate with its leaders, and temporarily stabilize the situation to contain the Layer B uprising. Although this was not the choice everyone hoped for, only by stopping the chaos could there be any chance to truly start rebuilding. You called this your “postponed hope”—first stop the bleeding, then begin the healing.

The journey into Layer A proved far more arduous than you and Sigma had anticipated. The pulse vein tunnels leading to the Earth’s core were riddled with blockades, detection systems, and unknown interference signals—as if the entire planetary core was warning against their approach.
Once comrades side by side, you and Sigma clashed at a blockade node. Sigma insisted on forcing through, confident that his authority and status could clear the way. You, however, sensed abnormal energy fluctuations and judged the path to be impassable. After a tense disagreement, silence fell between you both, and ultimately, you parted ways by mutual understanding. Sigma took an alternate route through the high-voltage grid lines toward Layer A, while you remained in Layer B, waiting for the right moment.
During this time, you delved deep into the heart of Layer B’s urban core, connecting with more of the “lost.” You learned that most low-level migrants who had entered Layer A had vanished without a trace; rumors surrounding the “Cube” grew increasingly chaotic; and it seemed Layer A had already initiated a “silent plan” targeting the lower worlds.
Layer B began to boil. The underground network linked up, and some radicals openly declared that they “could no longer wait.” Finally, during an operation codenamed “The Knocker,” the people of Layer B used high-frequency oscillation devices to physically destroy parts of the blockade nodes, forcibly opening the pulse vein tunnels to Layer A.
At the moment the passage opened, you stood calmly before the reactivated core elevator. You knew you might soon confront the most intricate web of lies Earth had ever known. But this time, you would wait for no permission, expect no companion.
You took that step forward and embarked alone on the journey to Layer A.

You and Sigma entered Layer B together, and the sight before you left you stunned—riots were spreading, the streets swarmed with fleeing crowds, and from beneath the crumbling ruins came faint cries for help and moans of pain. Refugees huddled together in helplessness, the wounded groaned in agony, and the air was thick with chaos and fear.
Yet Sigma, standing beside you, looked on with cold, steady eyes. His expression was calm, showing not a trace of pity for the suffering before him. He spoke quietly, “This storm is necessary. Only through conflict can order be rebuilt.”
You stared at the devastation and helplessness around you, and a faint doubt began to rise in your heart—was this man, hailed as a philanthropist and revered as a savior across the layers, truly as benevolent as the stories claimed? Was his indifference the result of hard choices—or was there something darker beneath it? That question began to take root deep within you.
[[step into Layer A]]On the journey to Layer A, you gradually learn the true background of the hero Sigma — he was not born into the noble class of Layer A, but grew up in the most barren region of Layer B. Even as a boy, he showed exceptional intelligence and unwavering will. Through a rigorous selection process, he broke through the barriers of the social hierarchy and eventually entered Layer A, becoming an important member of the ruling class.
Sigma’s story has been crafted by Layer A as a symbol of social mobility. His journey is told throughout the three layers, inspiring countless people trapped in hardship. He is the embodiment of systemic justice, the direction for the people of Layer B’s struggle, and the light that children in Layer C look up to.
You do not doubt the authenticity of this history; rather, you hold deep respect for Sigma’s experience. You believe that because Sigma once intimately understood the suffering of the lower layers, he is better able to grasp the essence of class conflict and is more likely to become the key figure who can break Earth’s chains of fate.
Therefore, when Layer B falls into turmoil, you do not hesitate to stand alongside Sigma and head to Layer A together. You believe that only by leveraging Sigma’s influence and your combined strength can the internal chaos be quelled, order restored, and a sliver of hope secured for the greater crisis looming ahead.
[[Inside Zero Space]]Under Sigma’s lead, you passed through layer after layer of defenses and finally reached the core ruling center of Layer A—the forbidden zone known as the “Zero Space.” Here lay one of Earth civilization’s most mysterious and dangerous artifacts: the Cosmic Cube.
Inside Zero Space, time seemed to freeze. The moment you stepped in, you felt an intense sense of distortion. What surprised you even more was how exceptionally familiar Sigma appeared with everything here. He expertly operated the permission terminals, unlocked the defense systems, and even guided you accurately through the complex protective layers. You showed no doubt outwardly, but quietly took note of this unusual familiarity.
