The morning air of the East Union tasted like damp iron and stale soot, leaving a bitter, gritty residue on the tongue with every shallow breath.

Standing on the rusted, narrow balcony of our concrete housing block, the world looked entirely unrecognizable from the life that had existed just twelve months prior. It was 2027 now, and the old world—with all its trivial routines and easy comforts—had been completely erased.

In the far-off distance, cutting across the vast horizon, the sky bore the faint, bruised scars of the catastrophe. Here, thousands of miles away from the epicenter, the daily environment was spared from the worst of the devastation, but the atmospheric shifts were still undeniable. The sky was permanently stained a pale, unnatural violet. Massive, heavy purple clouds hovered above, refusing to drift naturally with the wind; instead, they gathered in slow, deliberate spirals, pulling continuously toward the southwest, charting a direct course toward the distant center of the Amazon forest where the massive purple stone had violently pierced the earth back in 2026.

When that colossal monolith first struck the heart of the jungle, the initial shockwave was only the beginning. The mysterious, volatile power radiating from the stone instantly began to warp reality, mutating the animals living within the forest into aggressive, unrecognizable horrors. But the disaster wasn't contained to a single continent. During the impact, the stone had fractured, sending a rain of very small pieces screaming through the atmosphere to fall in various places all across the globe.

It was a swift, brutal cosmic filter. People with fragile health died then and there, their bodies instantly collapsing under the sudden shock of the stone's energy. Yet, a rare few survived the exposure. Those adapted individuals emerged from the ash changed, awakening with terrifying, reality-bending powers—some possessed super strength or rapid healing, while others could actively manipulate fire, water, or air.

But I wasn't one of them. I hadn't received a gift or a curse. I was just a completely normal citizen, observing from the sidelines as humanity desperately tried to adapt to a living nightmare.

Down on the cracked asphalt streets below, the steady, rhythmic *thud-thud-thud* of heavy combat boots vibrated all the way up through the concrete foundation of my building. A long column of soldiers marched in perfect, grim unison, their grey uniforms covered in a fine layer of urban dust. Immediately following the impact last year, the surviving global governments had issued a frantic, universal alert. In a desperate bid to contain the spreading mutations, they had pooled every remaining resource to construct massive, monolithic walls completely surrounding the Amazon forest, turning the entire jungle into a sealed quarantine zone.

The scale of the crisis had utterly shattered the old geopolitical map. The world was no more a collection of small, independent countries. In the chaos, borders dissolved, and the globe reorganized into four massive, militarized main countries: North, South, West, and East. I lived here, deep within the territory of the East.

"Attention citizens," a harsh, metallic voice suddenly blared from a loudspeaker mounted atop a nearby steel watchtower. The sound scraped through the quiet morning, echoing sharply off the high-rise concrete walls. "The government is actively requesting normal citizens to join the borderline. High-tier hazard pay is officially active for all volunteers. Protect our borders. Ensure our stability."

The automated announcement repeated, its cold cadence droning over the heads of the civilians waiting down in the long, silent ration lines. This time, a few people actually stepped out of the crowd, walking toward the registration tents with hollow eyes and determined steps. The government was aggressively trying to tempt everyday people to volunteer for the walls, offering the highest pay left on the planet. For many, it wasn't a choice made out of bravery or fear; it was a cold calculation. With the food supply dwindling by the day, staying behind meant slowly dying of hunger in a gray room. Going to the borderline was dangerous, but at least it offered a different way out—a chance to fight for survival with a full stomach.

Instead of freedom, the world was now tightly led by powerful military leaders. A few surviving politicians had managed to secure seats as members of the global union, but their roles were no longer about policy or progress; their sole work now was to maintain baseline societal stability and manage the severe food crisis.

I pulled the collar of my worn jacket up against my chin, shivering slightly as an unnatural, heavy chill swept through the street. The air had become profoundly polluted since the stone arrived, thick with a heavy, pressurized quality that made the chest ache. In our sector, the massive indoor crop-domes still grew food, but the total amount was incredibly less than what the population required. Vegetables grew small, stringy, and tasted faintly of sulfur, and every meal was a strictly calculated variable in the equation of making it to tomorrow.

In the span of a single year, the entire human race had shifted completely from a life of comfort to absolute, unyielding survival mode. I watched the distant, swirling purple clouds gathering toward the center of the world for a few moments longer, tracking the slow rotation of the sky, before finally turning back toward the quiet interior of my room.

The flickering glow of the desk lamp buzzes softly in the corner of my room, casting long, erratic shadows across the cramped concrete walls. Stacked around me on the floor are yellowed, peeling volumes of ancient medicine—heavy textbooks preserved from an era when the world’s botany and anatomy followed predictable, earthly laws. At twenty years old, as a life science student navigating the fractured landscape of 2027, these books feel less like science and more like a collection of historical myths. The old rules of cellular biology simply don't apply anymore.

