Planetary Penal Exclusion Zone

Death Zone

A vast and inhospitable expanse carved into Gallifrey’s surface, the Death Zone is a land where nature’s cruelty meets the Time Lord’s arrogance. Jagged metallic corridors twist through uneven terrain, their walls etched with the scars of countless failed experiments, the air thick with the hum of latent temporal energy. Dust clings to every surface, disturbed only by the erratic movement of those trapped within—a skeletal figure left abandoned to the Zone’s merciless watch. The ground slopes imperceptibly toward a looming presence on the horizon: an obsidian structure crowned with jagged spires, its shadow casting no light across the ground. In the distance, energy fields flicker like unsteady curtains, marking the boundaries of a prison designed to hold beings stolen from time itself. The Zone breathes with unseen peril, its very name a warning etched into Gallifrey’s history.
