"Say it again."
Mira's blade was at the entity's throat.
Not a throat, really. More like a seam where the floor's flesh had folded into a shape that could talk.
It smelled like wet stone and hot metal.
It trembled under the edge of her sword.
"I said," the thing rasped, "the Tower is keeping something above."
Somin swallowed.
The sound was loud in the chamber.
Too loud.
Jaehyuk didn't move. His eyes stayed on the thing's mouth, on the way its teeth clicked like broken porcelain.
"Above where?" he asked.
The thing laughed.
A dry, scraping sound.
"Above the floors you've been told to care about. Above one hundred. Above one fifty. You think the Tower ends at two hundred because that's the number they gave you."
"Who told you that?" Mira said.
The thing twitched against her blade.
The smell got worse.
Like pennies in rainwater.
"The ones who go missing," it said. "The ones who don't come back. The ones who climb too far and learn the shape of the ceiling."
Somin's face tightened. "That's not an answer."
"It's the only one you get for free."
Jaehyuk crouched.
He was close enough to hear the thing breathing through its cracked lips.
It sounded wet.
Stuck.
Painful.
"What are you?" he asked.
The thing's eyes shifted to him.
Not to Mira.
Not to Somin.
To him.
Recognition flickered there.
That made his skin prickle.
"You know what I am," it said.
Jaehyuk didn't answer.
He did know.
Not the exact type. Not the category. But he knew the feeling of a floor that had been split open and left to crawl.
Something made by the Tower.
Something that had learned how to suffer.
Somin stepped forward until she was shoulder to shoulder with him.
Her voice was careful.
"You said people disappear because of what's above. How?"
The thing smiled.
Its lips split at one corner.
Blood welled there.
"Selection," it said.
Mira's sword hand tightened.
"Say more."
"No." It hissed. "Make me."
Jaehyuk stood.
"You don't want that."
"I don't want anything."
"Liar," Mira said.
The thing's eyes slid to her. It stared at the line of blood dried on her wrist.
"You're one of the strong ones," it murmured. "The Tower likes the strong ones until it doesn't."
Mira didn't blink.
"Try me."
Jaehyuk raised a hand.
Not to stop her.
To think.
The chamber around them hummed. The old archive shelves behind them rattled faintly, as if the floor itself had started to breathe.
He could smell dust in the air.
Old paper.
Somin's healing light carried a faint scent of copper and mint when she got nervous. It was there now.
Sharp.
He knew because she'd burned through her mana on the last fight, and the Tower had given them this room after.
Given.
That word again.
Nothing in the Tower was given.
It was paid for.
Or taken.
"Seven regressors," Jaehyuk said.
The thing froze.
Mira looked at him.
Somin frowned. "What?"
"The archive," Jaehyuk said. "The count. One through seven. Iteration 4 dead. Iteration 6 integrated. Iteration 7 pending."
The thing's smile thinned.
"So the room worked," it said.
Jaehyuk's stomach went cold.
"You knew this was here."
"I knew it would be found. Eventually."
"By who?"
"By the one who keeps asking the wrong question."
Mira's blade pressed harder.
A thin line of dark fluid welled at the thing's neck seam.
It didn't seem to care.
"Wrong question?" Jaehyuk said.
"You keep asking why you were chosen," it said. "You should be asking what you were chosen for."
Somin went still.
The air felt tighter.
The kind of quiet that makes your ears ring.
"Chosens are still chosen," Mira said.
The thing gave a little shrug.
The motion made something inside its shoulder crack.
"No. Sometimes they're made. Sometimes they're found. Sometimes they're pulled from one place and put in another."
Jaehyuk watched its face.
It wasn't lying.
Or it was lying in a way that didn't matter.
He knew that feeling too.
"Above Floor 150," he said. "What's there?"
The thing breathed out through its nose.
Steam curled in the cold room.
"You ever wonder why nobody comes back clean after the deep floors?"
Somin swallowed again.
"Answer the question."
"I am."
Mira glanced at Jaehyuk.
He gave a small nod.
Let it talk.
The thing's eyes had gone distant, like it was listening to something under the floor.
Or above it.
"The Tower doesn't just test climbers," it said. "It watches for type. It watches for pressure. It watches for the ones who bend but don't break. The ones who can keep memory when the world tries to peel it off."
Jaehyuk's jaw tightened.
Somin looked at him.
Not with fear.
With the dawning shape of a bad thought.
"You're saying regressors aren't accidents," she said.
The thing smiled at her like she'd finally asked something interesting.
"No. I'm saying accidents are how you explain things you don't understand yet."
"Then explain it," Mira said.
The thing laughed again.
It tasted like rust in the air.
"Seven showed up in the count because seven was the first shape that mattered. Before that, the Tower tried other ways. Some died. Some broke. Some survived wrong. The Tower kept the useful parts. That's what selection is. Not mercy. Not destiny. Utility."
Jaehyuk felt his thumb tap against his index finger.
Once.
Twice.
He stopped himself.
"Useful for what?"
The thing looked at him for a long moment.
Its skin had a grain to it, like stone trying to pass for flesh.
"For the thing above," it said.
Silence.
Mira's sword didn't lower.
Somin's breathing turned shallow.
