Black Iron Prison

The Black Iron Prison is a penitentiary on Callisto owned and operated by the United Jupiter Company. A dark and unpleasant place, the prison itself is a cold, souless place of metal and concrete, where prisoners live in cramped cells, with two bunks, a pair of chairs, a seat, and the everpresent holographic overseer watching the prisoners every time of the day and night. Corporate robots patroll the dark corridors for any signs of escapees - not that they have a lot of places to escape to, of course.

Facilities

 * The prison consists of numerous areas, judging by the trailer, including:
 * The cell blocks, with rows upon rows of orderly, and heavily unpleasant cells.
 * Medical bay, for treating ailments. Likely prisoners too.
 * Docking tower, where craft such as Charon transport shuttle dock to unload supplies and transfer prisoners and staff.
 * Administration, occupied by the Warden and with surveillance connected to every spot on the penal colony.
 * Biomes, large geodesic domes.
 * Open air mines, where massive draglines remove massive amounts of Callisto's dead surface.
