Adran jerks back. Sera uses the half breath to snatch the map tube from his hand and throw it across the seam. At me.
I catch it against my chest. The map sparks blue-white through the stone tube. Pain slams through my burned hand. I hold.
Sera grins at Adran. It is not a nice expression.
“That was me helping,” she says.
The floor under her cracks. The grin vanishes.
I move before thought, but the seam between us flares higher, a wall of white-gray light. Not solid. Worse. Active. It hums with the same cold bite as the anchor.
“Kavor, don’t touch it,” Sera says.
“I know.”
My voice does not sound like mine. Adran backs toward the healthy sample pouch.
Rosalind’s voice snaps from the door. “Adran.”
He ignores her. His eyes are on the proof pieces, then Sera, then the map tube in my hands. Calculating paths. Combining pieces. He is not frightened enough. That makes him more dangerous. Sera sees it too.
“Everyone stop moving,” she says.
The command is not loud. It is precise. Virn freezes. Syin freezes. Rosalind stills. Even Adran pauses. Sera looks down at the floor. I do too.
The white-gray lines are not random. They connect the table, the seam, the proof, Sera, and me. A shape forms under us. Not open yet. Waiting for pressure. Waiting for the right movement.
The system does not only want the proof. It wants arrangement. Pattern.
“Adran,” Sera says slowly, “step away from the samples.”
He glances at the floor and sees enough to understand. Then he makes the choice that reveals him completely. He reaches for the healthy sample.
The chamber erupts.
Blue light bursts from the pouch. White-gray light spears up from the floor. The blackened sample slams inside its box like something alive. The broken anchor sparks and skitters across the table toward Sera.
She grabs the hide-wrapped anchor before it can touch her. The blue under her bandage flares. My burned hand answers. The map tube in my grip goes hot.
A line of light snaps from Sera to me across the seam. The unfinished bond, visible. The room sees it.
Adran sees it. The system sees it.
Sera’s eyes meet mine through the light. There is fear there. Yes. Pain. Yes. But not doubt.
“Kavor,” she says.
“I am here.”
“The proof isn’t the key.”
The line between us brightens. The floor beneath the west chamber unlocks, one ring at a time. I understand. So does she.
The map does not open the system. The sample does not. The anchor does not. They are teeth around a lock. We are what it wants to turn.
“No,” I say.
The word is not for Sera. Not for Adran. For the thing beneath us.
