The settlement's med bay had two cots and a shelf of containers Ark couldn't read the labels on. Sera had commandeered one cot, both supply kits, and most of the available floor space. Jace was on the cot. He wasn't moving.
"I need everyone out," Sera said.
Nobody moved.
"That wasn't a request."
Ark stepped back toward the doorway. Dex followed. Rook stayed exactly where he was, arms crossed, cracked shield stowed on his back.
Sera looked at him.
Rook looked back.
"Two meters," she said. "Against the wall."
He moved two meters. Against the wall.
Ark watched through the gap in the doorframe. Sera's threads extended from her fingertips, pale gold in the low light, and sank into Jace's chest. She exhaled slowly. Her eyes went unfocused in the way they did when she was reading deep.
Three minutes passed.
"He's stable," she said, not looking up. "The Blade Dancer class is still active. It shouldn't be."
"Is that good?" Ark asked through the gap.
"I don't know yet. Stop talking."
He stopped talking.
The settlement's ambient hum filled the silence. Lira was somewhere outside running readings on the containment equipment. Mira had taken a perimeter position. Kira was still mobile despite the arm, which Ark wasn't sure whether to admire or worry about. Pel had stayed at the doorway long enough to confirm Jace's vitals on his own equipment, then wandered off to look at the settlement's power systems.
Ark's system notification tray had been quiet since the containment burst. A single yellow alert sat unread: *Class architecture monitoring: external frequency detected in Blade Dancer matrix. Status: undefined.*
He'd been staring at it since they dragged Jace out of the energy field.
Forty minutes later, Sera sat back on her heels.
"Okay," she said. "Here's what I've got."
Rook moved forward. Ark came in from the doorway.
"The corruption is embedded in the Blade Dancer class structure. Not surface level. It's in the foundational parameters." She held up a hand before anyone could speak. "It's not destroying anything. Not yet. The way normal Void corruption works, it degrades class architecture, eats through the energy pathways, rewrites outputs until nothing functions. This isn't doing that."
"What is it doing?" Ark asked.
"Integrating." She pulled her threads back. "It's behaving the way your corridor integration is behaving, Ark. The corruption strain the settlement engineered, it had controlled patterns. Rules. It wasn't wild Void. It was domesticated, if that makes sense. Blade Dancer is treating it like a new operational parameter instead of an attack."
"That's good."
"Maybe. The integration could complete and become a stable part of his class. Or—" She hesitated. "Or the matrix could reject it. Not immediately. Could take days, could take a week. If it rejects, the corruption goes from integrated to active, and it burns through Blade Dancer from the inside."
"Fifty-fifty," Rook said.
Sera looked at him. "Pretty much."
Ark pulled up Jace's status in his system overlay. The Blade Dancer class showed a yellow flag, not red, not green. *Modification in progress. Integration status: 34%.*
He hadn't seen that status on another person's class before. He wasn't sure he was supposed to be able to see it.
"When he wakes up," Sera said, "he's going to feel it. Don't let him panic."
"Jace doesn't panic," Dex said from the doorway.
"Jace deflects. Which means he'll make jokes about it until he stops." She stood, stretched her back. "The silence is the problem. Watch for the silence."

Jace woke up at hour three.
He opened his eyes, blinked at the ceiling, and then very carefully held up one hand and stared at it.
"Huh," he said.
"Hey." Ark pulled his chair closer. "How do you feel?"
"Like I got hit by a controlled Void burst in an experimental dimensional settlement." Jace dropped his hand to the cot. "So. Average Tuesday." He paused. "It's not Tuesday, is it."
"Day 140."
"Right." Another pause. "There's something in the Blade Dancer class."
"Yeah."
"I can feel it." He said it carefully, like he was checking whether the words were going to break something. "It's like... you know when you've been running a class for months and it starts running quiet? You stop noticing it? Blade Dancer went quiet a long time ago. Now it's loud again. But it's not the same sound."
Ark thought about his own system architecture. The corridor integration. The way the frequencies had started threading through structures that used to run independently.
"Different isn't automatically bad," he said.
"Man, that is either the most reassuring thing you've said to me or the least." Jace sat up slowly. Rook, still against the wall, watched without moving. "Sera explained it?"
"She did."
"Fifty-fifty." He looked at his hands again. Both hands this time. "Great. Now stabby has a goth phase." He said it lightly, and his hands were shaking.
