The stairs let him out into a corridor on the floor below, wider than the hall above and worse lit. He moved with the gun ready and the cut forearm held close, following the marker toward the center of the building.
His bandage had darkened through, though the cut underneath had stopped its worst bleeding. He flexed the hand every few steps to keep the grip honest.
Doors hung open along both walls, some torn off, the rooms behind them emptied of anything worth eating. The pack had swept this floor early on and moved along to better hunting.
That meant the survivors down here were the ones who had found somewhere worth hiding. He read the signs as he passed and kept his pace even. A floor this quiet still held whatever had made it go quiet.
The marker sat like a coal in the center of his vision, steady where the walls were not. Corridors that used to run straight now kinked and doubled, folded by whatever the Merge had stitched into the old floor plan.
Twice he passed classrooms where barricades had held and eyes tracked him through gaps in stacked chairs. Nobody inside called out to him, and the silence suited both parties fine. Locked doors were the one piece of advice the school had followed today.
A sound came from a side hall to his left, sharp and human, a voice working hard not to become a scream. He would have walked past it if the marker had not run the same way.
A voice was not his problem unless it stood between him and the commander. He turned the corner with the gun level and read the dead end in one look.
One of the grey things had backed a girl into the corner where the hall met a locked door. It kept its hunched back to him, too fixed on the cornered prey to have marked his steps.
The girl saw him over its shoulder, and he knew the face before the name arrived. Ava sat two rows ahead of him in the class he had walked out of that morning.
None of her usual ease had survived this far into the day. She had always been one of the bright ones near the front, close enough to see everything and far enough to pretend otherwise.
The creature stood square in the only way forward, which settled the question of whether it lived. He put a round through the back of its neck where the hide gathered, and it dropped without turning.
[ Enemy defeated. ]
[ EXP +20. (40 / 100 to Level 2.) ]
Four rounds left, and a body cooling across the doorway he still needed to pass. He stepped over it, reading the stretch of corridor beyond the locked door as he came.
Ava pushed off the wall and came after him, her voice climbing back toward something like control.
"Wait, you can't just leave me here, you have to get me out," she said, catching at his sleeve.
He stopped because the marker stopped, not because her hand on his sleeve meant anything.
"I don't have to do anything," he said, shaking the grip loose without turning all the way around.
She got a proper look at him then, and the recognition arrived in slow stages across her face.
"You sit at the back of my class," she said, the rest of it dying before she reached Mark's name.
"Say it," he said.
"I saw what he did to you, all of it, all year, and I never once said a word," she said, the confession coming out the way they always do when fear pries them loose.
She finished with an apology, quick and real enough as far as it went. It reached him years too late to be worth the breath it rode out on.
Sorry had always arrived after the fact, in his experience of the word. It came from people who regretted standing near the cost of what they had allowed.
"You're sorry because there's a monster in the hall, not because any of it was wrong," he said, and the two things were not the same to him.
He turned back toward the corridor and left her in the dead end with the cooling body. The marker still pulled, and her fear did not bend its direction by a single degree.
Guilt was cheap currency in a hallway full of teeth, whatever it had once bought in classrooms. He had stopped accepting payment in that currency a long time ago.
A second grey shape came around the far corner, drawn by their voices toward the same dead end. It read the two of them, dismissed the raised gun, then chose the girl with her back to the wall.
"Please," she said, the word cracking as the thing gathered itself to spring.
He did not stop walking, because he held four rounds and no reason to spend one on her. Whatever she lived through now, she would live through it the way he had learned everything, which was alone.
That morning he had asked a full room for help exactly once. The memory of the room's answer walked him straight past her plea without slowing.
For one step he weighed the round in the chamber against the cost of a scream at his back. He decided the scream was cheaper, and it was on his second step that the hall went bright.
Light changed all at once behind him, orange and sudden, throwing his shadow long down the corridor wall. He turned in time to see fire pour off Ava's open hands and wrap the creature from chest to jaw.
Heat reached him a full second after the light did, close and dry against the back of his neck. Whatever had been sleeping in Ava had woken with no screen to meter it and nothing to aim it but terror.
The Gobdog went down thrashing as the flame took it, hide splitting where the heat bit deepest. Ava stood over the wreck of it with her palms still burning, as startled as the thing she had killed.
She stared at her own hands as though they belonged to a stranger. The stranger had apparently been standing inside her the whole time, waiting for a bad enough morning.
He put Appraise on her before the flames had guttered out of her fingers. The result named something the entire day had failed to mention, and it stopped him where he stood.
[ Ava: Awakened. No Player interface. ]
The words hung plain over a girl who had made fire out of fear and nothing else. She carried no screen that he could find, only a power that had answered the moment her life came due.
The fire had taken something out of her to make its point. She had gone grey around the mouth, swaying, one knee close to folding before she caught the wall.
Until now he had used the skill on corpses and learned their prices. It read the living just as coldly, and what it said about them mattered considerably more.
He had assumed the System chose him and lit the whole world through the same window. That assumption died against the wall behind her, because her fire had never passed through anything he could see.
The Merge had dealt different keys to different people, and his key was only one of them. His interface was his alone, which made it an advantage and a blind spot in the same breath.
It also meant the building held more than prey and predators from here on. Some of the students he had written off this morning could bite back now.
A few of those might be worth having beside him, on terms he would set. The rest became one more variable to price before he turned his back on anyone.
Ava looked up from the smoking body toward him, wanting something that was no longer rescue. He left before she could shape it into words he would have to refuse.
A girl who could burn did not need carrying anywhere by anyone. That made her worth watching in the ledger where he kept people, instead of worth forgetting.
She would tell others what she had seen him do in this hallway. The telling would shape how the next survivors met him, and he counted that shaping a fair trade.
A reputation built on walking away was still a wall worth owning. It stood between him and everyone in this building who wanted something from him for free.
The corridor bent toward the center of the building, and the marker sharpened with every door he passed. Somewhere ahead of it waited the commander and the two hundred bodies it was worth.
He filed Ava under the things that had changed since morning and kept moving. The world would assume he knew its rules again, and next time he would know better than to agree with it.
