Zeph cut a piece of the ship and it didn't hurt.
That was the part that surprised her. She'd spent weeks learning the warship's moods through the bio-tissue, feeling it grieve in the wreckage field, feeling it want to investigate the signal from Kaelen's dead ship, feeling it warm and cold and alert and resting. The ship was alive. Cutting it should have hurt.
Instead, the copper growth in the lower decks separated cleanly when Zeph guided the process through her interface. A section of new bio-tissue the size of a dinner table, complete with its own atmospheric processing nodes and thermal regulation pathways. The ship didn't flinch. The separation was biological, not surgical, the ancient vessel budding off a piece of itself the way a plant sends out a runner. The remaining tissue at the cut edge was already regrowing before Zeph had the separated module wrapped in a containment field for transport.
"She wanted to do it," Zeph told Voss as they loaded the module into the transport pod. "The ship. When I showed her what we needed, the tissue configured itself for separation before I even started the process. She knew what we were trying to do."
"The Progenitors designed these vessels to support subsidiary installations," Voss said. "Colony ships. Fleet tenders. The ability to bud off functional biological modules is probably standard for the class."
"It's not standard. It's generous." Zeph put her hand on the module. The copper bio-tissue pulsed under her palm, warm and active, a living piece of the warship that was now independent, carrying enough biological processing capacity to sustain a settlement's atmosphere for months. "She gave us a piece of herself."
"Anthropomorphizing, child."
"She gave us a piece of herself, Doctor. I felt it. She did it on purpose."
They brought the module down to Ember Point on the next pod run. The settlement's engineers were waiting: three men and two women in worn mining coveralls, hands calloused from fourteen months of improvised maintenance, faces carrying the particular watchfulness of people who had learned that their survival depended on one exhausted twenty-two-year-old and who were desperate for a backup plan.
The lead engineer was a woman named Pratt. Short, stocky, with a prosthetic knee that clicked when she walked. She looked at the copper bio-tissue module the way a mechanic looks at an unfamiliar engine: with interest, suspicion, and the immediate desire to take it apart.
"Don't take it apart," Zeph said.
"Wasn't going to." Pratt was already crouching beside it, her non-prosthetic knee on the bio-tissue floor, studying the module's surface. "How does it connect to our existing network?"
"Contact interface. The module's tissue will bond with the settlement's bio-tissue on physical contact. The two systems will merge and the module's atmospheric processing will integrate with the existing network." Zeph placed the module against the wall of the main corridor, where the settlement's bio-tissue was thickest. The copper tissue touched the amber growth. For three seconds, nothing happened. Then the edges softened, the two biological materials reaching toward each other, testing compatibility, exchanging chemical signals.
The bond formed. The module's copper tissue flushed amber as it integrated with the settlement's network, the warship's biological material adapting its frequency to match the local system. Within a minute, the module was indistinguishable from the surrounding growth, a new organ in the settlement's living infrastructure.
"Atmospheric processing capacity just increased by thirty-one percent," Aria-7 reported through the settlement's newly enhanced communication system. "The module is functioning within normal parameters. It will maintain current atmospheric conditions indefinitely without active void-touched management."
Pratt's clicking knee popped as she stood. "Indefinitely."
"Barring physical damage or catastrophic dimensional disruption. The module is self-sustaining."
Pratt looked at Zeph. At the copper bio-tissue on the walls. At the ceiling where the warship's gift had already started extending tendrils into sections of the habitat that the original growth hadn't reached. "Fourteen months," she said. "Fourteen months of watching Niko kill himself keeping us breathing. And you just stuck a piece of your ship to our wall and fixed it."
"Not fixed," Zeph said. "Supplemented. The existing system is still primary. This is backup. But yeah, Niko can take his hands off the floor now and the air will keep coming."
Pratt's face did something complicated. The expression of a person processing relief and resentment simultaneously, grateful for the help and furious that it had taken this long and arrived in this form. She turned and walked down the corridor to tell the other engineers, her prosthetic knee clicking on the bio-tissue floor.

Sable found Niko still in the control room, hands on the floor, eyes closed.
"You can stop," she said from the doorway. "The module is integrated. The settlement's atmospheric processing will run on its own."
Niko didn't open his eyes. "I know. I felt it connect. The new tissue is... louder than ours. Stronger. Your ship grew it recently, yeah? In the Expanse?"
"In the last day or so. The ship's been growing new tissue since we entered."
"It's healthier than what I've been working with. The bio-tissue here came from wreckage. Dead material that Niko Rohn, idiot miner, woke up by touching it at the wrong time. It's been alive for fourteen months but it started dead. Your ship's growth started alive. The difference is..." He trailed off. His hands shifted on the floor. Then, slowly, he lifted them.