Jaehyuk felt the words land in his ribs.
The thing above.
Not a boss.
Not a gate.
Not a floor.
Something with a position.
A relationship.
Like the Tower was built under it.
"Above what," Jaehyuk said.
The thing's gaze went to the ceiling.
A long time passed.
Then it said, very softly, "Everything."
The word crawled across Jaehyuk's skin.
He tasted dust.
Dry as paper.
Mira didn't lower her weapon, but her eyes changed.
Not fear.
Calculation.
She was the kind of person who could hear a cliff crack and start measuring the fall.
"What's it got to do with the disappearances?" she asked.
The thing's grin widened.
Too wide.
"You noticed," it said. "Good. The missing ones aren't dead. Not always. Some are taken up. Some are pulled out of the count. Some are kept where you can't see them."
Somin's voice came out thin. "Taken up where?"
The thing looked almost pleased.
Like it had waited for this exact fear.
"Above."
Jaehyuk stared at it.
"You said that already."
"Because you still don't like the answer."
He didn't.
Not at all.
His mouth had gone dry.
He could feel the air against his tongue. Stale. Old.
The chamber seemed smaller than before.
The shelves behind him crowded in.
Paper smelled different when it was old enough. This room smelled like that. Like hidden things. Like records that had been left shut too long.
"Why tell us?" Somin asked.
The thing's eyes flicked to her.
Then to Jaehyuk.
"Because you've already been told by everyone else in pieces. Because pieces make you easier to manage. Because the Tower loves a climber who thinks he understands the wall he's climbing."
"And you don't?" Mira said.
"I know the wall is alive."
That landed hard.
Somin made a sound in the back of her throat.
Jaehyuk thought of the archive.
The reports.
The charts.
The word integrated.
The way the Tower had said welcome back.
Not like a machine.
Like a person.
A very old, very patient person.
"Who are you really?" Jaehyuk asked.
The thing laughed.
"A bad piece of evidence."
Not an answer.
But maybe the only honest one it had.
Jaehyuk held its stare.
"What did the seven regressors have to do with selection?"
This time, the thing didn't answer right away.
Its tongue touched the split in its lip.
There was blood there.
The metallic smell thickened.
"Seven was the number that kept surviving long enough to matter," it said. "Seven was the number that learned the Tower's habits without losing the shape of the self. Seven was the number that could be compared."
"Compared to what?" Somin asked.
The thing's eyes narrowed.
"To each other."
Mira went still.
Jaehyuk didn't.
He felt the floor under him seem colder.
Seven regressors.
Not just seven tries.
Not just seven failures.
Seven things the Tower could measure against one another.
A selection process.
A set of trials within the trial.
"You're saying we're not the first," Jaehyuk said.
The thing's face shifted.
Something like pity, maybe. Or contempt.
"You're the first one asking it out loud."
A pulse ran through the chamber.
Low.
Deep.
Not sound.
Pressure.
The shelves rattled again.
Dust fell from the ceiling in a fine grey rain.
Somin looked up.
"Do you feel that?"
Jaehyuk did.
A strange vibration in his teeth.
Like distant machinery starting up.
Mira felt it too. Her gaze snapped to the doorway.
The corridor beyond had gone dark.
Not dim.
Dark.
Dead black at the edges, as if the light had been swallowed.
Then the Tower notification appeared.
Not in his status window.
In the air.
Huge.
White letters.
[NOTICE: MIDNIGHT RESET PREPARATION]
Somin's face drained of color.
"No," she said.
Mira cursed under her breath.
The thing on the floor laughed once.
A sharp bark.
"There," it said. "You hear it now."
The chamber lights flickered.
Once.
Twice.
The archive shelves shook hard enough that a binder fell and struck the floor with a slap.
Then another notification appeared.
[LIVE FLOOR STATUS: ACTIVE CONFLICT DETECTED]
Jaehyuk's eyes widened.
A live floor.
Not a sealed chamber. Not a boss room.
A live floor still full of climbers.
Still moving.
Still fighting.
The Tower was preparing a reset inside it.
"That's not possible," Somin whispered.
Mira's voice turned razor flat. "It is if the Tower doesn't care who dies in the room."
The thing's smile came back.
Nasty now.
Hungry.
"You wanted the truth," it said. "The Tower is done waiting."
The floor lurched.
Not metaphorically.
Actually.
Jaehyuk stumbled and caught the edge of the desk.
His palm slapped wood.
Hard.
The impact sent pain up his arm.
The sound of distant screaming rolled through the corridor outside.
Then another.
Closer.
Metal rang.
Someone shouted.
Mira moved first.
"Out," she snapped.
Somin grabbed Jaehyuk's sleeve. Her fingers were cold and slick with sweat.
"What does it mean, reset?" she said.
He already knew.
He hated that he knew.
His voice came out low.
"It means run."
The thing on the floor started laughing again.
Then it began to convulse.
Its back arched.
Its mouth opened too wide.
And from somewhere above the chamber, from somewhere no one could see, a low bell sounded once.
Not a warning.
A count.
The Tower was beginning to reset.
Inside the live floor.
And the first wall in the corridor cracked open with a sound like midnight breaking its teeth.
