Caspian is already there. He's bleeding from a cut above his eyebrow and his jacket is torn at the shoulder and his green eyes are fixed on a man standing fifteen feet from the Headmaster. Not a student. Not a staff member. Older, gray at his temples, with Caspian's jaw and Caspian's cheekbones and none of Caspian's restraint.
"Your uncle," Ryder says, appearing at my left. He has a cut on his forearm that he's ignoring completely. "He was inside the whole time. He set the anchor."
"Caspian knows?"
"He figured it out thirty seconds ago." Ryder's eyes track the wraiths moving through the hall. "He found the anchor, which was embedded in the east tower's foundation stone. Took it down. But before it collapsed, the uncle activated a secondary sequence."
"What secondary sequence?"
"Ask Caspian," Ryder says. "He's the one currently deciding whether to kill his blood relative."
Across the hall, Caspian's uncle spreads his hands and says something to Caspian I can't hear over the sound of another crack in the stone ceiling, and Caspian's face does somethingterrible. Not rage. Worse than rage. The face of someone who had suspected a thing for a long time and is now being handed the confirmation like a gift wrapped in poison.
"Caspian," I call.
He doesn't turn. His uncle smiles, says something else, and the wraiths nearest to them shift their orientation as if receiving a command, and I understand then that the uncle is the reason there are dozens of them. He's been channeling them. Feeding them through. Directing the attacks from the beginning, not the Headmaster, not alone, using the Headmaster as cover while he worked the real mechanism from inside the walls.
Caspian moves before I can say anything else. He crosses the distance between them in four steps and drives his hand through the ward his uncle throws up like it's paper. His uncle stumbles. Caspian catches him by the collar and the two of them exchange words at close range that I cannot hear and don't need to, and then something dark and absolute moves across Caspian's face and he does what needs doing.
It's fast. His uncle doesn't make a sound. He just stops, and goes still, and Caspian holds him upright for one breath before lowering him to the floor, and the wraiths in the hall shudder all at once as if the thread controlling them has been cut. Some of them dissolve immediately. The rest scatter, losing cohesion, drifting apart at the seams.
The hall goes quieter.
Caspian straightens. He's still facing away from me and his shoulders are absolutely rigid and there's something dark spreading up the back of his right hand that wasn't there when he came into the hall. A stain under the skin, moving like ink dropped in water, tracing the lines of tendons and veins.
"Caspian." I reach him in seconds. "Your hand."
He turns. His green eyes are wrong, the pupils too large, expanding and contracting irregularly. "The anchor waswarded," he says. His voice is level, which is how I know it's bad. "He placed a curse on the anchor that transfers on destruction. Ryder and I destroyed it. I took the larger portion."
"What does it do?"
"Partial wraith transformation." He looks at the stain on his hand with something I can only describe as detached assessment. "I have a window before it progresses. Maybe an hour."
"An hour to what?" Ryder asks, coming up on my other side.
"To reverse it. Or to not reverse it." Caspian flexes his fingers and the movement is slightly wrong, slightly too slow. "There's a reversal component in the Veil itself. A counter-ward that requires a Conduit to anchor it. The prophecy structure built in a failsafe." His eyes move to me. "Which is why the Architect designed the trap the way they did."
"The Architect," Ryder says. "Not the Headmaster."
"The Headmaster was a tool. My uncle was a tool. They were both working for someone who has been moving pieces since before any of us arrived at Nocturne." Caspian's jaw tightens. "The bonds. All three bonds required under crisis conditions. The Architect needed the bonds formed within a specific window, because during the sixty seconds of bond integration, the Conduit's absorption field opens completely. No filter, no resistance. Just an open channel that anyone with the right knowledge can step through."
The silence in the hall is heavy. Around us, students are pulling themselves upright, tending to each other, and I register all of it distantly because what Caspian just said is still rearranging itself into a shape I can hold.
"The bonds were never about saving the Veil," I say.
"The bonds were about creating a door," Caspian confirms. "A sixty-second window where the Architect can use the openchannel to transfer into a body that can contain them. The Conduit's body." His eyes are steady on mine. "Yours."
"Which bonds have formed?" Ryder asks.
I already know the answer before Caspian says it. Mine with Ryder. Partial bond with Thane, not complete, the morning in the cold with his hand over mine, the understanding without the full seal. Two out of three.
"The Ryder bond is full," Caspian says. "The Thane bond is partial. That partial status is causing a cascade problem." He looks at Ryder. "An incomplete bond in the triad creates instability in the bonds that are complete. The partial Thane bond is putting structural strain on yours."
Ryder's face doesn't change. But he puts one hand flat against the stone of a nearby pillar, and I see his knuckles go white, and I understand that the strain Caspian is describing isn't abstract.
"How bad?" I ask Caspian directly.
"Lethal, given enough time. The incomplete bond acts like a fracture in a load-bearing wall. It spreads." Caspian holds my gaze. "Ryder has hours, not days."
