Darkness here didn’t fall—it oozed. It seeped from the damp walls, dripped from the ceiling with the smell of lime and ancient, stagnant salt. It was a physical weight, pressing against the eyes, trying to shove them back into the skull.

  ?I came to from the rhythmic thudding of my own heels against stone.

  ?Drag. Scrape. Pause. Drag.

  ?My head felt like a bell that had been struck with a sledgehammer and then left to vibrate. The hum wasn't just in my ears; it was inside the gray matter, drilling new pathways between neurons.

  ?— ...crude work. Inefficient, — the voice inside my skull was dry, like rustling parchment. It wasn’t an auditory hallucination. It was a thought that wasn’t mine. — You didn’t just break the circuit, Iron. You collapsed the local reality matrix. If I hadn’t cushioned the recoil, your brain would have boiled out through your ears.

  ?"Shut up," I tried to say, but only a wet wheeze escaped my throat.

  ?The movement stopped. The hand gripping my collar released me, and I slumped onto the cold, slimy stone. It felt like heaven. Cold stone meant stability. Cold stone meant heat transfer—I could cool the fever raging in my chest.

  ?"Alive," Efrem spat somewhere above me. He sounded like a bellows with a hole in the leather—wheezing, strained. "I was betting against it. Thought I was dragging a corpse just to feed it to the tunnel."

  ?I forced my eyes open.

  ?We were in a collector. A massive, cylindrical gut of the earth, lined with stone blocks so old they had fused into a monolith. There was no light, save for the faint, sickly luminescence coming from... me.

  ?I looked down at my chest. Through the soaked, mud-caked fabric of my jacket, the green light pulsed. Not a steady glow, but a jagged, nervous rhythm. It looked less like a lantern and more like an open radiation wound.

  ?— Efrem... — I pushed myself up on one elbow. The world spun. My center of gravity felt wrong, shifted. — The Obelisk...

  ?— Gone, — the old man cut in. He was sitting a few paces away, leaning heavily against the wall. In the dim green light, he looked like a gargoyle carved from swamp clay. His left sleeve was torn off, revealing a makeshift bandage soaked black. — Vaporized. You didn't just blow it up, boy. You... erased it. One second it was there, screaming to the high heavens, and the next—a vacuum. Air rushed in to fill the void so hard it knocked trees down for a hundred paces.

  ?He fumbled in his belt, produced a flint, and struck a spark. A small, sputtering torch flared up, casting long, dancing shadows.

  ?— But that’s the good news, — Efrem said, staring at the flame. — The bad news is that you screamed.

  ?— Screamed?

  ?— Magically. That blast was a howl heard by every sensitive in the Sector. You declared your position to the entire Order. We aren’t hiding anymore, Iron. We are running. And we are losing ground.

  ?I tried to sit up fully. My right hand—the one fused with the crystal's influence—felt strange. Heavy. I looked at it.

  ?The skin wasn't just pale; it was translucent. Underneath, where veins should have been blue, a network of emerald capillaries throbbed. They didn't follow human anatomy. They formed sharp angles, geometric loops. The "wiring" was rewriting my biology.

  ?— Don't be afraid of the upgrade, — Zeno’s voice whispered, smooth and arrogant. — Flesh is weak. Flesh burns, freezes, rots. The lattice is eternal. I’m giving you a structural reinforcement. Accept it.

  ?"Get out of my head," I snarled aloud.

  ?Efrem looked at me sharply.

  ?— He’s talking to you?

  ?— Zeno. He says... he says he reinforced me.

  ?The old man’s face twisted in a grimace of disgust. He spat a glob of bloody phlegm onto the floor.

  ?— He didn't reinforce you. He’s putting down roots. That crystal isn't a tool, Iron. It’s a lifeboat. Zeno knew he was doomed in the Citadel. He copied his mind—or the worst parts of it—into the lattice. Now he needs a carrier. A body with enough capacity to hold him.

  ?— He lies, — Zeno retorted instantly. — The old rat is afraid. He knows that with my knowledge, you don’t need him. Ask him about the tattoo on his forearm. Ask him why he knows the layout of the Dead Loop.

  ?I looked at Efrem. The torchlight flickered over his arms. They were covered in grime and old scars, but under the soot on his left forearm, I saw lines. Faint, white lines where ink had been burned out with acid or fire.

  ?A crossed-out circle. The mark of a broken oath.

  ?— You were one of them, — I said. It wasn’t a question. It was a statement of fact. My engineer’s mind slotted the data point into place. His knowledge of the Order’s protocols. His ability to build mana-dampening traps. His survival skills.

  ?Efrem didn’t flinch. He looked tired, infinitely old.

  ?— I was an Overseer. Third Circle. Logistics and Disposal. I’m the one who threw the bodies of "defects" like you into the lime pits when the experiments failed.

  ?The confession hung in the damp air like toxic gas.

  ?— Kill him, — Zeno suggested casually. — He’s a butcher. He will sell you out at the first opportunity to buy his pardon.

