Megalox

Megalox, also known as Megalox Beta Penitentiary or Megalox Penitentiary, was a privately run prison located on the planet Megalox Beta. The planet's immense size and density made the natural gravity of Megalox Beta ten times stronger than standard gravity, which would crush any organism that dared venture planetside. A grav-field projected by a space station in the planet's orbit encased the prison below, protecting the prisoners from Megalox Beta's intense gravitational force—but also ensuring that they could not escape. Megalox was overseen from the station above it by Warden Luta and several guards; however, the guards were not posted in the actual prison. Rather, the prisoners were left to govern themselves, surviving on supplies sent down from the station by Luta.