At the deepest part of Zero Space, you saw the true Cosmic Cube—not the “symbolic objects” that had been rotated through the layers before, but the real cosmic relic, radiating strange energy. At this moment, the hero revealed a shocking truth:
To maintain their rule over Layer A, the leaders had long manufactured several fake cubes to “rotate” outwardly, secretly hiding the real Cosmic Cube for covert research, hoping to unlock its power.
However, during the research, they underestimated the Cube’s reaction mechanisms. A deep analysis accidentally triggered its defense system, releasing a special electromagnetic wave that was immediately detected by the Galactic Alliance’s surveillance. Earth was thus exposed, triggering intense alarm and siege from alien civilizations—they suspected Earth was attempting to unilaterally control the Cosmic Cube and upset the existing balance.
Standing before the Cube, you felt unprecedented pressure. A question began to surface in your mind—why was Sigma so familiar with Zero Space? Was it simply trusted authority bestowed upon him, or... was there a deeper secret connection? This doubt, like the uneasy energy within Zero Space, was impossible to resolve for now.
[[your faith wavers]]After learning the truth that the Cosmic Cube incident triggered the alien civilizations’ siege, your faith wavers. You realize that the crisis facing Earth is not the result of the uprising in Layer B, but the consequence of Layer A’s attempt to monopolize power.
Sigma falls silent for a moment before speaking slowly. He admits that he once firmly believed in Layer A’s system, thinking that stabilizing the ruling order would bring peace and prosperity. But after personally stepping into Layer B, he saw how the world he once belonged to was now stripped and oppressed. He could no longer serve as a symbol of the “model citizen” for a system destined to collapse.
Persuaded by Sigma, the investigator finally makes a choice. They no longer serve Layer A’s interests, but decide to jointly spark a true transformation. Using Sigma’s accumulated influence within Layer A, you secretly reach out to scientists, administrators, and grassroots stability enforcers who harbor doubts, gathering a group eager for change.
This is not a reckless rebellion, but a battle of wisdom and conviction. You seek not only to overthrow the old regime, but to rebuild Earth’s order—allowing the three layers to truly communicate and coexist.
At the heart of it all remains the silent yet undeniable Cosmic Cube. It is both the source of chaos and a symbol of hope. Overthrowing the old order is only the beginning. The real challenge lies in how to build a future where Earth will no longer collapse.
[[The rebellion in Layer B]]The rebellion in Layer B spread like wildfire, eventually reaching the towering walls of Layer A. The long-dormant tremors from the Earth’s core awakened the sleeping utopia, and all of this seemed to confirm the collapse Sigma had long foreseen.
Faced with the surging warriors from Layer B, Sigma chose not to revert to his role as a guardian of Layer A. Instead, he turned and shook hands with the leaders of Layer B, declaring a joint resistance against the decayed power center. This decision moved you deeply and prompted many hesitant civilians in Layer A to rethink the boundaries between “security” and “freedom.”
However, just as the alliance was taking shape, you and Sigma ventured deep into Layer A’s heartland, visiting those who had been “promoted” from Layers B and C. What you discovered was an unsettling truth.
They hadn’t become the elites as rumors suggested. Instead, they were placed in massive labor centers, performing the most tedious and repetitive tasks. Some had long since lost expression and operated like machines; others had even grown slow to speak. Layer A was no longer a symbol of hope but more like a psychological prison elegantly disguised.
You felt a deep discomfort. The path “upwards” was not a passage to freedom, but a predetermined track of fate. When “hope” itself has been co-opted by the system as a tool of control, what is truly worth believing in?
Sigma remained silent on this, only watching these quiet “cogs” with a complex light in his eyes. Perhaps more than anyone, he understood that cracks had long spread through every inch of this ivory tower.
[[The truth gradually emerged.]] The collapse of Earth was never the result of an alien conspiracy, but stemmed from internal structural decay. The flow between social strata grew increasingly restricted; the passages from Layer C to Layer A were slowly sealed off. The entire society became like a machine freezing over—beneath the noisy surface lay dullness and rot.
