Before the world ended, Zera was already locked away.

Patient Z999.
Cell 50.
No surname. No family. No remorse.

For ten years, the underground hospital kept him buried beneath rules, cameras, and reinforced doors. Then World War III begins. The pandemic spreads. Nuclear fire stains America. The locks fail.

But Zera does not run.

He waits.

Because to a madman who never feared the cage, the apocalypse is not freedom.

It is an invitation.
