By six in the morning, Nyx no longer fit anywhere in the apartment except the middle of it.
Aiden stopped in the hallway and looked at the problem.
Nyx had folded himself across the kitchen threshold with the offended dignity of a creature inconvenienced by architecture. One wing lay half open over a chair that had survived the night only in theory. His tail reached the refrigerator.
Iris looked up from the table without surprise.
"He grew again."
"I noticed."
"That's not a cat anymore."
Nyx lifted his head from his forepaws.
"I was never a cat."
"You broke a chair before breakfast," Iris said. "That feels domestic in a very specific way."
Aiden stepped over the ruined chair leg on the floor and opened the refrigerator. Half the shelf space was already gone. Meat containers. Eggs. Two delivery boxes from last night. One sealed pack Iris had labeled for humans in black marker, because apparently that had become necessary.
Nyx watched the door open with total concentration.
"That one," he said.
"No."
"You opened it."
"That isn't consent."
Iris hid the start of a smile behind her cup.
Aiden pulled out one of the cheaper meat packs and set it on the counter.
Nyx stared at it.
Then at the better cut in Aiden's other hand.
"You insult me often for someone who sleeps inside my radius," he said.
"Eat the insult."
Iris set her cup down.
"Hana called at five thirty. She said if that thing gets any bigger before payroll stabilizes, she's adding him to the expense report under hostile logistics."
"Fair."
"She also said you were supposed to be at the office early."
"I know."
He had been awake before the call. The habit was becoming structural. Wake early. Check routes. Check messages. Check the door, the street, the angle of danger in ordinary things. Sleep had become something he entered carefully and left fast.
Outside the kitchen window, a delivery scooter cut through the wet morning. Somewhere downstairs a dog barked once, then again, then abruptly stopped. Aiden glanced toward the sound without meaning to.
Nyx noticed.
"You heard that yesterday too," he said.
"It heard you."
"No," Nyx said. "It heard you."
Aiden shut the refrigerator door a little harder than necessary.
He plated fruit for Iris because she would ignore breakfast if no one put it in front of her. He did it without comment. She noticed anyway.
"You should sleep tonight," she said.
"We have routes."
"That is not an answer either."
He looked at her. The blanket was gone now. Color had returned to her face over the last few days, but recovery still lived in the details. How carefully she stood. How often she hid a wince by changing the subject first. He noticed all of it. She noticed him noticing and disliked it on principle.
"I can work from the office today," she said. "If Hana keeps pretending I should rest quietly in a corner somewhere, I'm going to start sabotaging her filing order."
"She'd kill you."
"Then she'll have to do it alphabetically."
Nyx ate with the concentrated silence of a creature committing a moral act. Aiden packed his gear one-handed, checked the edge on his knife, and felt the morning settle into shape.
The shape felt wrong already.
Not danger. Not exactly.
Attention.
The ARES office occupied the second floor above a parts warehouse that smelled permanently of cardboard, oil, and rain. Their van was already open in the loading bay when Aiden arrived. Do-yun stood beside it in full gear, tightening the left strap on his shield harness. Min was sitting on a crate with coffee in one hand and a field med kit in the other, comparing the two with equal distrust.
Hana did not look up when Aiden entered.
"You are late by three minutes."
"Traffic."
"You live twelve minutes away."
"Exactly."
Joon was at the folding table with three printed route sheets, two tablets, and the expression of a man whose job description had become a practical joke.
"Good morning to you too," he said. "You look rested in the same way a knife looks rested."
Nyx ducked through the half-open door behind Aiden and immediately changed the room.
Not just because of the size.
Because everyone had to account for him now.
Min looked up first.
"Absolutely not," he said. "No. That's larger. You were smaller yesterday. I would testify under oath."
"You would do badly," Nyx said.
"He's right," Joon muttered. "That's not subtle anymore."
Hana finally looked up from the route sheets. Her gaze moved from Nyx's shoulders to the broken edge of one wing membrane where he had apparently clipped a doorframe somewhere on the way in.
"New rule," she said. "If he destroys rented property, it comes out of Aiden's share."
"Biased accounting," Min said.
"Accurate accounting."
