The floor shook again.
Jaehyuk hit the wall hard enough to taste iron.
"Up!" Mira barked.
He pushed himself off the stone as another blast rolled through the corridor. Dust rained from the ceiling. Hot dust. It scraped the back of his throat and made his eyes water.
Somin was kneeling three steps away, one hand pressed to a soldier's chest. The man's armor was split down the side. Blood soaked through his shirt in dark pulses.
"Hold still," she said. "If you keep moving, I can't close it."
"I'm not moving," the man said through clenched teeth. "I'm dying. Different thing."
"You're being dramatic."
"You're lying to me with a smile. Different thing too."
Jaehyuk looked past them.
The corridor was packed.
Not with enemies.
With people running.
Climbers. Porters. Healers. A child in a courier vest with a shard satchel hanging off one shoulder. Two Vanguard bruisers were hauling a third man by the armpits, his feet dragging uselessly over the floor and leaving a wet trail behind him.
Farther back, a gate sigil flickered red.
Then green.
Then red again.
The Tower alarm wailed overhead, a sound like metal being torn through wet cloth.
Mira cursed under her breath. "That gate was green ten seconds ago."
"It wasn't green," Jaehyuk said. "It was pretending."
She shot him a look. "That's not helpful."
"I'm aware."
Another impact.
The wall beside them cracked.
Not from a weapon.
From the Tower itself.
A seam ran through the stone like a lightning strike, then widened. Cold air spilled out. Not corridor air. Not dungeon air.
Something sterile.
Something wrong.
Somin's head snapped up. "Did you feel that?"
"Feel what?"
"The pressure. Like the floor breathed in."
Jaehyuk did feel it.
A pressure change. Tiny. Deep in the ears. The kind you got before a storm or before a sealed room opened underground.
He hated that he knew the difference.
"Keep healing," he said.
"I am healing."
"Then heal faster."
"You try it."
A shout came from the left.
"Ambush!"
Too late.
Three black shapes dropped from the ceiling grates into the corridor behind the evac line. Armor painted matte to swallow the torchlight. Tower-made masks. Vanguard.
One landed on the courier kid first.
The child screamed once.
Then the sound got cut off.
Mira moved before Jaehyuk did.
Steel flashed.
The first Vanguard soldier went down with Mira's blade through the gap under his ribs. She ripped it free and turned into the second one with no wasted motion at all. Her face was blank. Her eyes were not.
"Move!" she shouted. "Keep moving!"
The third soldier raised a hooked spear toward the courier kid's throat.
Jaehyuk crossed the space in one step.
Shadow Step.
The world narrowed. The wall behind the soldier snapped into place. The spear missed. Jaehyuk drove his elbow into the man's jaw, felt bone crack under the impact, and stole the weapon out of his hands.
The hook cut through the soldier's own neck when he stumbled back.
He dropped without a sound.
The courier kid was staring at him, trembling so hard the shard satchel rattled against their chest.
"Run," Jaehyuk said.
They did.
The corridor surged again.
From the front this time.
A second wave of climbers poured through a side passage, eyes wide, faces pale, some with blood on their sleeves, all of them talking at once.
"The east stair's collapsed!"
"No, it vanished!"
"There was a gate, I swear there was a gate!"
"The monsters spawned behind us!"
"Move!"
"Don't push!"
The smell hit next.
Burning resin. Blood. Sweat. The sour stink of fear in a crowded hall.
Jaehyuk could hear everything.
Boots on stone. Chainmail scraping. Someone vomiting behind a column. The wet hiss of Somin's healing light closing a wound. The tower alarm. Under it all, a low hum coming through the floorboards, like the whole structure had teeth and was grinding them together.
Mira shoved a panicked climber aside before they could trample the injured man Somin was treating.
"Watch it!"
"Sorry! Sorry, the gate's gone, I'm sorry!"
"Then stop apologizing and start breathing."
Jaehyuk almost laughed.
Almost.
Instead he grabbed the injured man by the back of the collar and dragged him into a narrower side hall.
"Here," he said.
Somin followed, knees nearly buckling under the effort of keeping pace. Her face had gone pale under the blood spatter on her cheek.
"I need thirty seconds," she said.
"You have ten."
"I hate you."
"Later."
She barked a laugh that ended as a cough.
The man on the floor was breathing in thin, shaking pulls. His chest wound had already gone half-purple from internal bleeding.
Somin pressed both hands over it and started the spell again. Light gathered between her palms.
Warm.
Steady.
Her breath hitched.
Jaehyuk saw the tremor in her fingers before she could hide it.
"Somin."
"I'm fine."
"You're shaking."
"I'm always shaking."
"That's not the same thing."
She swallowed.
Another alarm ripped through the floor. This one closer. Too close.
The side hall lights flickered.
Once.
Twice.
Then the far end of the corridor opened into a room Jaehyuk had not seen on any of his maps.
A blank chamber. Smooth walls. No torches. No windows.
A misaligned spawn point.
Not a new route.
A wrong route.
Mira saw it too. Her eyes narrowed. "That wasn't there."
"I know."
"How do you know?"
Jaehyuk didn't answer.
