They carried Voss out of the ruined facility because none of them could agree, in the moment, on any alternative that didn't feel like becoming something they didn't want to be.
He didn't fight them. He barely seemed present at all, folded small against Vesper's supporting arm as they picked their way through the collapsing corridors, thirty years of stolen strength gone as completely as if it had never existed. By the time they emerged onto the mountainside, the facility behind them groaning through its final structural collapse, he hadn't spoken a single word.
"We can't just let him walk," Sable said, watching him with the flat, unforgiving expression of someone who had waited fifteen years for a reckoning that had just ended in something considerably messier than justice. "Sector 9. Eleven prototypes. However many field trials we don't even know about yet. He doesn't get to just survive this."
"He is surviving it," Rhea said quietly. "That's not the same as getting away with it."
"Isn't it?"
Rhea didn't have a good answer, and to her credit, she didn't pretend to.
Aiden, still unsteady on his feet from the combined Rewrite, watched the exchange from where Lyra was helping him sit against a boulder, the mountain's collapse throwing up distant clouds of ash and pulverized stone behind them. Above, the sky held its faint reddish tinge not the full fracture of before, but enough to remind all of them that whatever the Architect had gone searching for, it hadn't stopped searching.
"What do we do with him?" he asked, finally, because someone had to say it out loud.
Voss looked up at that the first real motion he'd made since the chamber and his eyes, entirely his own now, held none of the ancient patience that had filled them for thirty years. Just an old man's exhaustion, and something underneath it that might, eventually, become grief.
"Whatever you decide," he said, voice rough, unused. "I have no argument left to make against any of it. I spent thirty years believing the ends would eventually justify what I'd done to reach them. I no longer believe that. I'm not sure I believed it the moment before you separated the fragment from me, if I'm honest I think I simply didn't know how to stop by then."
"That's not an apology," Sable said.
"No," Voss agreed. "I don't think I've earned the right to offer one yet. An apology implies I understand the full weight of what I'm apologizing for. I don't. Not really. Thirty years of careful, deliberate cruelty doesn't undo itself the moment the ambition driving it gets torn out of your chest." He looked at Sable directly, meeting her fury without flinching from it. "Sector 9 deserves better than anything I could say to you right now. I know that. I don't know what would actually be enough."
Sable held his gaze for a long moment, jaw tight, and Aiden watched fifteen years of grief war visibly with the strange, unsatisfying reality of an enemy who had finally, completely lost not to justice, exactly, but to consequence.
"Nothing's enough," she said finally. "But you're going to spend whatever's left of your life finding out exactly how much isn't enough, in detail, in front of every survivor and every family who's still alive to ask you. That's not mercy, Voss. That's just the only justice actually available to us out here."
Rhea nodded slowly. "The Dominion's records on Project ARX are sealed above a classification I don't have access to anymore, given my current employment status." A tired, humorless smile. "But there are people in Neo-Arcadia who'd very much like to know the truth about Sector 9, and about eleven prototypes who never got a chance to be anything but a footnote. I think it's time they got that chance."
"You're going to expose him," Aiden said. "Publicly."
"I'm going to make sure thirty years of covered-up atrocity finally sees daylight," Rhea said. "What happens to him after that is up to people who actually lost something to it. Not to us."
Voss absorbed this without protest, some of the tension finally leaving his shoulders not relief, Aiden thought, but something closer to the specific exhaustion of someone finally set down a weight he'd carried so long he'd forgotten what walking without it felt like.
"That's fair," he said quietly. "More fair than I expected, given everything."
"Don't thank us yet," Sable said. "You're not walking away from this. You're walking into it."
They made camp that night in the shadow of the collapsed mountain, too exhausted to travel further, the four of them plus Voss and a still-unsteady Vesper settling into an uneasy silence around Sable's carefully shielded fire. Vesper sat close to the flames, staring at her own hands in the firelight like she was still adjusting to the simple fact of having them to look at.
"What happens to me now?" she asked, quietly, to no one in particular.
Lyra, sitting beside Aiden with her head resting against his shoulder, exhaustion finally catching up with her after everything the mountain had demanded, looked over with an expression Aiden recognized the same careful, protective attention she'd once turned entirely on him.
"Whatever you decide," she said. "That's the whole point of everything we just did up there. You don't have a function anymore, Vesper. You just have a choice."
"I don't know what to do with that," Vesper admitted. "Thirty years of purpose, and now I just get to pick?"
"Welcome to the club," Aiden said, managing a tired smile. "Took me a while too."
Across the fire, Rhea watched Voss with an expression that had softened, fractionally, from the cold fury of the mountainside not forgiveness, but something like the beginning of a professional's grudging respect for a man choosing, however late, to face what he'd built instead of running from it.
"You could have run," she said. "Back in the chamber, before we sealed the fracture. You had enough of the Architect's power left, for a moment, to try."
"I know," Voss said.
"Why didn't you?"
He was quiet for a long moment, staring into the fire like the answer was somewhere in the flames.
"Because Elias once told me that genuine care has no override code," he said finally. "I spent thirty years believing that was sentiment dressed up as science. Watching Lyra choose Aiden, watching Vesper choose herself, in the space of a single afternoon, undid thirty years of certainty rather more efficiently than I would have liked." A ghost of something that might once have been humor crossed his tired face. "It's difficult to keep believing something is naive once you've watched it dismantle everything you built to disprove it."
Nobody had a response to that. The fire cracked and settled, and above them, the faint red tinge in the sky held steady not worsening, not healing, just waiting, the way the Architect itself had always waited, patient beyond any single lifetime's understanding.
"It's still out there," Aiden said quietly, following everyone's gaze upward. "Somewhere. Looking for its next door."
"Then we'll be ready," Lyra said, her hand finding his in the firelight. "Together, this time. However long it takes to find it."
Rhea checked her damaged gauntlet, the compass display still faintly tracking the old pre-Eclipse signal that had first led them to Rhen's chamber, and beyond it, somewhere in the data, a faint new resonance that hadn't been there an hour ago.
"Speaking of finding things," she said slowly, studying the readout with a frown. "I think it already has an idea where to look next."