She slid the route sheets across the table.
"We have four viable clears today. Two official. One private. One 'accidental release' that stopped being accidental the moment I saw who forwarded it."
Joon tapped the first sheet.
"Same observer receipt family as yesterday. Different desk. Cleaner paperwork."
The second.
"Same thing."
The third.
"Daesung subcontract through a broker who suddenly discovered we exist."
The fourth had no district stamp on it at all.
A maintenance corridor under the east flood channel. E-band on paper. Fast-turn contract. Decent money for the rank.
"Who sent that one?" Aiden asked.
Joon leaned back in his chair.
"That's the part I dislike. Nobody official. Routed through a materials handler I know by name but not by taste. He says another team withdrew after initial entry."
"Reason?"
"He wrote structural uncertainty, which is professional dialect for something made a man reconsider his confidence."
Hana capped her pen.
"We take two. Maybe three if the first one doesn't waste time. We need the money, the district wants a pattern, and if the market is going to study us, I prefer to decide what it sees."
Min raised his coffee.
"I support any plan based on money and spite."
"Naturally," Hana said.
Aiden looked at the sheets in silence.
Yesterday had made one thing clear. The pressure was no longer random enough to ignore. If they slowed down now, the district learned hesitation. If they rushed, the district learned hunger. Either way, someone kept notes.
He touched the flood-channel route.
"We do the official one first. Then this."
Joon looked at him.
"Because it pays better?"
"Because someone backed out."
Nyx jumped lightly onto the empty crate beside the table. The crate protested. He ignored it.
"At last," he said. "Work."
The first site sat under a municipal fitness center that should have smelled like chlorine and bad decisions. Instead it smelled of mold, old concrete, and the damp mineral breath of a dungeon that had settled into the lower service level three days ago and refused to become anyone's priority.
Association barriers cut the underground parking entrance into bright yellow lines. A junior evaluator stood under a portable lamp with a tablet in hand, trying to look professional in front of people he did not want to offend. He looked at ARES with the polite caution reserved for things discussed in rooms without becoming understood.
He looked at Nyx longer.
"Team count confirmed," he said. "Familiar entry approved under existing file."
"He's not paperwork," Min said on the way past.
The evaluator wisely pretended not to hear.
Inside, the dungeon had overwritten the service corridors with wet stone and narrow channels of black runoff. The air was colder than it should have been this close to the surface. Pipes crossed the ceiling in rusted bundles. A vibration moved through the floor every few seconds from the gym above, as if treadmills were running over a cave.
Do-yun took point at the first fork without needing to be told.
Min shifted left and back.
Aiden moved ahead of both by half a step.
Nyx vanished upward into the pipe-shadow.
That part of it had become routine too.
The first monsters came from the runoff channel.
Thin things. Pale-backed. Six legs working too fast for their size. They climbed out of the black water with the blind certainty of scavengers that had never met a consequence worth remembering.
The lead one rushed straight for Aiden.
Then stopped.
Not far.
Three meters, maybe less.
Its front claws scraped concrete. Its body went low. Not submission. Not intelligence. Just one broken instant of instinct colliding with something older than thought.
Then it screamed and lunged anyway.
Aiden was already inside the movement.
His knife went through the soft hinge below the jaw. He turned with it, let the body pass, and drove the second creature into the wall with his shoulder before it could reach Do-yun's blind side. Do-yun smashed the third flat against a pipe support. The fourth dropped from overhead and never landed. Nyx hit it in the throat mid-fall and carried it sideways hard enough to burst black blood across the wall.
Fast.
Clean.
Too clean to look normal from outside.
They kept moving.
The Core sat in a maintenance chamber where broken lockers had fused halfway into stone. Weak crystal clusters grew around it like frost around old damage. Two more scavengers died trying to hold the room. One died on Do-yun's shield edge. The other twisted for Min and lost its head on the way there.
Aiden destroyed the Core with one downward strike from the short blade he kept for crystal work.
The chamber shuddered once.
The black runoff retreated into cracks. The dungeon air changed by a degree, losing its pressure all at once.
"Seven minutes," Joon's voice said through the comm. "That is not helping my paperwork."
