They hit the first designated floor at the ten-hour mark.
Floor 273, by Vasik's notation, a number Kiran recognized from the descent three weeks ago because Floor 273 had a characteristic his pulse-rhythm integration remembered: the ambient mana signature carried a frequency he associated with old grief, the kind that had settled into the architecture over years rather than being actively generated. Not an entity floor. A floor where what had happened to the people who'd passed through it had left residue.
The seam network's main corridor ran through Floor 273's boundary layer without entering the floor. They didn't enter. But Kiran felt the floor's content through the construct eye's degraded thermal and through his integration: twelve heat signatures, stationary, positioned throughout the floor interior at irregular intervals.
Bodies.
Not recent. The thermal signatures were barely warmer than the floor's ambient temperature. Cold bodies, days-old, positioned in the patterns of people who hadn't expected to stop where they stopped. Not arranged. Fallen.
Daveth, from the rear, said: "What's on the floor?"
"Divers," Kiran said. "Dead."
A pause. "Ours?"
"Can't tell at this resolution. The signatures are too cold."
Sato kept moving. The amber light moved with her and they kept to the seam. Not stopping for dead divers in an inaccessible floor was a rule Kiran had learned before Floor 50 — one of the rules that the surface dive briefings included with the same flat affect as equipment checks. If you can't reach them and can't help them, mark the location and continue. There were people paid to note casualties and people paid to dive, and the two categories had learned not to confuse themselves.
He marked the floor in his memory and kept climbing.
---
They reached a wider section of seam at Floor 271 and Daveth came up beside him.
This happened rarely enough that Kiran noted it: Daveth at his left, keeping pace, the silence of a person who was working up to something rather than not saying anything. He'd been doing it for an hour. The particular silence.
Kiran waited.
"The twelve signatures," Daveth said.
"Yes."
"I know who they are."
He looked at Daveth. The amber light from Sato's position three meters ahead showed the soldier's face in profile, the high forehead, the jaw that habitually held tension even at rest. "How?"
"The positions. The distribution. The way they fell." He paused. "It's a pattern I know. Six in forward positions, two on each flank, four in rear cover. It's how Vorn's tactical units descend when they're moving through a floor they expect to be hostile." He paused again. "It's how my old unit descended."
"Your old unit," Kiran said.
"Not *my* unit. The unit structure I came out of. The 34th Deep Response. Vorn rebuilt it after the first Emergence. Used it for controlled descents." Daveth's voice was even. "They sent units to control the upper floors. Forty divers each time. Six separate attempts in the last two years."
"None of them made it past Floor 200."
"None of them made it past Floor 200," Daveth confirmed. "The 34th was the fourth unit. They reached Floor 273. That was the deepest any of Vorn's tactical units got." He looked at the floor boundary, the invisible wall between the seam and the floor where twelve dead people lay in a pattern he recognized. "Lieutenant Commander Asha Bergren. She led that unit."
The name was careful in his mouth. The particular care of someone saying a name they'd been carrying for a long time.
"She was your squad leader," Kiran said.
"She was." Daveth watched the floor boundary go by as they passed it. Then the next section of seam opened and Floor 273 was behind them. "I signed on for this run to find her body. That was the original reason."
Kiran was quiet.
"I know what the Abyss does to bodies," Daveth said. "I'm not expecting to find her intact. I was expecting to find something — her unit, the position they were in when they stopped, what hit them. The 34th was the first unit that tried to map the upper floors systematically rather than just descend. They had protocols. They had information that never made it back." He paused. "There's data up there in a hundred dead data recorders that Vorn would very much like to have."
"And you'd very much like to give it to him?"
"I'd very much like to know what happened to them." His voice flat. Not hiding anything, the flatness of someone who had processed this and arrived at a position that required no performance. "Vorn thinks she failed. Failed to reach Floor 200, failed to collect the floor data, failed to come back. He's already replaced the 34th with the 38th." He paused. "She didn't fail. They got to 273. That's further than anyone Vorn sent. The data recorders on twelve dead bodies are better data than anything the 38th will collect if it's currently in the upper floors."
Something in that sentence.
"If?" Kiran said.
Daveth looked at him. A pause that was a different kind of silence than the one before, the silence of deciding whether to share information that had context. "I got a transmission before the seam entrance. Garbled, partial. The seam network kills comms at depth. But the header was from a surface relay." He paused. "The 38th dropped in at Floor 265 two weeks ago. Full tactical unit. Forty-four divers. Their stated mission, in the header, was 'recovery of strategic assets.'"
"Which assets?"
