The facility never fully slept.
There were always lights somewhere. Always footsteps in distant corridors. Always the low hum of rune infrastructure running its endless cycle of monitoring and containment and control.
Isaac had learned its rhythms years ago.
He knew which corridors cycled their patrols at twenty minute intervals. Which camera angles had blind spots worn into them by years of the same fixed rotation. Which doors used rune locks that stuttered slightly in the presence of his curse — not enough to trigger an alert, just enough to give him a half second window.
He moved through the facility the way he always moved through it at odd hours.
Like he owned it.
Like he was the thing the facility should be afraid of, not the other way around.
He stopped outside the records annex on sublevel four. Not Sublevel 9 — that was too watched, too layered with monitoring he couldn't slip past without leaving a trace. But four was administrative. Quieter. The kind of floor where people processed paperwork and ran background checks and filed reports that nobody read until something went wrong.
The door stuttered.
Isaac stepped through.

The terminal took four minutes to navigate.
Bureau filing systems were designed to be comprehensive and deliberately difficult to search without clearance codes. Isaac didn't have clearance codes. He had something more useful — years of watching technicians run searches from the other side of the glass in Sublevel 9, memorising the architecture of the system the way other people memorised faces.
He typed Maren Soleis into the search field.
The file that came back was clean. Too clean. The kind of clean that meant someone had gone through it deliberately and removed everything that mattered, leaving just enough to satisfy a cursory check. Employment record. Research credentials. Bureau appointment date.
Six years ago.
Isaac stared at that date for a moment.
His contract with the Bureau was five years old.
She had been here a year before him. Before his capture. Before the white room and the metal doors and the children screaming.
He scrolled further.
Most of the early records were redacted — thick black lines where names and project titles should have been. Standard Bureau erasure. But one line had been missed. A single project reference in a footnote so small it had probably survived the redaction by accident.
Project Echo.
Isaac stopped scrolling.
He read it again.
Project Echo. Initiated seven years prior. Lead researcher: M. Soleis. Status: Active.
Seven years ago Echo would have been five or six years old.
Isaac sat with that for a long moment in the quiet of the administrative floor, the terminal light the only thing illuminating the room, the facility humming around him like it always did.
Then he closed the terminal, put everything back exactly as he found it, and walked back toward the third floor.

Cael Calder was not a complicated man.
He had loyalty and he had a job and in his experience those two things were only a problem when people confused which one came first.
The Bureau came first. It always had. Not because he was cruel or because he didn't like Lucien's squadron — he did, genuinely. They were good soldiers. Cael made them sushi on Fridays and remembered how everyone took their coffee and meant it when he laughed at their jokes.
But good soldiers and the right side of history were different things.
He found Lucien in the corridor outside the tactical room, reviewing something on his tablet, still carrying that particular tension he'd been wearing since the Hollowlands.
"Commander." Cael fell into step beside him, easy and unhurried. "You got a minute?"
Lucien looked at him. "What is it?"
Cael smiled. Not the wide easy one he wore for the squadron. Something quieter. More considered.
"I just want to say — what happened on the third floor last night. The incident with the girl." He paused. "The Bureau understands these things are complicated in the field. Nobody is questioning your judgment on the extraction."
Lucien said nothing. Waiting.
"But there are people above both of us who are paying very close attention right now," Cael continued. "To the girl. To Unit Seven. And to the people around them." He let that sit for exactly the right amount of time. "I'd hate for anyone's record to get complicated over a situation they didn't fully understand."
Lucien looked at him for a long moment.
Something had shifted in Cael's face. Just slightly. The friendliness was still there but it was sitting differently now — less natural, more arranged. Like a piece of furniture that had been moved an inch and the room hadn't quite settled around it yet.
"Are you warning me?" Lucien asked quietly.
Cael's smile returned to its usual position. "I'm looking out for you. That's all."
He clapped Lucien once on the shoulder and walked away down the corridor, easy and unhurried, already thinking about something else.
Lucien stood still and watched him go.
And understood, for the first time, exactly what Cael Calder was.

Isaac came back to the third floor at the hour before dawn.
The corridor was quiet. The rune lights were on their night cycle — dimmer, slower, the facility breathing differently at this hour.
He turned the corner toward Echo's room.
The door was open.
Not forced. Not damaged. Just open, the way a door is open when someone with the right codes and the right authority decides it should be.
Isaac stopped in the doorway.
The room was empty.
The bed was neatly made — not slept in, not disturbed. Like someone had come in and tidied it deliberately. Like they wanted it to look voluntary.
The Fragment burns were still on the floor from two nights ago. Dark and deliberate, spreading from where Isaac had stood, a map of something that had almost happened.
He stood in the doorway and looked at them for a long time.
The curse stirred.
Low and quiet at first. Then less quiet. Then not quiet at all.
Isaac didn't tell it to stop.
He just stood there in the empty doorway with the burn marks at his feet and something building in the dark behind his blindfold that had no name yet but would have one soon enough.
Somewhere in the facility Maren Soleis was writing in her notebook.
Project Echo. Phase Two.
The cursor blinked on an empty page.
Isaac turned away from the empty room and walked back down the corridor.
His shadow didn't follow him the way shadows usually do.
It went ahead.