  ?— Why did you save me? — I asked, my hand instinctively moving to the knife at my belt. My fingers were numb, alien.

  ?— Because I got tired of the smell, — Efrem said simply. — And because everyone deserves a chance to ruin the Order’s day. Now get up. We have to reach the Junction before he does.

  ?— He? — I frowned. — You mean the squads?

  ?— No. Squads are slow. Squads need orders, maps, logistics. I mean the thing they sent into the tunnel after us.

  ?Efrem stood, wincing as he put weight on his bad leg. He pointed the torch into the darkness of the tunnel behind us.

  You might be reading a pirated copy. Look for the official release to support the author.

  ?— Listen.

  ?I held my breath. [The Will to Live] stopped broadcasting damage reports and focused on auditory sensors.

  ?At first, there was only the dripping of water. Plip. Plip.

  ?Then I heard it.

  ?Scrape.

  ?It was the sound of metal dragging over stone. Heavy, lazy, rhythmic.

  ?Scrape... Thud.

  ?A step. A heavy, uneven step, as if one leg was heavier than the other.

  ?— What is that? — I whispered.

  ?— A Hound, — Efrem replied, his voice devoid of emotion. — Not the machines. A person. Or what’s left of one. When a guard fails the Order... spectacularly... they don't execute him. They remake him. They fuse armor to his skin. They pump him full of alchemical rage and bind his soul to the mana signature of the one who escaped.

  ?My stomach turned over.

  ?— Kyle?

  ?Efrem looked at me.

  ?— If that was his name... then yes. It’s Kyle. He can’t stop, Iron. He doesn’t need food, he doesn’t need sleep. He feels only one thing—the itch of your magical trace. And the only way to scratch it is to rip your heart out.

  ?Scrape.

  ?The sound was louder. Closer.

  ?— Move, — I said, forcing my body to obey. — Where does this tunnel go?

  ?— The Dead Loop was a drainage system for the Old Capital. It goes under the swamps, under the mountains. It has outlets... if you know where to look.

  ?We began to move. I didn't walk; I shuffled, leaning on the damp wall. Every step sent a jolt of pain through my ribs, but the fear of that metallic scraping was a better motivator than any painkiller.

  ?We walked for what felt like hours. The tunnel twisted like a dying snake. Sometimes we waded waist-deep in vile, oily water. Sometimes we crawled over collapses where the ceiling had given way centuries ago.

  ?And all the while, the argument raged in my head.

  ?— Go left, — Zeno whispered as we approached a fork. — The airflow is fresher there. The right path reeks of methane and stagnation.

  ?— We go right, — Efrem said aloud, not stopping.

  ?— Why? — I stopped, wavering. — Left feels... right.

  ?— Because "Left" leads to the ventilation shafts under the Citadel, — Efrem grabbed my arm and yanked me toward the right, into the gloom. — Your "friend" wants to go home. He wants access to the Central Node. He’s trying to drive you back into the lion’s mouth because that’s where he can access the network.

  ?— He lies! — Zeno’s voice spiked with anger. — The right tunnel is unstable! Look at the stress fractures in the archway! It will collapse on us!

  ?I looked up. My engineer’s vision, sharpened by the crystal, saw the stress lines in the stone. Zeno was right. The ceiling here was critical. One vibration could bring it down.

  ?But Efrem was already limping into the darkness.

  ?— Efrem, the roof! — I hissed. — It’s unstable!

  ?— Exactly, — the old man cast a grim look over his shoulder. — That’s the point.

  ?And then I understood.

  ?Scrape.

  ?The sound was close. Maybe two hundred meters behind us. The echoes magnified it, turning it into the breathing of a giant beast.

  ?Efrem wasn't leading us to safety. He was leading us to a weapon.

  ?— You want to bury him, — I realized.

  ?— I want to survive, — Efrem corrected. — And for that, we need to bring the mountain down. Keep walking. Step softly. Don't touch the walls.

  ?We moved deeper into the "Right" tunnel. The air here was thick, heavy with dust. The floor was dry—ominously dry. Above us, tons of rock hung in a delicate, deadly balance.

  ?— Suicide, — Zeno commented, his tone shifting from angry to clinically detached. — The probability of us surviving the collapse is less than 14%.

  ?— Better than 0% if Kyle catches us, — I muttered.

  ?We reached a section where the tunnel widened into a small chamber. Wooden support beams, black with rot, held up the fractured ceiling. They looked like the ribs of a skeleton that had given up hope.

  ?Efrem stopped. He turned to face the darkness we had just come from.

  ?— This is it. Pass me the crystal.

  ?I recoiled, clutching my chest.

  ?— No.

  ?— Don't be an idiot, Iron! — Efrem snapped. — I need to overload the supports. A directed mana pulse. I don't have the juice. You do. Give it to me, or we both die here!

  ?— He will steal it, — Zeno whispered. — He will take the power and leave you to the Hound. Do not give him the source.

