The Cells of the Lords of the Infinite was the name given to a volcanic cavern that was one of the sections of the Tomb, an ancient prison built on the planet Belsavis by the Rakata. A lava pool was located in the center of the cave, and the upper part of Megasecurity Ward 23 sat on an outcropping in the middle of the lake. A number of vaults were located in the cavern and held powerful prisoners, such as Sith and Subject 13.
