The dripping woke him before the pain did.
It landed near his ear in slow, heavy drops, too thick to be water. Each one struck the broken floor with a soft, wet tap that made the dark feel closer than it already was.
When Aiden opened his eyes, nothing changed.
Concrete hung inches above his face. Twisted steel pinned his left shoulder. Dust coated his tongue, his teeth, the back of his throat. Every breath scraped on the way in and burned on the way out.
He stayed still and counted to five.
Not because he was calm. Because panic wasted air.
His right hand moved first. Fingers. Wrist. Elbow. His left answered a moment later, and pain shot from his shoulder to the base of his neck so hard his vision flashed white behind the dark. His legs were worse. Buried under fractured concrete and something colder than stone, maybe rebar, maybe part of the floor above. He could not feel his right foot properly.
He breathed through his nose and immediately regretted it. Blood. Burnt insulation. Wet cement. Something sour and spoiled underneath all of it.
Dead things.
He shut his eyes again out of reflex, though it made no difference.
Iris.
The thought had been there since the building came down. Not loud. Not dramatic. Just fixed in place, harder than the slab across his legs. He had to get out. He had to find her. The rest could wait.
His throat felt flayed raw. When he swallowed, it scraped. He tried to remember the last clear thing he had seen before the street vanished under smoke and concrete.
A bus on its side.
People running in the wrong direction because there had been no right direction left.
The gate opening in the middle of the avenue like a black wound that had decided to stay open.
Iris on the phone, her voice thin with static.
Stay where you are.
I'm coming.
He had meant it when he said it. Then the city had stopped listening to human promises.
Something moved to his right.
Aiden went still.
It was not a person. He knew that before he had a reason to know it. The sound was wet, dragging, irregular. Not footsteps. Not breathing either, not anything built on lungs that worked the way human lungs were supposed to.
Another scrape followed. Closer this time.
His heart struck once against his ribs, hard enough to hurt. He turned his head as far as the concrete allowed and stared into the narrow space beside him.
At first he saw nothing. Then two pale shapes separated from the dark.
Eyes.
They were low to the ground and utterly still. Not glowing. Not dramatic. Just there, watching him with the patient focus of something that already knew he had nowhere to go.
Aiden did not move. Neither did the thing.
It was close enough now that he could hear fluid in its chest, a clogged, ragged sound that caught every few seconds. One leg dragged uselessly when it shifted. The smell coming off it was worse than the blood.
Rot. Infection. Monster.
The word arrived after the body had already understood the danger. He had seen emergency footage before, shaky phone videos and blurred broadcasts from districts that had been unlucky first. The real thing was smaller than he expected and much worse for it. A starving shape pressed together wrong. Too many joints in the front limbs. A back that bent where it should not. Skin stretched over a moving rib cage. A skull too long to be canine and too narrow to be anything human imagination would have made cleanly.
Its side was split open.
That was where the dripping came from.
The wound started below the throat and tore deep into the chest. It had been hurt badly, maybe by the collapse, maybe before that on the other side of the gate. Each time it dragged in a breath, something thick and dark shifted under the torn flesh.
It looked at him.
He looked back.
If it could still move properly, he was dead.
That at least was simple.
He checked his right hand again. Empty. His fingers searched the rubble in silence and found broken glass, powder, a loose bolt, then a strip of bent metal half-buried under the dust. It was not long and not sharp enough, but it had one broken edge.
Better than nothing.
He closed his hand around it.
The monster dragged itself forward a few centimeters. He heard the claws clicking now, one after another, uneven against the broken tile. One hind leg only twitched and scraped, useless as dead weight behind it. It was slow enough to be dying. Slow enough to still kill him if he made one mistake.
He wet his lips and felt the skin split again. No phone signal. No voices. No sirens anymore. Just the pressure over his chest, the iron taste in his mouth, and the thing in front of him deciding whether he was still worth the effort.
He tested the slab above him with his free arm.
Nothing.
