Invasion of Belsavis

During the Great Galactic War between the Galactic Republic and the Sith Empire, the Sith launched the Imperial Prison Break Initiative on the Outer Rim world of Belsavis. The operation was the result of the Empire's discovery of a maximum-security Republic prison on the planet, known only as "the Tomb." The Tomb was the penal complex the Republic had been using to house captured Sith Lords and other dangerous criminals. Upon discovering its location, the Empire infiltrated the compound and attempted to liberate its captured subjects, but were challenged by other, non-Sith inmates also seeking freedom. The prison broke into chaos consequently, and Republic forces arrived to attempt to restore order. The battle on the prison grounds also affected a nearby prison created by the ancient Rakata Empire, which threatened to release a mysterious evil.
