Jin found the signal at 0613.
Not CSD's signalâthe absence of something that should have been there. The camp's perimeter had two relay points, the transmitters that Jin had assembled from salvage that Sev had sourced before Sev's death in the station fight. The relay points bounced the camp's communication signals through a series of low-power hops that made the signal harder to trace to its origin. The hopping was Jin's design. It worked well.
It had been working well until the CSD frequency sweep Jin had been monitoring through the night had run across one of the relay points at 0550 and the relay point hadn't known to be quiet.
The relay point was a machine. Machines didn't know when to be quiet. They broadcast because broadcasting was their function. Jin had built the relay points with the components available and the components hadn't included the counter-detection protocols that the relay points needed and that Jin hadn't had time to add before the mission started.
"The sweep identified the general signal origin area," Jin said. The third floor of the abandoned building, the equipment spread across the floor, the displays showing the frequency data that the overnight monitoring had accumulated. "Not the specific building. But the area. The area is about six blocks. We're in the area."
Kael, beside Jin: "How long before they narrow it."
"Active sweep team, six-block area, looking for active transmittersâ" Jin's hands on the scanner. The calculation running. "If they've already deployed: two, maybe three hours. If they're deploying from the Warren's existing positions, longer because they have to move the sweep team and the sweep team's been doing re-extractions all night." A pause. "I'd say two hours to be safe."
"We have maybe one water redistribution left in two hours' worth of rations," Kael said. The statement of a logistics problem that the building's population had been managing for twenty hours. "For three hundred and nineteen people."
"I know." Jin looked at the displays and the displays showed the frequency data and the frequency data showed a search closing around a building that held three hundred and nineteen people who had nowhere else to go.

The meeting was Kael and Deshi and Hana and Viktor and Zara and Cross. Viktor seated, the physical state unchangedâthe splints, the wired jaw, the bruising that had progressed from angry red to the deeper colors that healing producedâbut the eyes sharp, the tactical mind working at full operational capacity despite everything below the neck.
Zara put the situation plainly: "Two hours. We move everyone out."
"Where," Deshi said. The administrator's question. *Where* was the category of question that the lower city's geography answered badly. The camp had been possible because the abandoned commercial district had available structures. The available structures in the lower city were systematically occupiedâby the displaced, by the hollow, by the informal settlements that had been there before the Cull and that the Cull had depopulated in ways that made the post-Cull occupation complicated.
"We don't move everyone together," Zara said. "We're three hundred and nineteen people. Three hundred and nineteen people moving through the lower city produces a signal that a different kind of sweep finds. We break into groups of six to ten. Each group has a destination. Each destination is different."
"You have destination coordinates for thirty-one groups of ten."
"I have eight," Zara said. "Eight shelter points that Mercy's network mapped before the Underground was compromised. Each of those points can hold forty to fifty people." She looked at Deshi. "I need you to help me figure out how to route the remaining hundred and forty people who don't fit into eight groups of forty."
Deshi looked at the maps that Zara had laid outâpaper, the physical copies that Mercy's network had maintained alongside the digital versions, the physical copies that survived electromagnetic interference and scanner detection and the destruction of the devices that held the digital versions. Deshi studied the maps for two minutes without speaking.
"The market district," Deshi said. "Southwest of the Warren. There are storage facilities that the flood management authority decommissioned eight years ago. I administered the decommissioning. I know the interior layout." She pointed to the maps. "Two hundred and forty people between the eight shelter points and the storage facilities. The remaining seventy-nine needâ" She studied. "The mid-tier service corridors. The ones that connect the lower city to the Shelf from below. They're not designed for habitation, butâ"
"Habitation isn't the requirement," Zara said. "Shelter for six to eight hours. Long enough for the CSD sweep to move through and look for an active signal that won't be there. Then reassemble."
"Where."
The question that the question before it had been building to. Where did three hundred and nineteen displaced people reassemble after they'd scattered through the lower city's emergency shelter network. Where was the point around which the dispersal gathered when the dispersal's need to gather was itself a signal that the sweep could find.
"I need to talk to Mercy," Zara said.
The room looked at her. Viktor's eyes: present, reading. Kael: neutral, the fighter's face that held conclusions until they were ready. Deshi: the administrator, calculating whether the answer Zara was giving was actually an answer or a deferral.
"Mercy's been off-grid since the Underground was compromised," Kael said. "His network is how we knew the shelter points. His network is how information moves in this city. If Mercy goes off-grid, his networkâ"
"His network doesn't go off-grid just because Mercy does," Zara said. "His network is the lower city. It's the people who've been running information in these streets for thirty years. Mercy goes quiet, the network goes quiet. Mercy comes back, the network comes back." She looked at the maps. At the shelter points. At the storage facilities. "I need him to come back."
No one had a better plan.