"The header didn't say." Daveth's expression. "But the 38th is equipped for combat, not recovery. The distinction matters."
"The 38th is currently in the upper floors," Kiran said.
"Was, two weeks ago. They were at 265 then. In the time we've been in the seam network, they could have moved in either direction."
Kiran thought about this. A forty-four-person military unit, equipped for combat, in the upper floors of the Abyss. Two weeks ago at Floor 265. Their surface route was through Floor 265 and the primary seam corridor.
"Did your transmission identify a contact?" he asked.
"Yes," Daveth said. "The officer in command."
"Who?"
A pause. "General Aldric Vorn."
Kiran stopped walking.
Sato, three meters ahead, stopped without turning around. She'd been listening.
Vorn in the Abyss. Not directing an operation from the surface — descending himself. The man who had spent the last decade trying to seal the Abyss from the outside was inside it, at Floor 265, with forty-four combat-equipped soldiers.
"When did you know this?" Kiran asked.
"Two weeks ago." Daveth's voice even. "Before the wound. Before the organ system. I knew before I told you."
"Why now?"
"Because we're going to Floor 265 and you should know what's there." He paused. "And because we're past the point where holding it would serve any tactical purpose."
Kiran looked at him. Daveth looked back, the flat assessment of a person who had decided to be accountable for the decision he'd made. Not defensive. Accountable.
"Copy," Kiran said.
He started walking.

Floor 272 had entities.
Not the pilotfish escort of the lower floors — these were different. Denser. Faster. The entities of the upper deep, the floors below the sanity line that Kiran had navigated on his way down, were built from the Abyss's more active conceptual layers. These weren't curiosity-shaped things drawn by a novel frequency. They were hunters, or something adjacent to hunters, the deep ecology's predator-shaped organisms that had evolved to take the Abyss's resources by force rather than by proximity.
Three of them in the main floor corridor. Visible from the seam boundary, the construct eye's thermal imaging catching their heat signatures: mobile, high-metabolic, triangulated around a resource node in the floor's center.
The seam ran through the floor boundary layer but the main arterial seam above this floor required passing through it. The floor entry was unavoidable.
Kiran stood at the boundary and assessed.
The caretaker code's effect on these entities would be different from its effect on the lower floors' biology. These weren't wound-derived creatures. They were Abyss-native, built from the System's designation protocols rather than the underlying body's biology. The code didn't have a programmed response in the entities' architecture. What it had was residue, the marker of a frequency associated with the Abyss's own deep processes, old enough to be read as potentially significant rather than foreign.
It might slow them. It might not.
"Floor entry," Sato said.
"Yes."
"Entities?"
"Three. High-metabolic. Mobile."
"Engaged with the resource node."
"For now." He looked at Markos on his shoulders. His right arm pressed the meaning-reader's weight against him. His left hand was free for the blade. He did the inventory: one blade, depleted memory archive, one memory activation remaining before the archive hit the threshold where he couldn't be sure what would be consumed. "I need both hands free to move through the floor fast."
Sato understood the implication. "Daveth."
Daveth stepped up. "I've got him."
Kiran transferred Markos, the carry transition that he'd performed a dozen times in the seam network, the choreography of passing seventy kilograms of unconscious weight without dropping it or losing the neural monitoring contact. Daveth settled the meaning-reader across his back, his hands finding the position. "Copy," he said.
Kiran drew the void-blade. Didn't activate it. A drawn blade was a deterrent even without the anti-material edge, the void-skin resonated with the weapon's physics regardless of activation, broadcasting a frequency that the Abyss's deeper organisms had learned to associate with consequences.
Sato moved to point. The amber light in one hand, blade in the other, the practiced efficiency of someone who had been descending into dangerous floors since before Kiran reached Floor 50. Mira at the center, her notation device closed, both hands on the seam wall for stability in case the floor required a fast exit.
They entered Floor 272.
The three entities disengaged from the resource node in the time it took to cross the first fifteen meters.
Fast. Faster than the construct eye's degraded resolution could track as separate signatures, they became a thermal blur, the high-metabolic bodies moving through the floor's space with the directional precision of organisms that operated on a frequency the Abyss maintained at full strength up here, unattenuated by the scar tissue's dampening.
The void-skin resonated. The caretaker code pulsed at maximum output.
The entities slowed.
Not stopped. Slowed. The frequency registered as something other than prey-signature. The entities, he could resolve them now, three meters out, the construct eye's thermal imaging making shapes out of heat — were reading him the way every Abyss organism read him eventually: with the specific confusion of something encountering a biological entity that had been in the wound and returned.
