Perdition

Perdition is a prison-planet in Alpha Sector, and a founding member of the Galactic Correctional Agency. It is the largest prison world in existence, and holds inmates from nearly every planet in the galaxy. Perdition is known for its harsh environments, and mostly free roam areas. The planet is often perceived as having lax security, however Perdition is very secure. Prisoners are outfitted with shock collars which can be activated at any sign of trouble. While Prison guards are limited to the sensitive areas, such as shuttle docks, and food supply areas, they have kill only weapons. If any inmate causes trouble, the guards will kill him without a second thought. The shuttle bays are also highly protected, which is necessary in order to keep the inmates on-world.

Perdition and Tartarus
Perdition's second moon, Tartarus, serves as another prison-world. Regardless of their close proximity and relationship, the two worlds are very different. While Perdition is, for the most part, a standard prison-world, Tartarus utilizes a computer network program, and brain implants that trap the inmates psyche into a virtual world. Often times prisoners will be transferred between the two worlds, depending on their offenses, or risks.