Not since the stone landed.

Out on the gritty streets of our sector, the citizens call it the **Devil Core**. To the high-ranking military officials of the union, it is a clinical hazard, a highly classified geographic anomaly to be contained behind concrete barriers. But to the researcher burning inside me, it is a beautiful, terrifying riddle that demands to be solved.

I am completely consumed by it.

I stay up for hours into the dead of night, tracing diagrams of old-world structures while my mind drifts to the phenomenon mutating our present. Why did the initial shockwave of purple radiation cause instantaneous cellular collapse in the fragile, killing them where they stood, while others adapted, absorbing the cosmic energy to manipulate the very elements of nature? How does a single celestial stone possess the blueprint to rewrite the DNA of an entire jungle?

It is a lethal curiosity. I know the core is an absolute death sentence, a volatile nightmare, but the desperate urge to analyze the catalyst of our broken world is completely drowning out the terror.

If I stay here in the quiet, monotonous sectors of the East Union, reading dead science and standing in ration lines, I will never get answers. The only path to the data, the only way to get anywhere near the epicenter, is the frontline.

I am not an Adapted. I don't possess elemental strength or rapid healing, and I am not a combat soldier trained to hold the line against mutated horrors. So, I chose the next best thing: the medical rescue teams.

The frontline medics.

Their jurisdiction requires them to venture into the high-risk blind spots just beyond the perimeter walls. They administer first aid to the bleeding infantry and hunt through the toxic, altered terrain to find lost soldiers separated from their units. It is a position that will place me directly in the wake of the contamination. It gets me close.

Breaking the news to my parents feels like a physical blow to the chest.

In our dim, cold kitchen, the air turns to absolute ice the moment the words leave my mouth. My mom instantly starts crying, shaking her head in a panic, staring at me as if I’ve just signed my own execution order. They argue fiercely, pointing out the window at the relative safety of our quiet sector, pleading with me to stay.

But I don't back down.

I drop to my knees right there on the cold floor. I beg them. I intentionally hide my burning, obsessive research drive behind a desperate, emotional plea for self-reliance.

"I need to be strong," I tell them, the lie tasting heavy and bitter on my tongue. "I can't just sit here in a room and watch the world fade away. I need to learn how to survive what is coming."

Slowly, worn down by the sheer persistence of my begging, their resistance crumbles into a hollow, defeated silence.

The next morning, the air at the Sector 4 registration point smells heavily of cheap disinfectant and the anxious sweat of dozens of citizens standing in line, all signing their lives over in exchange for the union's highest hazard pay.

When my turn comes, the processing officer stamps my paperwork without even looking up at my face. On the cold, flickering monitor, my identity locks into the military system in rigid, green text:

**ANYA. AGE: 20. EAST REGION RECRUIT.**

*Eastern Base Medical Rescue Division.* The countdown begins immediately. I have exactly two days before the transport airships arrive to ferry us to the primary military training camp.

Back home, the reality of the choice hangs over our household like a suffocating shroud of smoke. Mom has become a ghost. She moves through the concrete rooms in total silence, completely refusing to look at the tactical gear or the heavy canvas duffel bag sitting open on my bedroom floor.

My dad, however, tries to use patriotism to shield his breaking heart.

"Dying for our country... for the protection and preservation of the East Union... it is a respectful path," he says, his voice level, rigid, and forced into a disciplined frame as he stands over my things.

But I can see right through the soldier act.

Deep down, he is terrified. He isn't a military man; he is just a father who has forced himself to believe a grim, noble narrative so he doesn't collapse from the truth: his twenty-year-old daughter is walking directly into a war zone.

Now, the house is dead quiet except for the rustle of heavy fabric. Side by side, with heavy hearts and trembling hands, they help me fold my gear into the bag.

Preparing me for the horizon.

The morning of the third day arrives without a sunrise.

There is only a shift in the heavy fog—the pale, sickly purple light of 2027 bleeding through the concrete cracks of Sector 4.

The transport airship is already waiting at the mobilization gate.

An iron-gray beast, rusted at the seams and smelling of heavy aviation fuel. Its massive engines idle with a low, bone-deep rumble that vibrates through the soles of my boots and rattles the metal fencing nearby.

The goodbye is short. The military union doesn't allow lingering at the gates.

Mom grips the fabric of my tactical jacket until her knuckles turn stark white. Her lips tremble, tightly pressed together, refusing to speak a single word because she knows the moment she opens her mouth, her composure will completely fall apart.

