The Overseer of Prison Worlds was in charge of the Galactic Republic's prison worlds, and the Confiscation Authority. When Jedi Knights Obi-Wan Kenobi and Siri Tachi, as well as their Padawans Anakin Skywalker and Ferus Olin, took on the identities of arrested members of the Slam gang as part of a plan to arrest Jenna Zan Arbor, they needed to requisition the criminals' ship. They enlisted the aid of Tyro Caladian, a senatorial aide, who in turn had to get a waiver from the Senate Security Committee to meet with the Overseer of Prison Worlds. The Overseer of Prison Worlds then issued an order to the Confiscation Authority to allow the Jedi to commandeer the Slams' ship, a Ubrikkian star yacht.
