The monitoring equipment at Floor 42 picked up the last signal from the five at 02:14.
Hartl told him at breakfast, which was the facility's cafeteria and instant coffee and Kiran sitting across from a table he wasn't eating at and Hartl sitting across from him with the data on her tablet. Five signal losses in a four-hour window between 22:00 and 02:14, spread across the floor's different sections. The monitoring equipment's thermal readings showed entity activity at critical density through the entire period.
"No recovery," Hartl said. "At this depth and entity density, recovery teams can't operate without significant risk of additional casualties."
"I know," he said.
"The facility's incident report will note the deaths as unauthorized descent casualties. The causal chain is the divers' decision to enter below their certification range."
"I know."
She set the tablet down. "I'm telling you this because you were at the entry point this morning and you went in after them. The incident report reflects what happened accurately. It doesn't assign additional causal responsibility."
He looked at his coffee. The surface facility's coffee tasted different from anything he'd had in fourteen months, which was nothing because he hadn't had coffee in fourteen months. The taste was fine. He couldn't fully engage with it.
"My being in the secondary route triggered the immune system's sealing protocol," he said. "The sealing separated the primary corridor group from the only exit route that was open."
"You couldn't have known the construction would activate in that interval."
"I knew the immune system tracks my access signature. I knew the construction response at Floor 265 was triggered by our stationary period. I knew my presence in the secondary route would eventually produce a sealing response." He looked at her steadily. "I calculated the risk as manageable and I was wrong."
Hartl was quiet for a moment. She had the expression of a person who had been in incident review boards before and was recognizing the tone of someone doing their own review process.
"What would you have done differently?" she asked.
He thought about it. The three in Floor 34's chamber, the entities orbiting them, the code holding the hesitation at thin margins. Leave them there and take the primary route? Take the primary route and hope the primary group was still at a depth he could intercept?
"I don't know," he said. "Something different."
"That's generally true of errors," Hartl said. She picked up her tablet. "The facility will need your statement for the formal report. When you're ready."
She left him with his coffee.

Mira found him in the monitoring station at ten.
She had new data — she always had new data, the facility's full array running and Mira with access to it and twenty hours since the door opened had generated a specific kind of researcher momentum that didn't stop for grief. She showed him the collection signal's output over the past twenty-four hours.
"The wound collected five new response frequencies last night," she said. "The collection signal's output at 02:14 shows a specific cluster — five signals in rapid succession, from the Floor 42 area."
He looked at the cluster. Five signals. 02:14.
"It collected their frequencies," he said.
"While they were alive. The last registered output from each was their grief architecture's response to the broadcast." She pulled the data. "The wound now has five new data points. The grief frequency of five people who heard the signal clearly enough to act on it and descended to Floor 42 in one session."
"People who died."
"People who died," she confirmed. "But before they died, the wound collected what it needed from them. Their response frequencies are in the record now." She looked at the display. "The door is learning what frequencies can sustain a descent to Floor 42. It's building toward knowing which frequency can sustain a descent all the way to the wound."
The accounting had a second entry now. Five people dead. Five data points collected. The door running its test using the people who responded to its amplified call.
He thought about this for a while.
"The door's not going to stop broadcasting," he said.
"I don't think it can," she said. "The wound's biology — once it's in a steady-state broadcast mode, that's its function. The seal from the deeper authority contained the cavity, not the broadcast frequency. The signal propagates through the geology, not through the physical architecture." She paused. "The only way to stop the broadcast is to stop the wound's biology."
"Or open the door," he said.
She looked at him.
"If the door's function is to broadcast grief frequencies and collect responses and test until it finds the right match — the broadcast ends when the door achieves its purpose. When it opens for the frequency that completes whatever the wound is trying to do."
"We don't know what it's trying to do."
"No," he said. "But we know what it promised."
*At the bottom there is a door. Behind the door is everything you've ever lost.*
The broadcast would keep running. The people with the right grief architecture would keep responding. The test would keep running until the door found what it was looking for, or until the wound's biology was stopped — and the wound was the Abyss's deepest biology, eleven thousand years old, and the deepest authority's construction hadn't stopped it.
The door was patient. It had been patient for eleven thousand years.
He closed the monitor display.

Daveth was at the entry shaft at noon.
Not monitoring — he'd been there since nine, running a quiet but persistent intervention with the people who showed up at the line. Not the official warning that Kiran had given the previous day. Something different: Daveth talking to people one at a time, the casual conversation that looked like nothing but was actually delivering specific operational information. Floor by floor, what to expect, what would kill you, what could be prepared for. Not "don't go." "Go prepared."
Three people at the shaft had packs with actual supplies. Water, emergency beacons, basic medical kits. Descent appropriate clothing.
"The three with packs," Kiran said.
"Two certified divers who should know better, one civilian who is a better listener than average." Daveth looked at the shaft. "I can't stop them and neither can you. What I can do is make it slightly less likely they die in the first twenty floors."
"The five last night—"
"The five last night would have gone in regardless," Daveth said. "With better preparation they might have made it further before the entity activity caught them. Might have had time to make a better decision about when to turn back." He looked at Kiran. "Or they wouldn't. The grief that strong doesn't respond well to calculus. But the preparation wasn't on the table because you had three days and a warning from the first person who survived Floor 237."
The first person who survived Floor 237. The framing landed wrong — he'd survived everything below 237, currently Floor 265, not through any particular virtue but through the specific combination of preparation, adaptation, and the Abyss's biology doing things he still didn't fully understand.
"I'm not the template," he said.
"No," Daveth agreed. "You're the data point. And the data point is: months of preparation, specific biological adaptation, continuous calibration of risk against the mission. The data point says it's possible to survive at depth." He paused. "What it doesn't say is whether it's worth it."
Kiran looked at him.
"You've been in the Abyss for fourteen months," Daveth said. "You touched the door once for thirty seconds. You're not back down there yet." He said it without judgment, which was why it landed harder than judgment would have. "That's not a criticism. You needed to come up for what you needed up here. I know that."
"But."
"But you know what comes next and I know what comes next and the five last night went before you could stop them." He looked at the shaft entrance. "Every day you're up here is another data set for the wound. More frequencies tested. More deaths." He paused. "I'm not telling you to rush."
"You're telling me the cost of waiting is measured in other people's lives."
"Yes," Daveth said. "That's what I'm telling you."