Dad doesn't cry. He just stands rigid, placing a heavy, calloused hand on my shoulder, his posture forced into a strict, disciplined frame. He gives me one last, firm nod. The soldier act, played out until the very last second to mask the terror of a father losing his child to the unknown.

I pull away from their touch. I step into the dark, cold belly of the transport.

The heavy metal doors hiss shut with a pressurized seals, cutting off the sounds of the city outside. Through the small, scratched, reinforced window, I watch the silhouettes of my parents grow smaller and smaller until my entire childhood home shrinks into a speck of gray dust against the horizon.

There is no turning back now.

Hours bleed together as the transport cuts through the turbulent, choked sky.

We aren't flying straight to the Amazon—the Devil Core is thousands of miles away, locked across a vast ocean at the epicenter of the global disaster. Instead, we are heading deep inland, flying toward the heavily fortified heart of the East Union’s territory, where the primary military training camp is built to process new volunteers.

When the heavy landing ramp finally lowers, the world hits my senses like a physical blow.

The air here tastes entirely different from Sector 4.

It is thick, smelling heavily of diesel fumes, scorched metal, and the sharp, sour tang of mass anxiety radiating from hundreds of bodies. Giant concrete walls surround the entire perimeter of the base, stretching so high into the purple-hued sky that they loom over us like massive, unyielding tombstones.

"Move! Medical and Rescue volunteers, form up and line up by the steel barricades!"

The barked order belongs to a scarred squad leader standing on a raised platform. His uniform is pristine, bearing the silver, cold insignia of the Eastern Base Command.

He doesn't see us as people, or even as citizens. To him and the union, we are just a fresh shipment of raw parts being fed into the military machine.

They herd us like cattle into a cavernous, dimly lit briefing hall made of stark, cold concrete.

I look around at the rows of benches stretching across the room. The space is completely packed with hundreds of unfamiliar faces—a massive, desperate crowd gathered from every single corner of the East Union.

There are former medical students who left their half-empty universities, farmers from dying fields whose soil turned to ash, and ordinary citizens displaced from distant, bankrupt sectors.

To my left, a young guy from a coastal province stares blankly at his trembling hands, whispering a frantic, repetitive prayer under his breath. To my right, a girl from the northern border silently clutches a worn-out, scratched ration token, her eyes red and hollow.

I listen to the low, anxious whispers rippling through the benches. None of these people volunteered because of a "crazy curiosity" or a passion for science. They joined because their families were starving. They signed their lives away simply because the union promised hazard food rations to anyone who walked toward the perimeter.

I keep my mouth shut, guarding my secret in absolute silence.

In a room filled with hundreds of terrified, desperate souls, I am the only one who actually wants to be here.

The buzzing fluorescent lights in the hall suddenly kill, plunging us into total darkness.

A massive projector hums to life at the front of the stage, casting a stark, blinding beam of light across our pale, upturned faces. A high-ranking officer, his uniform adorned with medals, steps up to the steel podium, his shadow stretching across the wall behind him.

"Welcome to the frontline," his voice echoes heavily through the audio speakers, cold and unmoving. "You are the retrieval line. Your job is not to fight, but to go into the blind spots beyond the perimeter walls, locate the missing, and drag our soldiers back before the atmospheric contamination claims them. This is the reality of what you are up against."

The screen flashes, shifting to a new slide.

It is classified data—satellite feeds and ground-level recorded footage sent directly from the high-density containment zones surrounding the South American epicenter. A world completely rewritten by the Celest body.

The screen shows a forest, but the trees are deeply wrong. Their bark is as black as obsidian, twisting into unnatural, sharp angles, and pulsing with glowing, violet veins of liquid energy.

Then, a massive creature leaps directly into the camera's frame. It used to be a jaguar, but the cosmic radiation has completely fractured and rebuilt its biology. Its skull is split wide open, replaced by a jagged, crystalline horn protruding from its forehead, and its enlarged eyes burn with a volatile, unnatural purple fire.

The entire briefing hall goes dead silent. Someone in the front row gasps for air. The girl to my right instantly buries her face in her hands, her shoulders shaking violently as she weeps.

The terror in the room is heavy, thick, and suffocating.

But my heart isn't racing from fear.

I lean forward in my seat, my eyes wide, my pulse pounding hard against my ribs. The inner researcher inside me is screaming with absolute, unrestrained euphoria.

While everyone else looks away, I stare directly into the light of the projector. I trace the lines of the mutated muscle tissue on the screen, completely captivated and hypnotized by the terrifying blueprint of the stone.

It is beautiful. It is terrifying. It is the exact riddle I left my room to find.

The officer glares out at the crowd of horrified, pale faces, completely unaware that in the dead center of a room filled with broken people, a normal girl from Sector 4 is staring at the nightmare with a brilliant, dangerous smile.
