Daryan wasn't in the archive the next morning, or the one after. It was Elara who noticed first — not his absence exactly, but the shape of it, the particular quiet a person leaves when they've decided to disappear rather than simply not show up.
"He does this," Sion said, more to convince himself than her. "Goes quiet. Comes back."
"Not like this." Elara was already moving. "Not after what he said about Fayrius's methods. He wouldn't drop that thread and walk away from it."
They found him in the training yard, alone, running the same drill over and over — a defensive form, blade low, more discipline than aggression. Sweat had frozen along his collar despite the effort. He didn't stop when they approached.
"You've been avoiding the Hall," Sion said.
"I've been thinking." Daryan's blade cut the air in a clean, practiced arc. "Somewhere Fayrius isn't standing close enough to hear it."
"Thinking about what?"
Daryan finally stopped, breathing hard, and for the first time in the weeks Sion had known him, something in his composure cracked wide enough to see through.
"My father," he said. "You don't know this — I've never told anyone here — but my father was a Guardian. Second junction, forty years ago. He died believing he'd failed to protect something. I never knew what." He wiped the frost from his blade with more focus than the task required. "I keep thinking about your wall of handwriting. You already know who it is. And I keep wondering if the Path means someone in this Hall — or if it means I already know something about my own father that I've spent forty years choosing not to remember."
Elara said nothing. Sion had learned, by now, that her silences were their own kind of answer — she wasn't offering comfort because comfort wasn't what the moment needed.
"You think your father is connected to this," Sion said instead.
"I think everyone assumes the traitor is someone alive," Daryan said. "No one's asked what a Guardian's failure forty years ago might have left behind. Seeds don't ripen on anyone's schedule but their own."
It took the rest of the day to find the old junction record — buried, half-erased by frost damage, in the lowest archive shelf no one had touched in years. Daryan's father's name sat at the bottom of an incident report, the details scraped away by time or deliberate erasure, Sion couldn't tell which.
Guardian Vael. Second junction. Failed to close a breach in time. Cause: unrecorded.
"Unrecorded," Daryan read aloud, flat. "Forty years, and no one thought to write down why."
"Or someone made sure it wasn't written," Elara said.
Daryan's jaw tightened, and for a moment Sion saw exactly what Eldon had warned him about days ago — the particular shape anger took right before it stopped being useful and started being dangerous.
"If someone erased my father's failure on purpose," Daryan said quietly, "then whatever's happening now isn't new. It's just the same thing, finally circling back to finish what it started forty years ago."
Sion put a hand on his shoulder — brief, wordless, the kind of gesture that meant more from him than any speech could have. Daryan didn't shrug it off, which told Sion more than anything he'd said all day.
Behind them, unnoticed, the black frost had begun creeping across the old report itself, as if the Path had heard its own name spoken aloud and leaned in closer to listen.
