Floor four was vast and dark and full of constructs.
Seven of them — larger than the floor three variant, the too-many-limbs replaced by a more consolidated form that was somehow more unsettling for its coherence. They occupied the chamber in loose positions that suggested territorial awareness, which meant intelligence, which meant they'd adapted since the floor three encounter.
The dungeon master was learning through its constructs.
Kael stood at the base of the descent and looked at seven constructs that wanted to eat everything he was, and thought about what Maren had said.
You are the source. The space between.
He activated Death Domain.
Not for harvesting — he'd never used it this way before, wasn't certain it was possible, was working from instinct and the deep certainty that the Class contained more than the System had formally described to him. He pushed the Domain outward and instead of opening it to receive death energy he turned it inside out — projecting outward, radiating, making himself the most obvious and overwhelming source of death energy in the chamber.
Come to me, the projection said without words. Come to the source.
All seven constructs turned toward him.
They came fast.
The first reached him in three seconds and hit the Death Domain's edge and — stopped. Not physically stopped. Stopped the way a fire stops at a firebreak — reaching, pressing, unable to cross the boundary between the Domain's interior and the source at its center.
It couldn't absorb the source. Like trying to drink the river by standing in it.
Kael raised his right hand.
[DEATH'S GRASP — RANK 2 — ACTIVE]
The grey extension of Death Touch shot outward at five meters range and hit the construct at its center of mass — and he felt what was there, felt the three centuries of absorbed energy compressed into a core the same way the Bone Colossus had a core, and he pulled.
The construct came apart.
Not dramatically — it deflated, the energy draining toward him through Death's Grasp the way water drains toward a hole, the mobile mass of it losing coherence and settling into a residue on the floor that the Death Domain absorbed automatically.
[CONSTRUCT — DEFEATED — ENERGY DRAINED]
[PRE-SYSTEM ENTITY — NON-STANDARD EXP CALCULATION]
[EXP GAINED: 87,000]
Eighty-seven thousand.
From one construct.
He didn't have time to process that number. Six constructs were still pressing against his Domain's edge, and the Domain's inside-out configuration was holding but it was costing him something — Spirit, he thought, draining at a rate that was manageable now but wouldn't be indefinitely.
He moved through them.
Not fast — deliberate, the way he'd walked into the wolf fight, letting them press against the Domain while he identified each one's center and reached with Death's Grasp and pulled. The second construct came apart like the first. The third was larger and pushed back against the drain and he had to hold the Grasp for four seconds longer, Spirit dropping faster.
[SPIRIT: 128 → 94]
The fourth construct did something he hadn't anticipated — it split, dividing its mass into two smaller forms that circled him in opposite directions, probing the Domain's edge for weak points.
Smart. Adapting in real time.
He split Death's Grasp the same way — projecting from both hands simultaneously, a technique the skill description hadn't mentioned but that the Class allowed because the Class had stopped being a set of described abilities somewhere around Level 15 and become something that responded to intention.
Both halves came apart simultaneously.
[EXP GAINED: 91,000]
[EXP GAINED: 91,000]
The fifth and sixth went the same way as the second and third — larger than the first, slower to drain, Spirit cost climbing.
[SPIRIT: 94 → 61]
The seventh construct did not come to him.
It stayed at the far side of the chamber and watched him dismantle its companions with the amber-lit attention of something that had been learning from everything it observed. It was the largest of the seven — nearly three meters of consolidated mass, the dark surface of it shifting slowly like deep water, and it radiated a cold that was distinct from the dungeon's ambient cold.
It felt, through Death Sense, like intelligence. Real intelligence. Not animal cunning, not dungeon instinct. Something that had been fed and fed and fed for three centuries and had grown beyond what the dungeon master had intended.
It spoke.
Not the way the bound dead had spoken — not language translated through bone. This was direct, pressing against Kael's mind with the blunt force of something that had never needed subtlety.
DEATH'S CHOSEN, it said.
"Yes," Kael said.
WE HAVE EATEN SEVENTEEN OF YOUR KIND.
"I know." He held the inside-out Domain steady. "I'm not here to be eaten."
EVERYTHING THAT COMES HERE IS EATEN. IT IS WHAT THIS PLACE IS.
"Then this place is about to change."
A pause. The construct's mass shifted — tightening, consolidating, preparing.
SHOW ME WHY, it said.
It moved.