"Your paperwork is weak," Nyx said.
Min crouched by one of the bodies and looked toward Aiden.
"Tell me you saw that."
"Which part?" Aiden asked.
"The part where it forgot how attacking works for a second."
Do-yun wiped his shield and said nothing. His silence had weight when he used it. Aiden felt it, stored it, moved on.
"Wet footing," Aiden said.
Min looked unconvinced in a medically recreational way.
"Sure."
Outside, the junior evaluator recorded clear time with fingers that moved a little too quickly.
He did not ask questions.
That was worse.
By noon, the city had gone from damp to bright without committing to either. Their van was parked under the shadow of an overpass while Hana argued with a broker through one earpiece and rewrote half a supply order on her tablet at the same time.
Min had acquired lunch for everyone except Nyx, who had responded to that exclusion by stealing half of Aiden's chicken before the bag was fully open.
"He keeps doing crimes with eye contact," Min said.
"Then stop holding food like prey," Aiden said.
Nyx swallowed once and settled deeper across the bench seat, now far too large to pass for anything ordinary.
"Humans are slow with meals," he said.
"Humans cook meals," Iris said through the video call propped against the dashboard. "Try gratitude once. You might hate it."
Nyx considered the phone screen.
"No."
She smiled anyway.
She had spent the morning in the office with Hana and was now supposedly sorting invoice categories. Judging by the open spreadsheet behind her, she had also started a disagreement on purpose.
"How bad is it?" Aiden asked.
Iris angled the phone so he could see the table behind her. Equipment receipts. Utility bills. Medical follow-up. Fuel. Barrier fees. A highlighted line item labeled special feed requirement with Hana's note beneath it: this is the dragon.
"You're not poor," Iris said. "You're annoyingly close to stable, which is somehow worse because now Hana can explain exactly how stability dies."
From somewhere off-screen, Hana said, "Mostly through appetite."
Min leaned toward the call.
"Ask her if the dragon can be depreciated."
"I heard that," Hana said.
Aiden looked out through the windshield while they kept talking. A woman was walking a small white dog along the far side of the service road. The dog stopped, lifted its head, and stared straight at the van.
Then it tugged hard in the opposite direction.
The woman frowned, corrected once, then gave up and crossed the street instead.
Aiden said nothing.
Nyx, eyes half closed, said, "Again."
The second site lay under the east flood channel where the river split around a concrete control basin and forgot to become pretty again for several kilometers. Maintenance access ran through a fenced service yard full of rusted ladders, drainage pumps, and stacked pipe rings big enough to sleep in. No Association truck waited outside.
Only a broker's van.
One driver.
No logo.
Joon came in over comms before anyone asked.
"Materials handler confirmed withdrawal report. First team entered. Heard movement deeper in. Decided the money did not love them back."
Hana's voice followed immediately.
"This stays E-band unless reality argues hard. If reality argues hard, you leave. Min has authority."
"I know," Aiden said.
Min glanced at him.
"Good. Because I'd enjoy being obeyed for once."
The access stair dropped them into a concrete throat lined with old maintenance lamps. Water moved somewhere below the grates in slow black sheets. Every sound carried too far. Nyx went ahead this time, low and silent, his dark body almost disappearing between the support columns until only his eyes remained whenever he turned back.
At thirty meters in, he stopped.
Not because he had found the monsters.
Because he had found their direction.
Aiden felt it a second later.
Movement to the right.
Then above.
Then not moving at all.
He raised one hand. Do-yun locked his stance. Min stepped behind the column line.
The first creature dropped from the maintenance rail like a bundle of cable with teeth inside it.
Aiden cut through the fall and the body hit the walkway already opening. Not dead enough.
The second came from the drainage channel, broader than the first, all rope muscle and lamp-white skin. It hit Do-yun's shield hard enough to drive him half a step back. The impact rang through the tunnel. A third skittered along the wall to flank.
Nyx landed on it before it completed the turn.
For one instant the whole corridor became claws, wet concrete, and the black sweep of his wing catching emergency light. The tunnel felt too small for him.
Aiden saw the line of the fight before it finished forming.