Layer B was the first to sense the crisis. They weren’t seeking “invasion,” but survival, striving to break the chains blocking their path of destiny. They planned to use the existence of the Cube to shake Layer A’s authority and release a signal powerful enough to disrupt the established order.
And that figure known as the “hero” Sigma—the one cloaked in glory and celebrated as a savior—he was neither a traitor nor a messiah. His mission was always that of an observer. Tasked by Layer A, his sole duty was to monitor how the Cube affected each layer and faithfully report the changes across the strata, providing decision-makers with insight to determine the future.
The hero never intervened—he only watched.
And now, you finally understand: this civilization’s experiment was never about the Cube itself, but whether we still remember the bonds that ought to exist between us.
[[Negotiations broke down]]Negotiations between Layer C and the alien civilization ultimately broke down. Alarms blared at the city’s edge, and an unnatural blue light spread across the sky—signaling that enemy ships were about to breach the orbital defenses. The surface residents, barely recovering from the ashes of civil war, now faced an even harsher, catastrophic threat.
[[Together with Sigma and the people of Layer B, you overthrew the rule of Layer A.]]As the flames of war approached and the temporary joint defense lines of Earth’s three layers were established, Hero Sigma’s influence reached an unprecedented peak. He led the people of all layers to unite, allocate resources, mobilize technology, build defenses, and rebuild trust. People began to stop judging each other by their origins and instead placed their hope in this “hero” who once came from Layer B and now led the entire planet’s resistance.
At the final pre-war meeting, everyone unanimously elected the hero as the new leader of Earth, entrusted with overseeing the planet’s fate and reshaping the order of the three-layered world.
At that moment, you quietly stand behind the crowd, watching the hero under the spotlight. He recalls the truths and lies, sacrifices and betrayals along the way, and also remembers Sigma’s unsettlingly calm familiarity in the Zero Space. You know this hero holds the power to change the world—and perhaps the power to control it.
The world awaits his choice.
— Do you support Hero Sigma becoming the new ruler?
This choice is not just a transfer of power, but a crossroads leading to the future.
[[You ultimately chose to support Hero Sigma.]]
[[You refused to continue helping Sigma and left him.]]Under Sigma’s leadership, Earth successfully withstood the first wave of the alien civilization’s assault. The three layers gradually restored order, and post-war reconstruction steadily progressed. Sigma rose to a new height of power, becoming a symbol in everyone’s hearts for the redefinition of “Earth.”
But then, while you were clearing old archives and residual data from the Zero Space, you discovered an encrypted record. The record revealed that long before Layer A began researching the Cube, Sigma had secretly leaked intelligence about the Cube’s emission of special electromagnetic waves to the alien civilization. He used this to fabricate the illusion that “Earth was about to start a Cube War,” drawing intense attention from the Interstellar Alliance.
In reality, Layer A had already blocked the electromagnetic wave leaks through shielding technology, but Sigma deliberately delayed updating the system, allowing the waves to escape freely. The alien civilization detected the signal and intervened in Earth’s affairs. Amid the chaos, Sigma gradually took control of the narrative and personally handed over the Cube in exchange for the alien civilization’s resource support, thereby becoming the new ruler of Earth.
He did not lie. He indeed saved Earth and brought about a brief peace.
But all of this was predicated on his calculated acceptance of Earth’s chaos, Layer A’s downfall, and the surrender of the Cube.
You stand before the ruins of the old council, looking toward the grand new seat of power in the distance, your heart heavy and conflicted. You supported this “hero” and witnessed him become the “ruler.”
Yet now, you are unsure—whether you have supported a new future or merely prolonged a greater lie.
[[The true face of Sigma]]You stand atop the crumbling ruins of the Layer A council, gazing up at the metallic spires of the new seat of power rising from the ground. The wind whistles through the shattered air corridors. At last, you realize that from the very beginning, you were nothing more than a carefully placed pawn in Sigma’s grand design.