He tried again and pain tore through his shoulder so violently he nearly dropped the metal strip. The monster twitched at the sound. Its head lifted, then lowered again, attentive now.
Think.
Not escape. Not yet.
First survive the next minute.
He adjusted his grip. The edge was jagged enough to cut if he drove it in hard. That assumed it came close enough. That assumed his arm held. That assumed he got one clean chance before it reached his throat.
Too many assumptions.
He hated gambling.
Then the creature dragged itself into a narrow line of gray light leaking through a crack overhead, and Aiden saw the wound properly.
Its chest had opened deeper than he thought. Beneath black blood and torn flesh, something dense moved inside it. Not lungs. Not exactly. Something lower, heavier, wet and dark red, contracting with a stubborn, ugly rhythm.
Pulsing.
The monster looked half-dead.
Half-dead was still more than enough.
Its gaze flicked from the metal in his hand to his face, then to the concrete trapping his legs. It understood weakness. Some part of him almost respected that. Even now, even bleeding out in the ruins of a human building, it still knew what mattered.
Good.
That made two of them.
How long had he been here? Time had stopped making sense sometime after the second night. Long enough for hunger to burn past emptiness and turn into something blunt and ugly. Long enough for the air to feel used up. Long enough for his body to start its cold arithmetic and decide which parts of him it could afford to lose first.
The monster moved again.
This time it tried to come fast.
Aiden struck before his thoughts could get in the way. The metal drove into the side of its face, too shallow and too high. The creature screamed, a rusted shriek that filled the pocket of concrete around them and shook dust loose from the slab overhead.
It lurched.
Most of the movement was collapse more than strength. Its weight crashed onto the debris over Aiden's legs instead of his throat. The impact jolted the entire gap. Claws snapped past his cheek and carved sparks from the wall, but without reach or force behind them. He smelled its blood now, hot beneath the rot, and jammed the strip of metal forward again, blind this time, pushing through a burst of pain so sharp his vision nearly vanished.
The jagged edge sank into the open wound.
The scream cut off.
The monster convulsed so violently its forelimb slammed across his trapped leg. Hot liquid spilled over his hand. Aiden kept driving the metal in, not because he was brave, not because he had a plan, but because stopping meant dying.
The thing thrashed once. Twice, weaker. Then it collapsed sideways against the concrete between them.
He waited.
Nothing.
Another second passed. Then the body twitched again, smaller this time, and the clogged sound in its chest turned wet and thin.
Not dead.
Close.
Aiden let his head fall back against the concrete. His whole body had started shaking now that the adrenaline was slipping out of him. Pain returned to every place it had been waiting.
He looked at the monster's chest.
At the torn opening.
At the thick red mass beating weakly inside.
He did not know why he kept staring until his stomach pulled tight hard enough to make him feel sick. The smell in the gap between them had changed. Beneath the rot and dust was something raw, hot, immediate. The creature opened one eye. Still alive. Barely.
The crack overhead shifted and let in one more blade of light.
It landed directly on the thing in its chest.
Wet. Red. Beating.
He could hear it now. Not loudly. But clearly.
Aiden stared at it, and his body answered before his mind could argue.
Hunger hit hard enough to wipe out the pain.
Not ordinary hunger. Not the hollow ache of missed meals or the dull weakness that came after long shifts. This was cleaner than that and far worse. It was a command. His mouth filled with saliva thick as blood. Every nerve in him turned toward the exposed organ like it was heat in winter, water in a desert, air at the bottom of the sea.
The monster's eye rolled toward him. Its chest rose once, fell, rose again. Slow. Weak. Waiting.
For a moment the entire world reduced to one thing.
The heart.
Still beating.
He had to get out.
He had to find Iris.
He knew that.
But in that crushed pocket of darkness, with the city silent above him and the blood smell filling his lungs, the beating thing inside the monster's chest felt more real than the street, the rubble, the promises, the world before the gate opened.
He reached for it.