Left support column.
Narrow rail.
Flood drop beyond.
He knew where the next body would fall before the creature moved.
He should have disliked how good that felt.
The broad one drove at Do-yun again.
Aiden moved past the shield edge, not toward the monster but toward where it would correct after missing him. It took the bait exactly once. Its jaws snapped shut on empty air. His knife opened the side of its throat. He turned with the recoil, stepped onto the rail, and kicked himself upward to catch the fourth creature as it launched from above.
His blade entered under the sternum and tore free hot.
The body fell into the black water below with a heavy sound and did not come back.
The last one should have charged Min.
It saw Aiden instead.
It slowed.
Actually slowed.
A visible failure in the shape of violence.
Its forelimbs trembled against the concrete. The mouth stayed open. Water dripped from its teeth. For a beat, maybe less, it looked less like a monster than an animal realizing the forest had just changed ownership.
Then Nyx tore out its neck from the side and the moment was gone.
Silence hit the corridor hard after that.
Only water.
Only breath.
Only the ticking hum of the lamps.
Min exhaled first.
"I am becoming extremely interested in all the things none of you tell me."
"Bad hobby," Nyx said.
The Core chamber sat deeper in, half submerged, with control gates frozen open in a crown of mineral growth. Blue-white crystal spread up the concrete walls in crooked veins. The Core hung above the waterline between two rusted beams, pulsing weakly through the dark.
No Boss. No hidden swarm. Just a dungeon that had scared one team and made room for another.
Aiden shattered the Core.
The crystals dulled immediately.
The pressure left the air.
And the hunger arrived so fast it almost felt like memory.
He looked down before anyone else could look at him.
One of the bodies had landed near the wall, half hidden by collapsed maintenance netting. Small enough to miss if you were tired. Fresh enough to matter.
Nyx was already there.
Of course he was.
He stood over the corpse with one forepaw on its shoulder and looked back once, not at Min or Do-yun, only at Aiden.
Move.
Min was checking Do-yun's arm where the shield impact had numbed it.
The comm line crackled with Joon asking for visual confirmation on crystal density.
Aiden crossed the chamber, crouched in shadow, and drove the knife in fast.
Heat.
Metal.
Salt.
Something deeper than taste, older than language, flooding upward through his teeth and throat and spine all at once.
The world sharpened by a thin, vicious degree.
Not stronger.
Clearer.
For the briefest instant, black lines slid across his vision.
HEART █████████ CONFIRMED
ASSI███TION STA███
Then they were gone.
Aiden wiped the blade once on the dead creature's hide and stood before the dizziness could become visible.
Nyx watched him for half a second too long.
"Better?" he asked.
"Quiet."
"That means yes."
When they came back up into daylight, the yard looked more inhabited than before.
Same broker van.
Same driver.
One additional car now parked beside the fence.
District plate.
A woman in a dark field jacket stood beside it with a tablet resting against one forearm. Not Lee Hae-jin this time. Older. Sharper. The kind of face that made clean questions sound expensive.
She looked first at the extraction case.
Then at Nyx.
Then at Aiden, as if that order mattered.
"That was fast," she said.
No greeting.
No introduction.
Hana's voice came through the comm a second before Aiden answered.
"If she doesn't give a department, she wants you to ask."
He didn't.
The woman's eyes narrowed by almost nothing.
"The withdrawal report may need revision," she said.
"Then revise it," Aiden replied.
Something like interest crossed her face and left again.
"We're trying to establish reliable expectations around your team."
Nyx stretched his wings once, forcing the broker's driver to take one involuntary step back.
"That seems difficult for you," he said.
The woman looked at him, then back at Aiden.
"Yes," she said. "It does."
Joon spoke into the comm, lower now.
"Aiden."
"What."
"New route just dropped into the queue. D-band review, twelve-hour response window, private side first and Association-certified second. No observer receipt. No district stamp."
Aiden looked at the woman beside the fence.
She gave nothing away.
"Who posted it?" he asked.
Joon was quiet for one beat.
"Daesung."
Across the yard, the woman finally smiled.
Not kindly.
Just like someone watching a line move from theory into design.