Every battle fought side by side, every moment of trust and encouragement in times of crisis, every seemingly accidental guidance—all were part of Sigma’s setup to seize control of the entire situation. His obsession with the Cube, the “anger” toward the oppression of Layer B, even your initial “support” from Layer C—each was a perfectly played role.
Sigma never lied, but he never told the whole truth either. He used your movements between the layers to relay information, coordinate conflicts, and incite turmoil—all to manufacture a legitimate reason to overthrow Layer A. He used your trust to build a bridge leading straight to the pinnacle of power. And the Cube’s secret—that puzzle everyone believed was the key to salvation—was merely a bargaining chip in his dealings with the alien civilization.
“You’re a good person,” Sigma once smiled and said to you, “and I needed a good person to stand by my side.”
You lower your gaze to the encrypted record still clutched in your hand. You finally understand: you never changed the world. You merely became the cornerstone of a new one.
[[The Silent truth]]In the dim depths of Zero Space, you finally muster the courage to expose the true face of the hero Sigma and reveal the truth to everyone. But before you can speak, cold footsteps echo behind you.
Sigma slowly turns around, his gaze as cold and sharp as a blade. “Do you really think the truth matters? The game of power has never needed honesty.”
As his words fade, a sharp dagger slices through the air and pierces your chest in an instant. You collapse powerless, a final flash of shock and helplessness flickering in your eyes.
The truth remains forever silent in the shadows, and your voice is sealed away for all time.
BAD ENDINGAfter a fierce and covert power struggle, Sigma orchestrated a silent coup behind the scenes. Calmly, he approached you—his former comrade—from behind, and in a moment unseen by anyone, severed you in the shadows.
With the potential threat eliminated, Sigma smoothly seized leadership of the A Layer.
Now, the once-heroic Sigma has transformed into the new ruler, standing at the pinnacle of power, coldly watching the future of Earth’s three-layer structure. Every step he takes writes his own legend, while the you who was killed becomes a forgotten passerby, remembered by none.
[[puppet]]Sigma ultimately chose to hand over the Cube, accepting the terms set by the alien civilization. On the surface, Sigma became the ruler of Earth, holding the scepter and seated on the throne of the A Layer. But in reality, he had long since become a puppet emperor controlled by extraterrestrial forces.
The halo of power could not conceal the emptiness within; every one of his actions was monitored by the alien civilization, stripping him of autonomy. Earth’s future was quietly being rewritten by outside forces, and he was nothing more than a pawn in that cosmic game.
BAD ENDINGAs you passed through the high-temperature tunnels and stepped into Layer A, everything before you clashed sharply with the memory of that perfect “Utopia.”
The environment was still pristine, orderly, and spotless; the air fresh as an early spring morning, and the city floated amidst a web of blue-white light.
But the closer you approached, the more you felt a suffocating silence—
The people moving orderly along the streets walked in unison with vacant eyes, as if mechanically operated;
No one spoke, no one looked back, the city was eerily quiet like a hollow metal shell.
You ventured deeper into the city’s “low-function zone” and were shocked to find a group of thinly clothed people with hollow gazes.
They were maintaining energy hubs, cleaning sewage pipes, and sweeping ventilation shafts—tasks that should have been handled by automated systems, now replaced by human labor.
Approaching one worker, you froze—he was an old man you had seen before in Layer C.
“You… why are you here?”
The old man did not respond, mechanically repeating his task, with a branded mark on his forehead reading: “Adjuster.”
Someone whispered to you that these people were the “selected” elites from Layer C who entered Layer A—originally hoping to change their fate, but after being stripped of identity, will, and ability to express themselves, they were reprogrammed into the system and reduced to “managed labor.”
Inside Layer A, the society had quietly split into two worlds:
The upper echelon still sat high in the power center, controlling all resources;
While the “new residents” of the lower levels had long lost autonomy and were left only with toil.
You finally realized: this “Utopia” had long since spiraled out of control.
It was no longer the endpoint of an ideal society, but the highest form of oppression—a breeding ground of desire.
The true collapse had already begun—at the moment it became invisible on the surface of the Earth.
[[The Cube]]The 0-Space was deep and silent, as if time itself had been sealed away in this undisturbed dimension. You slowly pushed open the metallic-glimmering door, revealing before you a cube suspended in the void—the Rubik’s Cube, pure, perfect, yet utterly silent.
