They left the settlement at dawn on Day 141, Lira walking with them back to Zone 7's edge. She didn't speak much. Ark noticed she kept looking at Jace, then looking away, the same expression the settlement people had worn when he'd told them about the Architect frequency in their containment design.
Like the ground had moved and they were still waiting to find out what direction.
At the corridor threshold, she stopped.
"I'll need to report to the council," she said. "About the expedition. About what we found."
"What will you tell them?" Kroft asked.
Lira considered it. "The truth. But not all of it at once." She looked at Ark. "The seal order came from fear. If they understood that there's an Architect actively working in the interstitial spaces, that the corridor is connected to something much older than the current political situation, the fear gets worse, not better."
"So you'll manage it," Dex said. Not accusatory. Just stating it.
"I'll sequence it." She held out her hand to Ark. "Come back through. If you can. After."
He shook it. Her grip was firm.
They walked into the corridor. Behind them, the pocket settlement's entrance closed, the dimensional fold sealing back into nothing, and the passage looked like any other stretch of featureless corridor wall.

Back at the Zone 7 staging position, Ark pulled up his system metrics.
*System stability: 71%*
*Classes active: 97 of 127*
*Dimensional frequency integration: 40% of authentication threshold*
Forty percent. Pel's models said he needed a hundred to strip the node modifications. That gap wasn't going to close by waiting.
"Okay," Ark said. "Let's talk about the acceleration timeline."
Pel was already on it. He had three different projection models pulled up on his field display, each representing a different session intensity. Sera stood next to him with her arms crossed, reading over his shoulder.
"Controlled exposure in the gap section," Pel said. "The deep-zone Void substrate acts as a frequency amplifier. Your body is already producing dimensional output, and sustained exposure accelerates the integration. Think of it like a catalyst."
"What's the cost?" Dex asked.
"System instability during the session. The classes compete for operational priority when the dimensional frequency spikes, and the Warden has to arbitrate. It drops, then recovers. Net gain each session." Pel tapped the first projection. "Conservative approach: six sessions over four days. Reaches full threshold with minimal instability spikes."
"We might not have four days," Dex said.
"Aggressive approach: three sessions over two days. Higher instability risk. Some chance of cascade." Pel tapped the second projection. "I'd say fifteen percent per session."
"No," Sera said.
"Measured approach," Pel continued. "Four sessions, Day 141 and 142. Higher exposure duration per session than conservative but shorter than aggressive. Better recovery windows." He looked at Ark. "This is the one I'd recommend."
Ark looked at Sera.
"I want monitoring threads the entire session," she said. "If I say stop, you stop."
"Agreed."
"And not just for the cascade risk. Your class architecture is reorganizing. I need to document the changes as they happen, not after."
"Still agreed."
She held his gaze for a moment. Then: "Okay."

The first session was in the afternoon.
The gap section sat between Zones 6 and 7, a stretch of corridor where the Void substrate pressed closer to the walls than normal, where the air felt thicker, where Ark's guardian frequency always ran a few points higher. He'd avoided spending time here except to check the relay nodes. Now he was sitting cross-legged in the center of it with Sera's monitoring threads sunk into his shoulders and Dex standing at the far entrance watching the corridor.
"How does it feel?" Sera asked.
"Like the frequency is getting louder." He tried to find better words. "Like turning up the volume on a channel that's already running in the background."
"Your stability is at 71. Holding."
He let the gap section's ambient field do its work. He didn't push. Pel had been clear that the acceleration was passive, the body doing the integration on its own given sufficient stimulus. The session was about exposure, not effort.
Fifteen minutes in, his stability dropped.
"69," Sera said. "Still controlled."
It felt like standing in a current. Not painful, just uncomfortable. His classes were restless. The Warden was working, pushing processing priority down through the list, managing competing signals from 97 different class architectures all responding to a frequency input they hadn't been built for.
Somewhere in the system, things were shifting.
Twenty-five minutes in, his stability hit 67.
"Ark."
"Still here."
"Dimensional frequency is at 44."
That was four points in twenty-five minutes. Better than Pel's conservative projection.
He held another five minutes, then Sera pulled her threads and called it.
They walked back to Zone 7. He felt the stability number recover as they moved away from the deep substrate. 68, 69, 70. By the time they reached the staging area it had climbed back to 72. Net gain of one.
"The frequency component," he said.
Sera was already reviewing her readings. "47% of threshold."
Seven points. First session.
"Write it down," he said.
"I'm writing everything down." She didn't look up from her notes. "Your class reorganization is visible. The structures adjacent to the dimensional output channels are shifting. The Warden is adapting, building new priority trees around the frequency." A pause. "It's doing what mine does when I'm threading through unfamiliar tissue. Learning."
He thought about the Necromancer class. The Berserker class. Classes built for specific purposes, now sitting in an architecture that was becoming something different.
"They'll change," he said.
"Some of them." She finally looked up. "Yes."

The session put him at 47%. Dex found him an hour later, before the second session.
"The Director wants to talk."
Kroft had set up a small operations corner in Zone 7: a crate, two field lights, a secure communication terminal that she'd confirmed wasn't broadcasting. Ark sat across from her.
"Independent investigation," he said. "You were running one."
"Since three months after the first relay node appeared," she said. "Before I approached your team. I wanted leverage before I asked for help." She didn't look apologetic about it. "I've been backtracking the technical knowledge that Prometheus's relay modifications require. Not just the Architect-derived engineering, but the human interface. The translation layer between dimensional mechanics and the class system."
"That's specialized."
"That's the point. There are maybe forty researchers in the System zones who understand class architecture at that level. I've been eliminating them one by one." She folded her hands on the crate. "I have a name."
Ark waited.
"Dr. Elena Voss. Molecular biologist, not a class theorist — but her pre-Awakening work was on cellular frequency resonance. Pattern integration in complex biological systems. After the Awakening, she shifted focus. Spent three years publishing on class architecture as a biological phenomenon." Kroft paused. "Then she disappeared. Two years before the Awakening, she'd made contact with something in Zone 9. Something she documented in encrypted files my team spent four months breaking."
"And the files said?"
"Non-human communication. Structured signal patterns. She was trying to decode them." Kroft looked at him. "She may have been Prometheus's first contact with Architect intelligence. And she's either still alive and inside the program, or she was the reason the program exists."
Something about the name sat wrong. Not familiar. Wrong. Like a piece fitting a space and him realizing the space was always shaped for it.
Voss.
He pulled up his team's personnel files in his system overlay. Standard practice, he maintained basic records on everyone operating with him in the corridor.
*Sera Voss. Life Weaver. Field medic.*
He looked at Kroft.
She was watching him with the steady expression of someone who'd already connected the thread and was waiting to see how long it took him.
"Voss," he said.
"Yes."
"Elena Voss."
"Yes."
He sat with it for three seconds.
"Does Sera know you know?"
"No." Kroft leaned back slightly. "I found the connection yesterday. I brought it to you first."
He stood up. Outside, across the Zone 7 staging area, Sera was writing in her field notes, hunched over the same data she'd been collecting on his class integration, cross-referencing with the settlement's Architect frequency readings. Her handwriting was fast and small. She'd been at it for two hours.
"I'll tell her," Ark said.
"I need you to understand the security implications—"
"I'll tell her," he said again. "Tonight. Before the second session."
Kroft held his gaze. Then she nodded once.
He walked back across the staging area toward Sera, and the corridor hummed around him at its constant frequency, patient and old and full of things nobody had finished learning yet.
