Thousands of years before the Republic conceived of the notion, a species known as the Rakata turned Belsavis into a prison planet. From what little scientists have learned by studying ancient writings and from the decaying memory banks of Rakata warden droids, Belsavis was built to hold monsters, warlords and so-called “lords of the infinite”‒anything the primeval and incredibly powerful Rakata feared.
The Belsavis prison administration calls the Rakata section of Belsavis “the Tomb.” Here, prisoners are held in eternal stasis, frozen in place and denied movement and thought by ancient technologies. Not all the inmates are ancient, however‒many were given by the Republic to the warden droids for safekeeping, when no other cell could hold them.
Through the use of droids, remote-controlled probes and rare exploratory teams, the Republic has set up a series of monitoring and communication stations throughout the Tomb. Despite this, only a tiny portion of the Tomb has been explored; this is the domain of the ancients.