Because it felt intentional.
Because the Tower had done this before, only not on this scale.
Because the floor plan had moved when nobody was looking.
He stepped into the chamber first.
Cold hit him like a hand.
The room smelled of wet stone and copper.
At the center sat a circular sigil, still glowing from recent activation.
A reset node.
Somin stopped dead behind him. "Jaehyuk."
He stared at the symbol.
No.
Not just a reset node.
A forced respawn marker.
He'd seen one before.
On a floor that ended with bodies piled in a stairwell and a party leader smiling while he counted who could still move.
His jaw tightened.
"This wasn't here five minutes ago," Mira said.
"No," Jaehyuk said. "It wasn't."
The soldier on the floor groaned. Somin was still healing him, but now her light was thin, strained. Her breathing had gone ragged.
Jaehyuk checked the chamber ceiling.
Too smooth.
Too empty.
Then he noticed the floor markings.
Fresh scratches.
Recent boots.
The Tower had been moving people here.
Not randomly.
He felt his stomach go cold.
"Get them out," he said.
Mira blinked. "What?"
"Now."
"We just found shelter."
"No. We found a trap."
She looked at the sigil, then at him, then cursed.
"Somin, how long?"
"Twenty seconds," she said, teeth clenched. "Maybe less."
"Then you don't have twenty," Jaehyuk said.
The man on the floor grabbed his wrist with bloody fingers.
"Don't," he rasped. "Don't leave me."
Jaehyuk looked down at him.
The man's pupils were blown wide. Skin gray. He was close.
Too close.
"You'll die if she stops now," Jaehyuk said.
"I know."
"Then hold still."
The man laughed once. It sounded like choking.
"That what you tell your friends too?"
Mira swore. "This is not the time."
"It never is," Jaehyuk said.
The chamber floor shuddered.
Not from an explosion.
From below.
A second later, the sigil at the center flared blinding white.
Then the whole room rang like a struck bell.
Everyone doubled over.
It hit Jaehyuk in the teeth first. Then the ears. Then the bones.
A Tower reset.
Not a full one.
A partial one.
The lights above them blinked out.
Then came back on in a different arrangement.
Three people vanished from the chamber.
Not teleported.
Removed.
Their names flashed across the air for half a second in red text before the system swallowed them.
Jaehyuk's head snapped toward the doorway.
The corridor outside had shifted.
The evac route they'd come from was gone.
In its place was a dead end.
"No," Somin whispered.
Her voice shook. Not fear. Recognition.
"They're changing the floor," she said.
"Yes," Jaehyuk said.
"No, I mean... changing it on purpose."
The chamber door groaned.
Something struck it from the other side.
Once.
Twice.
Then the metal buckled inward.
Mira stepped in front of Somin without thinking.
Jaehyuk saw it and something in his chest tightened hard enough to hurt.
"Stay behind her," he said.
Mira gave him a flat look. "I'm not the healer."
"No," Jaehyuk said. "You're worse."
She almost smiled.
The door exploded inward.
A brute in Vanguard black came through first, shield raised, shoulders massive, face hidden behind a cracked mask.
Behind him, two more.
And behind them, a fourth figure.
Not Vanguard.
The grey coat was gone, but the same posture was there.
Same stillness.
Same finger tap against thumb.
Iteration 6.
They stood in the breach and looked past the bodies, past the blood, straight at Jaehyuk.
"You're too late," they said.
Jaehyuk's eyes narrowed.
"For what?"
Iteration 6's mouth twitched. Not quite a smile.
"For the next floor."
Mira lifted her sword. "You again."
Somin looked between them, breath coming fast. "Do you two know each other?"
Jaehyuk did not answer.
Iteration 6 tilted their head toward Somin, then back to him.
"It's already set," they said. "The Tower picked the marker."
"Marker for what?" Mira asked.
The brute charged.
Jaehyuk moved on instinct.
Shadow Step.
Steel screamed.
The first blow cracked against the wall where his head had been a blink before. Mira intercepted the second with a ringing clash that made everyone's teeth hurt. Somin dragged the wounded man by the shoulders toward the side passage, grunting with the effort.
"Do not let go!" she shouted at him.
The man grabbed her sleeve with both hands.
"I'm not," he gasped.
"You are if you pass out."
"Then don't let me."
"Rude."
Jaehyuk heard the humor in her voice and hated how badly he needed it.
The brute swung again.
Mira slipped under the shield and drove her blade into the man's thigh. He roared. Jaehyuk slammed the stolen spear butt-first into the back of his knee, and the giant crashed down hard enough to shake dust loose from the ceiling.
Iteration 6 didn't move.
They just watched.
"You planned this," Jaehyuk said.
"No," Iteration 6 said. "I warned you."
"About what?"
The chamber lights flickered.
The reset sigil on the floor blinked once, then turned blood red.
A system chime rang out over the alarms.
[NOTICE]
A name appeared in the air.
Not a death notice.
Not yet.
A floor mark.
Mira's head turned first.
Then Somin's.
Then Jaehyuk's.
The Tower had branded someone.
Marked for death on the next floor.
And the name was...
