The stone wall Cero forced shut trembles under the ruin’s pulse. Blue light leaks from the seams in his shoulder and chest, and the chamber answers with a hungry hum.

Sable
Cero, look at me. Keep your mind on my voice.
Sable stands at the edge of the crystal glow, arms half-raised, shaken but steady. Her gaze never leaves him, even as the air around him warps.

Cero
The pulse is tied to my breath. If it keeps pace, it keeps control.
Cero drags in a ragged breath. The wind stirs, not outward, but inward, curling around the light inside him like a snare.

Sable
You can push it out. Or you can let it take the rest.
The chamber brightens once, hard and sharp, as if the ruin itself is waiting to see which way he breaks. Sable braces for the answer, and the blue fire in Cero’s veins surges toward the surface.
