Out in the corridor, the dark lay unchallenged.

No emergency strips came up to tell the blind where to put their hands; she had torn those out when the building thought it could still choose.

The air was colder here. Pipes breathed faintly. Somewhere below, something heavy settled as heat bled and the building adjusted to being a tomb.

She started down the hall.

Her pace did not change.

There was no reason to hurry; nothing inside could escape.

She had made sure of that.

The stairwell door at the end hung crooked where a hinge bolt had given up. She touched it as she passed, her fingers leaving a new print over old scuffs.

The stairwell breathed a draft up the shaft, metallic and damp, a scent of rust that had not yet had time to form.

She took the stairs without counting.

Landings came and went like they were nothing more than a figment of her imagination.

On the second landing, a doctor lay with a pen still in his fingers as if the report mattered. On the third, a guard had crawled partway to a door and remembered too late that crawling implies a future.

Still, she did not slow.

At the corridor that fed the main building, she paused for the first time. Not because she doubted the way, but because the air there carried a faint otherness.

The smell of new gun oil, not the background stink of spent brass. A recent hand had handled a weapon for the sake of a chance to survive.

She listened to the quiet and heard no heartbeat close enough to be counted as other.

She moved on.

The body count thickened toward the lower floors where they had thought numbers could replace design.

She stepped through it, almost mindless in her quest for what was next.

Her hair dried in clots. Her skin cooled. The prints behind her stopped shining and settled into matte.

She kept moving forward, letting the creature inside of her guided her steps.

Her mind did not drift.

She did not think about the cabin. She did not think about the men. She did not think about the past.

The rage inside her sat low and hot and steady, like coals in a forge. It did not need words. It needed motion.

It needed work.

It needed blood.

But there was work ahead. One that would make her feel less detached.

Hopefully.

She crossed another hall.

A body slumped against a vending machine. She stepped around it.

A technician had curled under a desk and tried to make himself small. She reached under, pulled him out by the ankle, and broke his neck with one turn. The sound was quick. Clean. She moved on.

She cut through a lab.

Beakers lay smashed. A microscope had a handprint on it that was not hers. She found two researchers under a bench, pressed together, eyes wide in the dark.

One tried to speak. She tore both throats and wiped her hand on a white coat as she left.

The next door was stuck.

She drove her shoulder into it. The latch snapped. Inside, three soldiers had set up a machine gun on a tripod aimed at the hall. The belt hung loose; they were still feeding it. They looked up as she came through.

She took the loader first, breaking his fingers on the belt and then his jaw with the same motion.

The gunner tried to swing the barrel. She drove the muzzle into the floor and knee-struck his face. Bone broke under skin. He fell sideways.

The third man grabbed for a pistol. She tore the tripod free and smashed it down on his chest until ribs gave. The room went quiet.

She returned to the corridor.

At the far end, a steel shutter had half-closed.

A hand was crushed under the edge where someone tried to slide through.

She stepped on the fingers and the bones replied with a pop.

She pulled the person back by the wrist and broke the arm at the elbow. The scream was high and thin. She took the throat that made it. The scream ended. She pushed the body back under the shutter with her foot so the blood would not pool at her feet.

Another stairwell. Down two flights.

The smell of fuel. The generator room.

She had torn those lines already, but she checked.

A maintenance tech had bled out over the control box. She shoved him aside with her shin and ripped another plate free. Sparks snapped. The room stayed dark. Good.

Back into the spine of the building. Left, then right. Her pace never changed. The rage never rose or fell. It sat there and did its job.

She found a group of four moving together with flashlights.

Their lights cut thin cones through dust. They whispered. They tried to watch every angle.

One saw her shadow and fired. The muzzle flash blinded his friends. She was already among them.

She took the wrist with the light and twisted until it snapped. The beam rolled on the floor. She kicked it into another’s face. Plastic broke teeth.

She swept low, cut a hamstring, stepped over the fall, and hit the last in the throat with the edge of her hand. He dropped to his knees, choking. She let him crawl two feet and then broke his neck.

Silence again.

She paused, listening.

Air moved under a door on the right. She shoved it open. A small office. File cabinets. Two more doctors hiding behind them.

She flipped the cabinet with one hand. It crashed down on them. One still moved under it, gasping. She put her weight on the metal until the sound stopped.

Back into the hall.

She followed the path the creature had chosen.

The control room was done. The labs were done. The barracks were done. There were still rooms that smelled like fear. She went to those.

On the next level, she reached a long corridor with twin doors at the very end. Thick.

There were new scratches around the latch. Fresh prints on the push bar. Something alive waited there. Not her problem yet. She turned the other way and cleared six more rooms. When those rooms were done, she turned back.

She did not hurry.

Everything alive in this place would meet her before dying. The order did not matter.

She reached the twin doors and placed her hand on one panel.

Cold metal kissed her palm. She pushed. Hinges groaned. Bolts popped.

The panel shifted and opened a hand’s width. Air moved across her face, cold and clean compared to the halls behind her.

She walked toward it, knowing that what she was looking for was not in this building.

------

Down below, Zubair had torn his cell open and left the others to break theirs. He followed the smell of her and the silence she left. He reached the last door in the main corridor and shoved it wide.

Noah stood there with a gun pointed at his head.

Noah smiled.

The hammer clicked back.