Osei called him to the medical bay at fourteen hundred.
Markos's parietal neurons had done something new.
She showed him on the readout — the firing pattern, the islands in their adapted rhythm, and then, for thirty seconds at 12:47, a burst of coordinated activity that was different from the steady synchronization. Not the wound's rhythm. Something else, multiple islands firing in a complex sequence that she hadn't seen before.
"Duration?" he asked.
"Thirty seconds. Seventeen separate firing events within the burst. The sequence pattern is not random — the intervals between events are structured." She pulled the burst's waveform up separately. "Whatever this is, it's organized."
He looked at the waveform. The structured intervals. The multiple islands coordinating in a sequence that had internal logic.
"Did it correspond to any external event?" he asked.
She pulled the timeline. "12:47. The facility's monitoring array registered a new response event at 12:48 — someone at the surface entry point with a high-amplitude grief frequency. The collection signal had a pulse." She looked at him. "The burst preceded the external event by one minute."
The parietal neurons had fired in a complex sequence. Then the wound had received a new response frequency.
"He anticipated it," Kiran said.
"Or the wound communicated to him through the tissue integration before the external signal was detectable by our equipment," she said. "The tissue is still integrated. The wound's biology, at long range, may be transmitting information that the parietal neurons are processing."
Markos. The meaning-reader. The person who could see the wound's letters in the biology of the floors. Still alive at thirteen beats per minute by the wound's grace, his damaged brain running an adapted rhythm on the tissue's timing.
The wound was still talking to him. Markos was still reading it.
"What did the sequence mean?" Osei asked.
"I don't know how to read it," he said. "I can't translate the firing pattern."
"Could someone?"
He thought about that. The meaning-reader's function — the ability to perceive the wound's communication in the biology of the floors. He'd been using Markos's interpretation throughout the descent. Now Markos was the medium and the message was in his own neural architecture.
"I need to get him back into the wound's proximity," he said.
"He's medically stable," Osei said. "Transport is technically feasible. It is not—"
"Safe," he finished. "I know."
She looked at him. The same flat honesty she'd been applying since Floor 265.
"Tell me when the next burst happens," he said.

He was at the entry shaft again at eighteen hundred when Daveth came to stand beside him.
The line was shorter than the previous day. Eight people instead of thirty. The forty-three unauthorized entries and the five deaths had been reported in the facility's official notices, and some portion of the people who'd been considering descent had reconsidered. Not all. Eight were still there, in the facility's pale late-day light, looking at the shaft with the specific attention of people whose grief was strong enough to survive the math of yesterday's casualties.
"Hartl is meeting with Mira and Vorn at twenty-hundred," Daveth said. "The facility's position on the broadcast and the access restriction. The incident report."
"I'll be there," Kiran said.
"You should know before the meeting—" Daveth paused. "The five this morning."
"Yesterday," Kiran said.
"The five yesterday. The Dive Authority's casualty records matched three of them to the psychological intake database. All three had experienced bereavement within the last two years. Significant loss — child, partner, parent." He let that settle. "The other two are unidentified. No intake records. They didn't go through any formal channel."
Five people who had walked into the entry corridor because the wound's amplified broadcast had found their grief frequency and activated the specific mechanism that overrode the survival calculus. The same mechanism that had been running in Kiran for fourteen months.
"The broadcast is going to keep finding people like that," he said.
"Yes," Daveth said.
"And I'm the one who amplified it."
Daveth didn't argue the causal chain. He was a tactician and tacticians didn't argue facts.
"What I can do," Kiran said, "is get to the door before it tests another hundred people." He looked at the shaft. "The wound has my access signature. Mira said the next contact will be easier than the first." He paused. "I need two days. The surface has what I need — Mira's data, the monitoring records, Markos's baseline, information about the floors I couldn't gather from inside them."
"Two days," Daveth said.
"Then we go back in."
Daveth looked at the eight people in the line. At the shaft entrance. At the bioluminescent light visible at the bottom of the first corridor step.
"Tell me the morning before we go," he said. "I'll have equipment ready."
He was already going in. Kiran had known that since the secondary route, since the entity chamber, since the long careful walk out with three people who wouldn't have made it without the code. Daveth had signed on for this at depth greater than anyone besides Kiran had survived, and he hadn't stopped since.
"All right," Kiran said.
The eight people in the line were still there.
The wound's broadcast ran through the shaft and up through the facility's concrete and up through the geology of the site and out across the city to find every grief frequency that was strong enough and close enough to respond.
Seven of the eight went in before nightfall.
He watched them go.