Viktor moved. Badlyâthe splints prevented the full use of his hands, the wired jaw had shifted some indefinable weight in his posture that the healing required he not correct, the bruising over his ribs made deep breaths expensive. But he moved. From his seat to the doorway, refusing the help that three people offered. Moving was how Viktor established what the body could do. If it could do this, it could do more than this.
He found Cross in the medical area. Sitting where she'd been sitting when Zara had sat beside her the previous eveningâthe same wall, the empty slim case on the floor beside her, the researcher's particular stillness that wasn't the stillness of rest but the stillness of a mind working faster than the body could represent.
Cross looked at him. The assessment: his physical state, the splints, the jaw. The brown eyes holding their clinical quality and the thing beneath it.
"Tell me what you didn't tell Zara," Viktor said. Through the wired jaw, each word shaped with care.
Cross studied him for a moment. Reading him. "What makes you think I didn't tell her everything."
"She's angry at you." He moved to the wall opposite Cross and put his back against it. The standing position was better than sittingâthe ribs tolerated it more. "Controlled angry. She does that. Puts the anger somewhere until the situation allows it." He looked at Cross. "You told her something in the shaft that changed the category you're in. You're not an ally with complicated motivations now. You're something with a debt."
"Yes," Cross said.
"What else is in that debt that she doesn't know about."
Cross was quiet. The deliberation of someone who'd made one disclosure and who was managing the question of how many more the situation required. Then: "The ANCHOR-7 seed. The memory preservation architecture. I told her I built it to protect the memories that the erasure was designed to remove."
"Yes."
"I didn't tell her that the seed was also designed with a recovery mechanism. A system thatâgiven the right catalyst and the right conditionsâcould attempt to retrieve not just the preserved fragments but the content of the erasure itself. The memories that the standard erasure protocol removed and that the ANCHOR-7 seed archived in a state that is technically recoverable."
Viktor processed this. His hands at his sidesâthe splints preventing the grip that the information would have sent his hands toward. "She can get her memories back."
"Some of them. The recovery is imperfect. The archived content is compressed, degraded by the erasure process, stored in a format that the seed maintains but that the translation back into functional memoryâthe actual experience of remembering rather than having a data recordâis uncertain. The catalyst compound that her body produced: it was the first component. The reversal it performed on the Warren's buffer units was the compound's secondary function." Cross looked at the empty case. "Its primary function, the function I designed it for, was to prime the seed's recovery architecture. The compound is gone. Used. But the priming may have initiated the first stage of the recovery sequence."
Viktor looked at her. "She's going to start remembering."
"She may start retrieving fragments that are more complete than what she's experienced so far. More coherent. Moreâ" Cross paused. "The memories the erasure was designed to remove were the operational ones. The Ghost program's most sensitive records. The operations she performed. The people she met at the program's highest levels. If those memories begin returning, the content will beâdifficult."
"She killed people."
"Forty-seven confirmed operations. The program's records indicate the targets were high-value. The people she's going to remember being, if the recovery proceedsâthat person did things that the person she is now would not do."
Viktor's jaw tightened. Through the wiring. "Tell her."
"She has enoughâ"
"Tell her." He knew what it was like to have someone decide for you what you could handle. "She'll find out regardless. The memories will come. If you tell her, she can prepare. If you don't, she walks into it blind." He looked at Cross. Gray eyes to brown. "You've been deciding what she can handle since before she knew you existed. That's done now."
Cross held his eyes for a moment. Then looked away.
"Yes," she said. "It is."

The evacuation began at 0800. Kael coordinated the groups: six to ten people, staggered departures at three-minute intervals, different routes to different destinations. The former Warren administrator Deshi moved with the largest group toward the decommissioned storage facilities, the one person whose knowledge of the facility made the group functional rather than merely large. Hana stayed with Viktor for the medical transit, the two of them moving more slowly than the other groups, the route adjusted for Viktor's pace.
By 0900, the building was empty.
Zara stood in the abandoned commercial building's main floor for the thirty seconds between the last group's departure and her own. The floor where three hundred and nineteen people had been sleeping, eating from inadequate supplies, waiting for news from a mission in the mid-tiers. The marks of occupation: the indentations in the salvage bedding that bodies leave, the distribution of food wrappers and water containers that the rations had produced, the marks on the walls where children had leaned and adults had sat.
The Underground had been the pits. Before the pits it had been other thingsâMercy's network, the runners, the informal systems the lower city built to hold itself together below the level CSD bothered to look. The pits were one expression of it. This building was another.
The Underground was not a place. It had never been a place. It was the people and their knowledge of each other and the systems they'd built for exactly this: surviving the thing that was trying to make them not survive.
The building was empty. The Underground wasn't gone.
She walked out into the lower city's morning.
Jin's voice on the comms: "CSD sweep found the relay point location. They're moving into the area now." A pause. "Building's clear, right?"
"Clear," she said.
"Good." Another pause. The kind that Jin used when there was something else. "I've been monitoring the Warren's frequency traffic. The re-extraction teams stopped at midnight. Seventeen hundred and forty-three re-extractions total. That's the final count." A breath. Not the technical pauseâthe pause of someone delivering a final number and feeling the number. "Three thousand and forty-three people in the Warren have their memories back right now. Three thousand and forty-three. That's the thing we did."
Zara walked. The lower city around her. The streets that had been her streets for two years, the geography she knew the way Zero knew itâthe exits, the sight lines, the threat gradients. The streets she'd known before that as Specter, in whatever fragments the recovery had begun to surface.
The ANCHOR's seed pulsed. Once. The rhythm slightly different from its baselineâthe priming that Cross had described, the recovery architecture beginning its uncertain work.
*A room. Bright. Not the clean white of the program's conditioning spacesâsomething else. Warm white. The smell ofâ*
Gone before it resolved. Too brief to hold. The seed had found something in the archives and lost it before it became memory.
But it had been warm.
She kept walking.
