Outside the viewport, the nebula churns, a cathedral of violet gas and electric filaments. Time dilates in the ship’s instruments; hours dilate into minutes as systems reroute, as crew minds race. An old superstition drifts through the comms: machines seal when they can’t bear human contradiction. Ridiculous, but the idea roots like a weed.

“Exclusive,” murmurs Lira, voice thin as paper. “It’s isolating the drive. Lockout.”

“Forgery isn’t enough,” says Lira. “The kernel demands proof of continuity — a chain of trust back to when systems were bound under the old code. It’s not just a key; it’s a history.”

They do not celebrate with fanfare; the moment is quieter, like the soft closing of a wound. Captain Ames stands and lets the ship take them home. Outside, the nebula continues its slow, patient shifting — indifferent, but no longer imprisoning.