You approached, attempting every method to uncover its secrets. But the only response was a series of chaotic fragments and indecipherable structures. The Cube neither rejected you nor accepted you. It was like a mirror, reflecting only the seeker’s insignificance and confusion.
In the end, you realized:
The question was never whether the Cube could be solved,
But rather—why we are so obsessed with solving it.
[[The truth gradually surfaced.]] Earth's collapse was never the result of an alien conspiracy, but the consequence of a structural sickness from within. The mobility between layers grew increasingly restricted; the passage from C-layer to A-layer slowly sealed. Society became a machine freezing in place—its noisy surface masking sluggish decay and corruption underneath.
It was the B-layer that first sensed the crisis. They didn’t rise to "invade," but to survive—to shatter the chain that had long barred their path to destiny. They intended to use the existence of the Cube to shake A-layer’s authority, to release a signal powerful enough to fracture the established order.
And Sigma—the so-called "hero," cloaked in glory, hailed as a savior—he was neither a traitor nor a messiah. His role had always been that of the observer. He was commissioned by A-layer, and his sole duty from the beginning was to watch. To observe the Cube’s effects across layers, to report the resulting shifts so that those in power could decide the next course.
A hero does not intervene—he only watches.
And now, you finally understand: this civilization’s experiment was never truly about the Cube itself,
It was about whether we still remembered the connection we were meant to have with one another.
[[Suddenly, a shrill alarm sound rang out.]]Above the A-layer, the alarms began to sound—a long-forgotten signal that heralded all-out war. From the B-layer, the crowds surged like a swarm of ants between towers and light-bridges, clutching not just weapons, but fury born of soil and oppression. The once-imposing old order was being torn apart, piece by piece.
At that moment, a sealed message broke through the comms blackout—a grim update: negotiations between the C-layer and the alien civilization had failed. The opposing fleet had reversed course and was advancing toward Earth’s orbit. The next pulse-jump was projected to tear straight through A-layer’s defense grid.
It seemed like the end of everything.
But just then, Sigma appeared. He did not flee from the catastrophe poised to engulf every layer—he stepped onto the front lines.
“Earth is not dead yet,” he said, voice calm, yet carrying a power that no one dared question.
He offered no elaborate explanations, no defense against the accusations cast his way. He simply raised a weapon—one never before revealed to the public—as if it had always been waiting for this exact moment, as if fate itself had been holding its breath.
Some of the B-layer militants stopped in their tracks, turning toward the figure of this legendary “hero.” A-layer’s defense systems faltered, confused—but could not block his commands from reaching across the network.
Sigma wasn’t defending the old order. Nor was he blindly protecting Earth’s former glory. He set forth a new goal: for everyone, from every layer, to fight this war together—to give this planet, long corroded by its own hands, one final chance.
You stood beside him in silence. In that moment, even you couldn’t tell whether this was the beginning of redemption—or the doorway to an even deeper truth.
[[You stood at the edge of the ruins]]You stood at the edge of the ruins and called out to the B-layer commander preparing to launch the assault on A-layer.
You didn’t shout or rage—just spoke, calmly and clearly—and for a moment, the march of war paused.
“The question now isn’t hatred, or revenge,” you said, eyes fixed on the scarred, battle-worn soldiers before you.
“It’s whether we still have the strength to save a world on the brink of collapse.”
Above, the alien fleet loomed ever closer, their pulse energy rumbling like distant thunder, a forewarning of devastation.
Earth had no retreat left.
“Do we take one final stand—united—to resist the invaders?
Or do we hand over the cube, and gamble our future on a single compromise?”
Silence spread across the tiers of armored decks.
The weight of choice pressed down—not just between victory or defeat, but on whether Earth would still have a tomorrow.
[[Make a final stand and fight against the external invaders.]]
[[Hand over the cube.]]You joined forces with the rebels of Layer B, vowing to protect Earth from the incoming alien invasion. They gathered every ounce of strength and launched an unprecedented resistance, determined to defend their home to the very end.