It was faster than the others — not water-uphill wrong but genuinely fast, crossing half the chamber before Kael had finished processing that it had started moving, and when it hit the Death Domain's edge it didn't stop.
It pushed through.
Not all the way — the Domain held it at the boundary, but the boundary was bending inward, and Kael felt the Spirit cost spike to something alarming as he fought to maintain the configuration.
[SPIRIT: 61 → 38]
[WARNING: LOW SPIRIT — DOMAIN STABILITY COMPROMISED]
He didn't have time to drain it slowly. Didn't have the Spirit reserves for a four-second hold. He needed to end this in one motion or the Domain would collapse and the construct would reach him and the question of whether it could absorb the source would get answered in a way he strongly preferred to avoid.
He thought about Level 30. About the Undying Sovereign path. About his mother making tea in the records annex and Sera's three copies of the Veil research and Maren standing on the floor above holding a construct at bay with seventeen years of accumulated power.
He pulled every remaining Spirit reserve into Death's Grasp — all of it, the way you spend the last of your money when the alternative is worse than being broke — and pushed both hands forward and reached into the construct's mass and found the core.
It was enormous. Three centuries of absorbed death compressed into a knot of energy that pushed back against his Grasp with the force of something that had never been successfully challenged.
He pulled anyway.
It was not clean. The construct fought — pressed inward against the Domain, the boundary straining, something that felt like claws raking across the inside of his skull as the intelligence in the core resisted. His Spirit hit zero and the Domain collapsed and the construct's outer mass surged forward and he took the full weight of it across his chest and went backward three steps before the troll caught him.
His back hit the troll's chest and he stayed upright and kept the Grasp locked on the core and pulled with everything that had no System classification — pure will, the thing underneath Class and Level and multiplier, the thing the Ashrow had built in him before any of this existed.
The core cracked.
The construct came apart.
It didn't happen fast. It happened like the Bone Colossus had happened — slowly, the energy draining, the mass losing coherence, settling — but the intelligence in it didn't go quietly. It pressed against Kael's mind until the last moment, and in the last moment it said something that wasn't a threat.
FREE, it said, in a voice suddenly smaller than it had been.
FINALLY FREE.

Kael stood in the troll's shadow breathing carefully and let the level-up cascade settle through him — stats climbing, Death Affinity crossing two hundred, Intelligence approaching ninety, the Class deepening again with each threshold in the way he was beginning to recognize as its particular rhythm.
Maren appeared at the descent from floor three.
"I heard the Domain collapse," it said, scanning him quickly.
"Still standing."
"Barely." The ancient eyes moved to the residue on the floor — seven constructs reduced to nothing. "You drained them all."
"The last one pushed through the Domain."
"But you held the Grasp."
"Yes."
Maren was quiet for a moment. "The Death's Chosen in my records," it said carefully. "The ones who came before you. None of them got past floor three."
Kael looked at the descent to floor five.
[FLOOR 5 — DETECTED]
[DUNGEON MASTER — PRESENT]
[CLASSIFICATION: ANCIENT INTELLIGENCE — PRE-SYSTEM]
[LEVEL: UNREADABLE]
[NOTE: IT KNOWS YOU ARE COMING.]
[NOTE: IT HAS KNOWN SINCE YOU ENTERED FLOOR ONE.]
[NOTE: IT IS NOT AFRAID.]
[NOTE: IT SHOULD BE.]
He looked at the last line for a moment.
The System had never editorialized before.
He wasn't sure if that was reassuring or not.
"Spirit recovery time?" he asked Maren.
"At your current regeneration rate — forty minutes for full recovery."
"We have time." He sat down against the troll's leg, which accepted his weight with the solid indifference of something that had stopped caring about comfort three weeks ago. "Tell me about dungeon masters. Pre-System ones. Everything you know."
Maren sat across from him on the floor of the fourth chamber with the ease of something that had not sat on a floor in seventeen years and found it entirely acceptable and began to talk.
Sera appeared at the descent from floor three, notebook open, stylus moving before she'd finished descending.
"Start from the beginning," she said to Maren. "I want everything."
Above them, in floor three, the constructs they'd fought were gone.
Below them, in floor five, the dungeon master waited with three centuries of patience and seventeen Death's Chosen worth of confidence, in a chamber it had occupied since before the city above had existed.
Kael closed his eyes, leaned against the troll, and let his Spirit recover.
He had forty minutes.
He intended to use every one of them.
