Rakatan Prison

This was a pyramid shaped device used by the Rakatan's Infinite Empire to imprison dissidants. Darth Revan, who was at the time suffering amnesia, brought on by the Jedi Council found one of these and was challenged by it's prisoner. The device was to be delivered as a favor from a local Hutt in Anchorhead on Tatooine in ~4,000 BBY. It is assumed that others had been trapped in the prison as well.
