Rhys didn't say anything for a long moment, staring at the parchment in Seraphine's hands like it might rearrange itself into something easier to carry.
The chamber's faint, silver light seemed to press in closer around him, the weight of dozens of preserved memories on the shelves around them suddenly unbearable, as though the whole archive were holding its breath along with him. He thought of Ren's hands, steady around a needle and thread, steady even as he bled out in the dirt of their own yard. Steady enough, apparently, to have once helped decide that an entire bloodline should cease to exist.
"He killed for it," he said finally, quietly, more to himself than to her. "He killed for me, in that yard, three days ago, and he was one of the people who decided my whole bloodline should be erased in the first place."
"We don't know the full shape of it yet." Seraphine's voice was careful, gentle in a way that didn't try to smooth over what he'd just learned. "Keep reading with me before you decide what it means."
She turned back to the parchment, and Rhys forced himself to look again too, past the first gut-punch of Ren's name attached to something he'd never imagined, into the details underneath it.
"This isn't describing an erasure," Seraphine said slowly, tracing a line of cramped, hurried script. "Not originally. It's describing a containment agreement. Limits on how the Thirteenth Art could be used, restrictions passed down within the bloodline itself, meant to prevent exactly the kind of danger the old records call the Unraveling. Voss's name is here as one of the architects of that agreement, not the erasure that followed it."
"Then what changed?"
"I don't know yet. The record's damaged here, part of it lost when the vessel broke." She frowned, working through what remained.
"But whatever happened, it happened after the containment agreement was already in place. Something pushed the Houses from limiting the bloodline to erasing it entirely, years later. And if Elric Voss helped design the first agreement, and was exiled for refusing to help enforce the second—"
"Then he wasn't protecting a secret out of guilt for what he'd done." Rhys felt something shift in his chest, grief and anger tangling together in a way that refused to separate cleanly. "He was trying to undo it. Or stop it from getting worse."
"That's how I'm reading it too." Seraphine looked up at him, careful. "It doesn't erase what he did originally. He still helped build something that limited your entire bloodline before you were even born. But it isn't the same as a man who lied to you for seventeen years with no cause behind it either."
Rhys didn't have a clean answer for how he felt about that, and didn't try to force one. It sat in him instead, heavy and unresolved, grief and anger and something that might, given enough time, become a strange kind of forgiveness, none of it settled enough yet to name.
He thought about the mornings Ren had burned the porridge on purpose, the years of small, ordinary kindness stacked up against one enormous, unspoken debt neither of them had known was being paid down at all. It didn't cancel out. He understood that much clearly, even now. It simply sat alongside everything else, another weight added to a life that already carried more than its share.
"Isolde read this," he said instead, needing somewhere else to put his attention. "Before she vanished."
"She must have." Seraphine glanced back toward the disturbed shelving, the pile of examined vessels. "This was the last one she opened, based on where we found it. Whatever she learned here, it's likely connected to why she's gone now. Which means this wasn't random. Someone didn't just want the archive. They wanted to make sure nobody who read this particular record stayed available to talk about it."
"Someone who knew exactly what she'd find down here."
"Someone who's likely still watching this room, or has people who are." Seraphine's hand drifted, instinctively, toward her blade. "We should assume whoever took her knows we're here too, by now."
They were still turning the thought over when the soft, unmistakable sound of the archive's outer door easing open reached them from the top of the curved stair, careful and deliberate, someone taking pains not to announce themselves.
Seraphine went instantly still, one hand closing fully around her blade's hilt, the other rising in a sharp, silent gesture for Rhys to stay low and quiet.
They pressed back into the shadow of the disturbed shelving, Rhys's heart hammering loud enough in his own ears that he half expected it to give them away on its own.
Every second that passed without the footsteps pausing or hesitating told him the same thing Seraphine's tightening grip on her blade already had, whoever this was, they weren't searching. They were arriving somewhere they already knew.
Footsteps descended the stair, unhurried, familiar with the space in a way that told Rhys immediately this wasn't a startled guard stumbling onto them by accident. Whoever was coming down into the archive knew exactly where they were going, and clearly expected, or at least suspected, exactly what they'd find waiting at the bottom.
Rhys reached, carefully, for the sense he'd been learning to trust, feeling for the shape of whoever approached the way he'd learned to feel the truth beneath Bosk's nervous words, and felt something that made the hair on his arms rise all over again.
It wasn't the careful, businesslike wrongness he'd sensed from Bosk's lie, nor the cold, clinical stillness of the stranger who'd killed Ren. This was something else, harder, more disciplined, edged with a kind of contained, banked heat he hadn't encountered before, the texture of a temper trained rather than a temper spent.
Whoever was coming down those stairs didn't feel like a stranger at all.
They felt, unmistakably, like House Thane.
