An asteroid prison adrift somewhere in the black. Whatever it is on the paperwork, it is a black site.
Locations
The Rock8 inside
The upper wing, and where every prisoner's confiscated belongings are locked in the warden's vault.
The party's cell block. Four containment units, a common room, and a hand-carved star map scratched into the ceiling.
The prison library, and the only warm room on the level. Where the party found a guard being beaten to death.
Two dozen monitors, cold coffee, and a floor-to-ceiling gun safe standing open and empty.
Bulletproof glass over the main floor, holding the only working comm relay and the riot-glass trigger. The only way out is through it.
Where the lift lets out. Four signs, and the sound of fighting from all of them.
The main floor where the population mills about. Brighter and colder than anywhere else, by design.
The prison chapel, muffled in acoustic foam, where the Emperor's assassin died.
Nothing on record matches those filters.