But war is merciless. The alien civilization's technology far surpassed humanity’s—precise weapons shattered defenses, and every stronghold fell one by one. You, the investigator, failed to realize that the true threat wasn’t merely the invasion, but the secret hidden behind the cube.
As time passed, B Layer’s resistance gradually crumbled. In the end, Earth’s final defenses collapsed entirely. Civilization was reduced to ashes, a silent ruin drifting in the vastness of space.
Your efforts were in vain. In the depths of despair, you understood—Earth had missed its one and only chance at salvation. And the shadow of its destruction will forever hang among the stars.
BAD ENDINGYou chose to hand over the cube to the alien civilization, hoping to bring an end to the hopeless war. You acted in secret, but were quickly discovered by the authorities of Layer A. Driven by fear and the desire to maintain control, they refused to surrender the cube and deployed armed forces to stop you.
Conflict erupted once more. The people of Layer B, long past the point of restraint, allied with segments of Layers C and even the lower tiers of Layer A, launching a full-scale assault upward. In the chaos of their advance, the barriers separating the three layers were completely shattered. The structural balance of the "cocooned architecture" collapsed, and space itself began to fold inward—echoing with the fracture of an entire planet.
Everyone, regardless of rank or status, was forced to flee to the surface—Layer C. In that moment, there were no more social divisions, only survival.
And at the very center of the chaos—the cube slowly rose into the air before everyone’s eyes. It radiated a blinding light, then vanished without a trace.
The alien fleet halted instantly, ceasing all aggression. Soon after, a message arrived: the cube had reappeared on another planet. As part of the exchange, Earth’s civilization voluntarily signed an agreement, relinquishing its right to safeguard the cube.

The war came to an end, and Earth was granted a rare moment of peace. The rigid class divisions slowly began to dissolve, the environment gradually showed signs of renewal, and the scars of the past started to heal through unity and reconstruction. Though the road ahead remained filled with challenges, Earth was steadily moving toward a new hope—and a new future.
HAPPY ENDINGAs you pass through the scorching heat of the high-temperature conduit and step into Layer A, the scene before you is nothing like the perfect "utopia" you once remembered.
Everything still appears pristine—immaculate, orderly, and gleaming white. The air is as fresh as a spring morning, and the city itself hovers amidst a lattice of blue-white light.
But the closer you get, the more you feel an overwhelming sense of suffocating silence.
People move through the streets in perfect synchrony, their eyes vacant, their steps mechanical—like cogs in a machine.
No one speaks. No one turns around. The city is as quiet as a hollow metal shell.
You venture deeper into the “Low Function District” of the city and are startled to find groups of thinly dressed, vacant-eyed individuals.
They are maintaining energy cores, clearing waste pipelines, scrubbing ventilation shafts—tasks that should have long been automated, now reduced to manual labor.
You approach one of the workers and suddenly freeze—it’s an old man you once saw in Layer C.
“You... what are you doing here?”
He doesn’t respond. He just keeps repeating his actions mechanically, a branded mark seared into his forehead: “Adjuster.”
Someone nearby whispers that these people were once “elite” individuals from Layer C—handpicked to ascend to Layer A, hoping to change their fate.
But instead, their identities, wills, and voices were stripped away, and they were re-integrated into the system as “managed laborers.”
Within Layer A, an invisible divide has silently formed:
The upper echelon still resides in the power core, hoarding all resources.
But the “new residents” below have long lost their autonomy—reduced to nothing more than function.
You finally realize: this "utopia" has long since lost control.
It is no longer the final stop of a perfect society—it is the ultimate form of oppression, a cradle of unchecked desire.
And the true collapse had already begun, long before it was ever visible from the surface.
[[The other side of a hero]]You witnessed with your own eyes the collapse of Layer A—its cracks and distortions revealing that everything was far from what it seemed on the surface. Alarms blared in your heart, and your instincts screamed that Sigma was anything but simple.
Without hesitation, you broke away from his side and vanished into the chaotic shadows of Layer B. There, you joined the underground resistance, quickly becoming a vital source of intelligence in their eyes.
From the darkness, you searched for the truth, moving cautiously with each step, constantly evading your former companion—the one who seemed like a savior, yet sent a chill down your spine.