  ?I looked at Efrem’s outstretched hand. I looked at his eyes—cloudy, desperate, hard.

  ?Then I looked at the supports.

  ?Physics. It was just physics. I didn't need to give him the crystal to break a rotten beam. I just needed leverage. Or resonance.

  ?— I won’t give you the crystal, — I said, stepping back. — But I will bring the roof down.

  ?— You? — Efrem stared at me. — You can barely stand!

  ?— I don't need muscles. I need sound.

  ?Scrape.

  ?From the darkness, a figure emerged.

  ?It was a nightmare of steel and meat. Kyle had grown... larger. His armor had been hammered directly into his body—bolts pierced his shoulders, holding the pauldrons in place. His face was a ruin: the nose I had broken was gone, replaced by a flat iron grate. One eye was human, wide and bloodshot with madness. The other was a red alchemical lens screwed into the socket.

  ?He dragged a greatsword that looked like a sharpened slab of a tombstone.

  ?"Foouuund yooouuu..." the voice was wet, bubbling. It wasn't speech; it was the sound of lungs filled with blood trying to form words.

  ?Efrem raised his staff, a futile gesture against such a tank.

  ?— Run, Iron! — he yelled, charging forward. Not to fight—to distract.

  ?But I didn't run.

  ?I closed my eyes. I reached into the crystal—not to surrender to Zeno, but to grab the raw energy he was hoarding.

  ?— What are you doing? — the voice in my head sounded alarmed.

  ?— Resonance, — I thought. — Every material has a natural frequency. Stone. Wood. Bone.

  ?I focused on the rotting wooden beams holding up the millions of tons of rock above Kyle’s head. I didn't blast them with fire. I didn't hit them with force.

  ?I started to hum.

  ?A low, guttural sound, amplified by the crystal.

  ?Vmmmmmmm.

  ?The crystal in my chest vibrated. The green veins on my hand flared blindingly bright.

  ?The wooden beams groaned. They didn't burn—they started to shake. The vibration matched their internal structure, amplifying the stress.

  ?Kyle swung his sword, swatting Efrem aside like a rag doll. The old man hit the wall with a sickening crunch. The monster turned his red lens toward me. He took a step.

  ?Thud.

  ?The floor shook.

  ?— Amplitude reached, — Zeno whispered, sounding almost impressed. — Structural failure imminent.

  ?I opened my eyes and pushed the vibration from my chest, through my hand, into the air.

  ?— Drop, — I commanded.

  ?The main support beam didn't snap. It exploded into dust.

  ?For a split second, there was silence. Kyle looked up, his human eye widening in sudden clarity.

  ?Then the world ended.

  ?The ceiling came down. A landslide of rock and earth crashed onto the armored figure. There was no scream, just the terrible sound of metal being crushed like tin foil and stone grinding against stone.

  ?The shockwave threw me backward. Dust filled my throat, blinding me, choking me. I crawled, blindly, scrambling away from the expanding cloud of debris.

  ?When the rumbling finally stopped, there was only silence.

  ?The tunnel behind me was gone. Sealed by a wall of fallen rock.

  ?— Efrem! — I coughed, the dust tasting of copper.

  ?Silence.

  ?I activated [The Will to Live], forcing my eyes to see through the dust.

  ?A hand stuck out from under a pile of rubble near the wall. Not Kyle’s armored gauntlet. A human hand, clutching a broken staff.

  ?I scrambled over the rocks, digging with my bleeding fingers. I pulled stones away, ignoring the pain in my own fused hand.

  ?I dragged him out. Efrem was limp. His chest wasn't moving.

  ?— No, no, no... — I pressed my ear to his chest.

  ?Nothing.

  ?— He’s dead, — Zeno stated. — Tactical sacrifice. Acceptable losses. We are alive. Move on.

  ?I sat back on my heels, staring at the old man’s gray face. The only person who had helped me without asking for my soul first.

  ?And then, faintly, I heard it. A hitch. A rattle.

  ?A breath.

  ?He was alive. Barely. Crushed, broken, but alive.

  ?I looked at the wall of rock blocking the path back. Kyle was buried. But was he dead? Creatures like that... they don't die easily.

  ?I looked at Efrem. I couldn't carry him. Not far. And we were kilometers underground.

  ?— Leave him, — Zeno urged. — He is dead weight. He slows us down. Take his supplies and go.

  ?I looked at my glowing green hand. I felt the cold logic of the crystal trying to rewrite my morality.

  ?"I am an engineer," I whispered to the dark. "I fix things. I don't discard them."

  ?I grabbed Efrem by his collar and began to drag.

  ?Step. Drag. Wheeze.

  ?We were going deeper into the Dead Loop. Toward the unknown. With a monster buried behind us and a ghost trying to eat my mind from the inside.

  ?I wasn't a hero. I was just a stubborn defect who refused to be part of the equation.

  ?"Hold on, old man," I rasped. "We're not done yet."