The settlement's pulse didn't change. The atmospheric systems kept running. The lights stayed on. For the first time in eight months, Niko Rohn took his hands off the floor and the world didn't end.
He opened his eyes. The amber irises found Sable in the doorway.
"Stars," he said. "That's what it feels like to stop."
Sable walked into the room and sat down beside him on the bio-tissue floor. She put her own hand on the living surface, the communication layer opening at passive depth, the settlement's systems registering through her perception as a smaller, rougher version of the warship's architecture. Functional. Alive. But cruder, like a shelter built from found materials rather than designed.
"How did you learn?" she asked. "To interface with it. Nobody taught you."
"Nobody teaches miners to read alien biology." Niko pulled his knees up to his chest. He was even thinner than he'd looked seated, the bones of his wrists sharp through the skin, the silver streaks in his hair catching the bio-tissue light. "When the Expanse hit, everything died. I'd been poking at the bio-tissue from the wreckage for weeks before that. Just touching it. It felt warm, and warm things underground usually mean geothermal, which means money, so the company had us excavating it. I was the only one who could feel it was alive."
"Because you're void-touched."
"I didn't know that word. I just knew the stuff talked to me when I touched it. Not words. Feelings. Like touching a sleeping animal and feeling it breathe." He looked at his hands. The amber veins visible under the pale skin. "When the power died and the air started running out, I grabbed the biggest piece of bio-tissue in the excavation and just... pushed. I don't know how else to describe it. I pushed everything I had into the tissue and told it to breathe for us."
"And it did."
"It did. It grew through the walls in the first hour. Took over the atmospheric systems in three. Power generation by the end of the first day. It was hungry, the tissue. Starving. Dead for ten thousand years and suddenly alive again, and it wanted to grow. I just had to keep it pointed in the right direction."
Sable listened. Not just to the words. Through the communication layer, she could feel Niko's interface with the settlement's bio-tissue. It was different from hers. Where Sable's connection to the warship was about communication, about the flow of information and signal, Niko's connection was about maintenance. About keeping systems running. About the steady, patient work of sustaining a living infrastructure day after day after day.
"Describe what you do," Sable said. "When you're connected. What does it feel like?"
Niko thought about it. "Like holding something together. You know when you're carrying too many things and your arms are full and you can't put anything down because everything will fall? That. But for fourteen months. Every system in the settlement, every atmospheric pump and thermal regulator and water recycler, all of them running through the bio-tissue, all of them needing input, needing adjustments, needing someone to keep their hand on the wheel."
"You sustain."
"I keep things running. That's all I know how to do. I can't pilot. I can't do what your ship's pilot does. I tried once, early on, to use the bio-tissue for navigation when we were trying to send a distress signal through the Expanse. Couldn't do it. The piloting frequency is different from what I do. But keeping things alive, keeping systems stable, holding an infrastructure together without letting it drift or degrade?" He smiled. Thin. Tired. "I'm really good at that."
Sable's hand pressed harder into the floor. The communication layer deepened. She was thinking about Kaelen. The Progenitor pilot in the dead ship's Throne. The one who had sat alone for centuries, maintaining the containment signal, holding one piece of the seal in place while the other four ships were destroyed. Kaelen hadn't been a combat pilot. Kaelen had been a maintenance specialist. A sustainment operator. The pilot whose job was not to fly but to hold, to maintain, to endure.
Five ships. Five pilots. Five roles. The combat pilots handled the crisis. The communication pilot managed the signal. The power specialist ran the drive. And the sustainment pilot sat in the Throne and kept it all together, hour after hour, year after year, for as long as the seal needed holding.
"Niko," Sable said. "The entity at the center of the Expanse. The thing that's sealed. The seal is a Progenitor Throne, like the chair in the dead ship we found. One pilot sat in it for three hundred years, maintaining the containment. She died because the load was too much for one person."
"Kaelen," Niko said.
Sable stared at him.
"The settlement's bio-tissue carries echoes," he said. "From the wreckage it came from. I've heard the name in the tissue's memory. Kaelen. The one who stayed."
"You heard her through the bio-tissue."
"Fragments. Old ones. Like reading a letter that's been folded and unfolded so many times the creases have worn through. She was... she was like me. She held things together. That was her function. Not fighting, not flying. Holding."
Sable took her hand off the floor. Looked at Niko. At the amber eyes and the silver hair and the veins traced in bio-tissue gold and the exhaustion that went so deep it had become part of his face.
"Niko. The weapon we're building to destroy the entity. It needs five operators. But the Void Throne at the center of the seal also needs someone to maintain the containment during the operation. If the seal fails during the Severance firing, everything falls apart."
"You need someone to hold the seal while you fire the weapon."
"We need someone who can sustain a Progenitor system under load for three to five minutes without the system degrading. Someone built for endurance. Someone who can hold."