[[The truth gradually surfaced]]The truth gradually surfaced—the collapse of Earth did not stem from the direct invasion of an alien civilization, but from the deepening internal divide between social classes and the rigidification of the societal structure. Over time, the channels connecting Layers A, B, and C were progressively sealed, stifling mobility between the classes and bringing societal progress to a grinding halt.
The first to sense the danger were the residents of Layer B, caught in the cracks between the upper and lower tiers. Their growing dissatisfaction eventually ignited into widespread rebellion.
In an effort to preserve their power and dominance, the rulers of Layer A sought to regain control by leveraging the legendary “Cube,” said to possess boundless power. Unable to decipher its secrets themselves, the leaders of Layer A secretly entrusted the Cube to the leaders of Layer C, while deliberately leaking its whereabouts. This incited both conflict and foreign attention, turning Layer C into a zone of experimentation and strife. The involvement of the alien civilization thus became an external excuse and convenient cover for the class struggle.
As an investigator, you had long been entangled in this intricate web of power. Sigma’s mission extended far beyond crisis resolution; he was also tasked with covertly monitoring the Cube and reporting the shifts and sentiments of each layer back to Layer A’s leadership. The tangled interests and political maneuvering behind the truth proved to be far more complex and lethal than the apparent alien threat.
[[The rebel forces from Layer B]]The rebel forces from Layer B are closing in on the defenses of Layer A, and the outbreak of war is imminent. At this critical moment, news arrives—negotiations with the alien civilization in Layer C have completely collapsed. The hostile forces are preparing for a full-scale assault on Earth.
Caught between internal rebellion and external invasion, Earth faces an unprecedented crisis. With its fate hanging by a thread, everyone must now make a choice: unite to resist, or remain divided and await the inevitable fall into oblivion.
You begin to doubt Sigma’s motives and gradually lose your trust in him. Realizing that the true source of the crisis lies within the ruling class of Layer A, you decide to join forces with the rebels of Layer B. As war spreads and former allies become enemies, you take on the responsibility of uncovering the truth and reshaping the fate of Earth. The burden of change now rests on your shoulders.
[[protect their planet]]
[[overthrew the rule of the A-Layer]]The Earth's resistance forces united, vowing to protect their planet from the invasion of the alien civilization. They gathered every ounce of strength and launched an unprecedented defense, determined to defend their home to the death.
But war is cruel and unforgiving. The alien civilization's technology far surpassed humanity’s—its weapons precise and devastating, breaking through Earth's defenses step by step. The investigator never realized that the true crisis wasn’t the invasion itself, but the truth hidden behind the secrets of the Cube.
As time passed, Earth’s resistance gradually crumbled. In the end, its defenses fell completely, and human civilization was reduced to ashes—a silent ruin drifting through the cosmos.
BAD ENDINGThe rebels from the B-layer finally overthrew the rule of the A-layer, breaking the old class barriers. The once-oppressed B-layer took the place of the A-layer, becoming the new core stratum.
As power and resources were redistributed, the B-layer gradually transformed into a new A-layer, striving to rebuild Earth's future with new ideals and approaches. However, the shadow of history still lingered, refusing to fade.
After joining the emerging faction of the new A-layer, you gradually uncovered the root of Earth’s deeper crisis through the guidance of the Cube in Zero Space—the increasingly severe stratification had led to societal stagnation and a perpetual cycle of conflict.
Realizing that only by dismantling the rigid barriers between layers could this vicious cycle be broken, you decided to reveal the truth to the public and called for all layers to confront the problems together and negotiate solutions.
However, the former rebels from the B-layer, now the new ruling class, were unwilling to dismantle the status quo. Clinging to their newfound power and interests, they refused to overturn the system they had just seized.
Faced with this reality, you felt isolated and powerless. Though the new system you were working to build had taken shape, it remained riddled with contradictions and injustice.
[[retreat into obscurity]]In the end, you chose to retreat into obscurity, abandoning direct confrontation. You waited patiently for a future moment when humanity might reunite, hoping that when true change finally arrives, you could play a pivotal role in guiding Earth toward genuine harmony and coexistence.