Sera came back in. She looked at his hands. He noticed her looking. He put them flat on his knees.
"Can I move?" he asked.
"Slowly."
He swung his legs off the cot. Ark watched the Blade Dancer status in his overlay. Still 34%, still yellow. No change from the movement.
"Does it feel different when you call the class?" Sera asked.
Jace closed his eyes. The air around his right hand shifted, not quite the silver-edge sharpness that Blade Dancer usually produced. Darker. Denser. The blade that materialized had the same shape but the light it caught was wrong. It absorbed light at the edges instead of reflecting it.
"Yeah," he said. "It feels different."
He dissolved the blade. The air normalized.
"I want readings every four hours," Sera said. "And I want to know immediately if the sensation changes."
"Yes, boss."
"I mean it, Jace."
"I know." He looked up at her. No deflection. "I know you do."

Lira found Ark outside an hour later.
She was running a portable analyzer across the settlement's outer containment architecture, the same framework that had failed, now cold and inactive. Ark had come outside to give his system a few minutes without monitoring, which was a thing he'd started doing since the cascade event. The quiet helped.
"I have something," Lira said.
"Good something or bad something?"
She turned the analyzer screen toward him.
The readings meant nothing to Ark on their own. But the frequency display in the corner showed two layered signatures. One he recognized: the corruption strain the settlement had used, the controlled pattern, the domesticated Void. The other signature sat underneath it like a foundation.
"I've been analyzing Jace's corruption readings against the settlement's original containment design," Lira said. "The controlled strain has an embedded architecture underneath. Something the settlement didn't engineer. Something they built around."
Ark looked at the second frequency. He recognized it the way he'd learned to recognize the corridor's resonance. Not identical. But related.
"Architect frequency," he said.
Lira nodded. "The settlement has been managing this corruption technique for generations. But they didn't invent it." She lowered the analyzer. "Someone gave it to them. Taught them the containment patterns. The base architecture of every stability measure they used traces back to this frequency."
"An Architect taught the settlement how to manage Void corruption."
"Yes." She looked at the dormant containment framework. "Which means someone has been actively working in the interstitial spaces for a very long time. Long before Prometheus. Long before the Awakening."
Ark stared at the second frequency on the analyzer screen.
The corridor hummed around him. Distant and constant and patient.
An Architect had been here. Teaching. Building relationships with isolated communities in the gaps between zones.
Not sleeping. Not extinct.
Working.
"We need to tell the others," he said.
"Yes," Lira said. "We do."
---
The briefing happened in the settlement's central space. Whatever it had been before, it was a meeting room now. The locals had withdrawn, given them space, but Ark could see faces in the shadows at the far end. People who had used this corruption technique for generations, who thought they'd invented it, who were learning in real time that something older had shaped their knowledge.
He kept it short. Lira presented the frequency data. Dex asked three clarifying questions. Mira said nothing.
Kroft leaned against the far wall with her arms crossed. "So we have an Architect who taught Void management to an isolated settlement. We have Prometheus with Architect-derived relay node modifications. Same source, different recipients."
"Different timelines too," Ark said. "The settlement's been using this technique for centuries according to their records. Prometheus's modifications are recent. Could be the same Architect, could be different ones."
"Or the same one at different points in its lifespan," Veyla said. The Tessara advisor had been quiet since they'd arrived in the settlement. "Architects didn't experience time the way biological species do. A century of human time might be a single operational period for one."
"Great," Dex said. "An immortal alien architect has been running a quiet long-game influence operation across the interstitial spaces for at least two hundred years." He looked at Ark. "Does that change our immediate operational picture?"
Ark thought about it.
"It means Prometheus isn't improvising," he said. "Whatever they're doing with the relay nodes, they had guidance. The person inside Prometheus who reached the Architects — they weren't lucky. They were selected, or they sought it out deliberately."
"Which tells us something about the bridge program," Kroft said.
"Yeah." Ark looked at Jace, who was sitting against the wall with his arms wrapped around his knees, unusually still. "It tells us there are humans who've been thinking about Architect contact for a long time. Before the Awakening. Before the System. Before any of us knew what we were living inside."
The room went quiet.
In the corner, Jace's shadow-edged Blade Dancer class flickered once, briefly, and went still.
Nobody mentioned it.
But everyone noticed.