Niko looked at his hands. At the veins. At the floor beneath him, the bio-tissue that he'd been sustaining for fourteen months, the living infrastructure that had kept fifty-three people breathing.
"I can hold things," he said.

"Captain." Aria-7's voice cut through the settlement's comm system, fed from the warship in orbit. "The ISV *Mandate*'s drive signature has increased. Commander Kaine has restored partial function to his secondary drive unit. Current speed: sixty-two percent of pre-damage capacity. At the current rate, the *Mandate* will reach the Delacroix system in approximately four hours."
Kira was in the settlement's common area, reviewing the Severance data with Voss on a portable display. She looked up.
"He repaired the drive."
"Partially. The primary damage to the aft housing remains. But the secondary unit has been brought back to limited function. His engineers are competent."
Cross was beside her, the tactical display showing Kaine's position relative to the Delacroix system. "We have been stationary for ninety minutes. The time advantage we gained from damaging his ship is eroding. Every additional minute at Ember Point costs us."
"I know." Kira stood. Looked at the settlement's common area, the miners and families at their tables, the children playing in a corner where the bio-tissue floor was softest. Fifty-three people who had been trapped for fourteen months and who were about to watch a warship leave them behind. "How long to get the life support module fully integrated?"
"Zeph reports the module is operational. The settlement's atmospheric processing is running independently of Niko's interface."
"Then we go." Kira walked toward the control room. "I need Tessa Rohn's answer. Now."
She found Tessa in the corridor outside the control room, leaning against the bio-tissue wall with her arms crossed and her mining boots planted. Watching the control room door. Listening to whatever was happening inside.
"Time's up," Kira said.
Tessa didn't move. "I heard your AI. The ship that's chasing you."
"An Imperial interceptor. Damaged but functional. Four hours out. We need to be gone."
"And you want my brother."
"I need your brother. What he can do, his ability to sustain Progenitor systems under load, that's not something I can get from anyone else on my crew. We have a pilot, a communication specialist, and a power specialist. We don't have a sustainment operator. Niko is that."
Tessa looked at the control room door. Behind it, her brother was talking to Sable about a dead Progenitor pilot named Kaelen who had held a seal together for three centuries and died in the chair.
"He'll say yes," Tessa said. "He's already decided. I can tell by his voice. He gets this sound when he's made up his mind, like his throat tightens and his words get shorter. He's had it since he was a kid. Used to do it before jumping off the mine scaffolding."
"And you?"
Tessa pushed off the wall. Stood straight. She was shorter than Kira by three inches but the way she held herself erased the difference.
"Niko goes, I go. That's not a request. That's not a negotiation. My brother has kept fifty-three people alive for fourteen months because I asked him to, because I was the one who told him to try when the lights went out, because I put that on him and he carried it and it nearly killed him. I am not sending him to the center of the Shattered Expanse to help strangers fire a weapon without me standing in the room."
"You're not void-touched. You can't participate in the operation."
"I don't need to participate. I need to be there. When he's sitting in whatever alien chair you're putting him in, running whatever alien system you need him to run, exhausting himself for strangers the way he's been exhausting himself for family, I will be in the room. That's my condition."
Kira looked at Tessa Rohn. At the hard face. The short hair. The mining boots on the bio-tissue floor. A woman who had run a settlement inside collapsed spacetime for over a year and was now bargaining for the right to stand next to her brother while he did something impossible.
"Agreed," Kira said. "Both of you. Get your things. We leave in twenty minutes."
Tessa turned and opened the control room door. Inside, Niko was still sitting on the floor, his hands resting on his knees for the first time in months, his amber eyes looking up at his sister.
"I'm going," he said.
"I know." Tessa held out her hand. "Get up. We're leaving."
Niko took her hand and stood. His legs shook. Fourteen months of sitting on a floor, keeping a world alive, and his legs had to remember what standing felt like. Tessa held his arm until the shaking stopped.
They walked out of the control room together. Past the common area where the miners watched them go. Past Pratt and her clicking knee and the other engineers who had learned to keep their settlement running on alien biology. Past the children in the corner who had never known a world that wasn't wrapped in living tissue.
Niko paused at the airlock. Looked back at the corridor. At the amber walls. At the settlement that had been his responsibility and his prison and his reason for getting up every morning for fourteen months.
"Take care of her," he said to the walls.
The bio-tissue pulsed. The warship's gifted module, now integrated into the settlement's network, ran the atmospheric systems with the steady patience of a machine that had been designed to keep things alive without needing to be asked.
Then they sealed the suits and walked across fifty meters of rock to the transport pod, and the settlement shrank behind them, and the warship grew ahead of them, and Niko Rohn heard her singing louder with every step.