Nothing in the Abyss's three-hundred-floor history had done that.
The confusion bought three seconds. Three seconds was all the fast floor crossing needed.
"Move," Sato said.
They moved. The entities circled but didn't close, the frequency keeping their targeting unsettled. Thirty meters of floor crossed in forty seconds, the group tight and fast, Sato leading with the amber light and Daveth behind her managing Markos's weight with the efficiency of a soldier who had carried injured people before and knew the mechanics.
The far seam entrance.
They hit it at a run, or the version of a run that worked in a seam entrance — cramped, single-file, the worked stone walls close on both sides. The entities reached the entrance and stopped. The seam's architecture was different from the floor — different signature, different physics, the deeper authority's construction material rather than the System's floor designation. The entities had territorial limits.
Kiran last through the entrance, blade still drawn. The entities at the boundary, motionless. The caretaker code still broadcasting.
He sheathed the blade.
"That's the last floor before the main seam junction," Sato said. She was breathing carefully, the ribs, the sprint, the management. "Two hundred meters of the main seam and we're at the corridor above Floor 265."
Two hundred meters.
He looked at Daveth. The soldier's face was unchanged by the sprint, the entities, the weight of Markos. He transferred the meaning-reader back to Kiran's shoulders. "Steady at eighteen," he said. He'd been monitoring through contact during the carry.
"Copy," Kiran said.
He started walking.
"Vorn," Sato said. She'd fallen in beside him, the amber light steady. "He's looking for the door."
"He doesn't know about the door," Kiran said.
"He knows something's down there. He's been sending units for two years. He's come down himself. People don't do that without—"
"He knows something is at the deep floors. He doesn't know what." Kiran paused. "He's looking for a reason to seal the Abyss and he hasn't found one that satisfies him yet. Tactical unit. Combat-equipped. He's not here to explore."
"He's here to destroy something," Mira said. She had her notation device out again, the researcher's compulsion to document even in a seam between dangerous floors. "He needs something to justify the sealing. Physical evidence. Data the surface governments can't ignore."
"Or a provocation," Daveth said.
The word hung in the seam's narrow acoustics.
"Something that justifies the military response he's already building," Daveth continued. "If the Abyss kills a general, the political situation at the surface changes overnight."
"He's using himself as bait," Sato said.
"Or he's genuinely looking for his son," Kiran said.
Daveth looked at him.
"Vorn's son entered the Abyss three years ago," Kiran said. "He hasn't returned. The general has been sealing himself off from that fact because acknowledging it means acknowledging that sealing the Abyss kills his own child." He paused. "If he's down here himself, something changed. He's not just looking for justification anymore."
The seam was quiet around them.
Sato's amber light moved steadily forward, one hundred and sixty meters to the main junction. The deeper authority's monitoring vibration ran through the worked stone at a frequency his pulse-rhythm integration read as passive, not proximate. The constructs were elsewhere.
"What's his son's name?" Mira asked.
"I don't know," Kiran said.
She wrote something in her notation device. He didn't ask what.
---
The main seam junction was at the top of the arterial corridor: a chamber five meters across, six meters high, where four major seams met in a crossroads that Vasik had marked as the primary navigation node for the Floor 260-280 region. The marks were elaborate here — weeks of cataloging compressed into a system of arrows and annotations that covered two full walls.
And beside Vasik's marks: new marks.
Tactical. Recent. Cut with the controlled depth of military training. Arrows with coordinates and time-stamps in a format Kiran didn't recognize but Daveth did immediately, the soldier crossed to the marks before anyone else had fully processed the chamber.
"38th's markers," Daveth said. "Standard tactical notation. They were here." He read the timestamps. "Twelve days ago. Moving down."
Down, from the junction. Toward Floor 265 and below.
"Are they still down there?" Sato asked.
Daveth read the other wall. Three separate sets of marks, overlapping, multiple trips through the junction. "Most recent: four days ago. Moving up."
Four days ago, moving up. While they were in the wound.
"They came up," Kiran said. "They were at depth and they retreated."
"Or they completed their mission and came back," Mira said.
He looked at the tactical marks. Forty-four soldiers descending to Floor 265 and returning four days ago, while he was in the wound fighting the deeper authority's constructs. What had they encountered at Floor 265? What had Vorn found?
What had he brought back?
"We're going to walk out of this seam into whatever's above Floor 265," Sato said. She wasn't asking.
"Yes," Kiran said.
Eighteen beats per minute from the body on his shoulders.
He looked at the junction marks one more time, then walked through the upward seam toward Floor 265, and whatever the surface had sent down to meet them.
