The smell hit first.
Not blood.
Not rot.
Soap.
Cheap soap, damp cloth, and the stale sweetness of someone who had been locked in a room too long.
Jaehyuk stopped at the threshold of the neutral zone and narrowed his eyes.
"That's wrong," he said.
Mira glanced at him. "The smell?"
"Everything."
Somin shifted her healer's satchel higher on her shoulder. The leather creaked. Her hand was tight on the strap.
"You say that a lot lately," she said.
"Because it keeps being true."
The corridor ahead should've been calm.
Neutral zones were supposed to feel like a pause. A place where the Tower stopped pretending it was a slaughterhouse long enough for climbers to breathe, trade, patch wounds, and lie to each other about morale.
This one felt watched.
The air was too still.
Even the torches along the stone walls burned without flicker, as if the flame itself was scared of making noise.
A stale sweetness sat under the soap smell.
Old sweat.
Old fear.
Old people.
Jaehyuk's tongue pressed against his teeth.
They had just come up from Floor 56 after a four-hour push through a corridor maze that had shifted twice, one of the Tower's little jokes. Floor 57 had been a ruin with thin glass bridges over a dry cistern. Floor 58 had looked empty until the floor itself started cracking under their boots.
By the time they found this neutral pocket on 59, nobody wanted to talk.
That was probably why the Tower picked it.
Mira looked down the corridor again. "There are too many stalls."
There were.
Vendor tables lined both sides of the hall, but none of them had the usual noise. No bargaining. No shouting. No clatter of shard trays or hungry climbers arguing over potions.
Just rows of unopened crates.
Neatly stacked cloth. Bowls. Cups.
One stall had fresh fruit laid out in pyramids so perfect it looked fake.
Another had healing salves arranged by color.
All of it untouched.
All of it waiting.
Somin wrinkled her nose. "It smells like someone cleaned the place five minutes ago and then forgot to put people in it."
"No one forgot," Jaehyuk said.
Mira folded her arms. "Then what?"
He didn't answer right away.
Because he could hear it.
Not voices.
Breathing.
Very faint. Behind the walls. Or under the floor.
Something shallow and hesitant, like a person trying not to be noticed.
He took one step forward.
The board under his boot gave a soft, tired creak.
Somin jumped anyway.
"Don't do that," she muttered.
"Do what?"
"Look like you know what's about to happen and then don't tell us. It's rude."
"Noted."
Mira snorted once. It came out half humor, half nerves.
Jaehyuk walked past the first stall.
A brass sign hung above it.
FRESH SUPPLY EXCHANGE.
The letters were crisp. Newly painted. Too bright for this floor.
He ran a finger over the edge of the table.
Dust.
A lot of it.
But only under the table.
The surface itself had been wiped.
Recently.
Very recently.
"Someone's been here," Mira said.
"Yes," Jaehyuk said.
"No one's here now."
"Also yes."
Somin frowned. "That's not helping."
"Neither is the Tower."
She exhaled through her nose, then froze.
"Wait."
Jaehyuk looked at her.
She pointed.
At the far end of the neutral zone, near a vending alcove with its shutters pulled open, a woman sat on the floor with her back against the wall.
Her head was bowed.
Her hair hung in wet strands around her face.
A returnee.
At first glance, just another climber who'd made it out alive and used the neutral zone to collapse.
Then she lifted her head.
Mira's hand went to her sword.
Not because the woman looked dangerous.
Because she didn't.
Her eyes were open, but wrong somehow. Focused on nothing. The skin around them was bruised with exhaustion, and her lips kept moving in tiny silent motions, like she was trying to remember how talking worked.
Her badge was visible on her chest.
No guild mark.
Just a cleared-floor token.
Floor 54.
One of the missing parties from two days ago.
Somin took one involuntary step closer.
"Hey," she said softly. "Are you okay?"
The woman didn't answer.
She only stared.
Her fingers were curled around something in her lap.
A shard.
No, not a shard.
A key.
Tower-issued, the kind used for sealed storage rooms and administrative doors.
Jaehyuk's eyes narrowed.
That shouldn't have been in her hands.
The woman's gaze shifted to him.
Not through him.
To him.
A cold knot tightened under his ribs.
She knew him.
Or knew of him.
"What's your name?" Mira asked.
No response.
The woman's throat moved once.
Dry swallow.
Then she spoke.
Her voice was a rasp. A scrape across stone.
"Water."
Somin reacted instantly. She reached for her canteen, uncapped it, and crouched before the woman.
"Here. Slow. Don't choke."
The woman's hand twitched toward the canteen, then stopped halfway as if she'd forgotten how to finish the motion.
That was when Jaehyuk noticed the tremor.
Not in the hand.
In the wrist.
A tiny repeated jerk, like a puppet string pulled and released.
His stomach sank.
Mira saw it too.
"Don't drink yet," she said.
Somin blinked at her. "What?"
"I said don't drink yet."
"She asked for water."
"And I'm asking you to wait."
The woman's eyes moved from Somin to Mira.
Then to Jaehyuk.
Her lips parted.
A breath came out.
Wet. Shallow. Smelling faintly of metal and something medicinal.
Jaehyuk crouched, but not too close.
"Where were you found?" he asked.
The woman's pupils quivered.
"Door," she said.
"What door?"
Her mouth opened again, closed, opened.
"Down."
Mira's jaw tightened. "Down where?"
The woman's eyelids fluttered.
She looked exhausted in the most specific way Jaehyuk had ever seen. Not just tired. Used up. Like every instinct had been scraped from her and filed somewhere else.
That was worse than injury.
That was subtraction.
Somin set the canteen down slowly. "You came back from Floor 54?"
The woman nodded once.
Too slow.
Too careful.
Like she was copying a motion she'd seen somebody else do.
"What party were you with?" Somin asked.
No answer.
Jaehyuk watched her face.
Not the eyes.
The mouth.
The tiny pauses before each breath.
He knew that pattern.
He had seen it on people who came back after a rescue too late, after a stun field too long, after a poison mist that ate at the mind before it touched the lungs.
But this wasn't that.
This was clean.
Too clean.
He sniffed once.
The woman smelled like soap and old paper.
And underneath that, faintly, like rain on stone.
A Tower hallway.
Not a floor.
A hallway.
Mira stared at the key in her hand. "Where'd you get that?"
The woman looked down like she had only just noticed she was holding something.
Her fingers tightened around it.
Then relaxed.
"Found," she whispered.
Jaehyuk rose.
"No," he said.
Mira glanced at him. "What?"
"That key wasn't found. It was placed."
Somin's expression changed.
Not fear.
Recognition.
"Like the ledger," she said quietly.
He looked at her.
She nodded once. "The things that appear where they shouldn't. The Tower keeps doing that."
"It keeps doing a lot of things," Mira said. "I'd like one day where it does fewer."
The woman's head tilted.
Tiny movement.
A listening posture.
Not at them.
Past them.
Toward the corridor behind Jaehyuk.
His neck prickled.
He turned.
Nothing there.
Only the vendor stalls, the hanging lamps, the stale quiet.
Still.
No, not still.
Waiting.
He took one step back toward the woman.
"How many people came back with you?" he asked.
A long pause.
The woman blinked twice.
Then, very softly, she said, "Three."
Somin let out a breath. "Good. That means there are others alive."
Jaehyuk didn't move.
"Not alive," he said.
Mira looked at him. "What does that mean?"
"It means don't assume the Tower returned the same people it took."
The air changed.
A smell crept in from somewhere below the floorboards.
Wet stone.
Iron.
Then something sharp and thin, like ozone after lightning.
Somin's voice dropped. "You think she's a fake."
"I think she's a result."
"That's a disgusting sentence," Mira said.
"Agreed."
The woman's shoulders shivered.
She pressed both hands to her head.
Then she whispered, almost to herself, "No."
Somin stepped forward before anyone could stop her. "Hey. Hey, it's okay. You're safe now."
The woman laughed once.
A tiny cracked sound.
"Safe," she repeated.
That word came out wrong.
Not mocking.
Foreign.
Jaehyuk's eyes narrowed.
Mira's sword was halfway out of its sheath.
The woman looked up at Somin. There was a shine in her eyes now. Wet, but not from tears. From pressure. From something building behind them.
"I know you," the woman said.
Somin froze.
"You do?"
"Healer."
Her gaze moved to Jaehyuk.
"You too."
The sound of her voice changed on the last word. Softer. Almost human.
Jaehyuk felt a cold line run down his spine.
"What do you remember?" he asked.
The woman blinked.
Once.
Twice.
Then her mouth opened in a small, trembling shape.
"Not enough," she whispered.
Mira took another step. "What happened on Floor 54?"
The woman stared at her.
Then, as if the question had reached through a locked door in her skull, her face pinched in pain.
She folded forward, both hands clamping over her ears.
Somin moved to help. "Wait, don't—"
Too late.
The woman flinched hard enough to knock Somin's hand away.
Not with anger.
With terror.
The sound that came out of her next was barely a breath.
"No..."
Then she looked up at Jaehyuk again.
And smiled.
Not her smile.
A learned one.
A copy.
That was when Jaehyuk knew the Tower had put something inside her.
Not a monster.
Not a parasite.
A shape.
A returned body with an emptied room behind the eyes.
Mira whispered, "Jaehyuk..."
He didn't answer.
He was watching the woman's right hand.
The fingers had started tapping.
Index against thumb.
Once.
Twice.
His own habit.
His blood went cold.
Somin noticed the movement and went pale. "That's not possible."
"No," Jaehyuk said.
The woman's lips parted again.
This time the voice that came out was lower. Almost dry.
Measuring.
"Iteration..." she whispered.
Mira's sword came free with a metallic hiss.
The woman's eyes locked on Jaehyuk's face.
Her mouth moved one more time.
"Seven."
Then she leaned forward, close enough that Jaehyuk could smell the soap and the copper and the cold, dead air of a room that had never been meant to hold people.
And she whispered his iteration number.
