this gang of criminals was founded by Roper Slam and Valadon on their homeworld of Mamendin, during the years following the Battle of Naboo. After successfully carrying out minor crimes on Mamendin, the Slams branched out and started doing jobs on other worlds in the Core, including the theft of the entire planetary treasury of Vuma. However, after trying to break into the secure vaults of the Commerce Guild, they were caught and sent to the Greylands Security Complex on Tentator. About two years before the Clone Wars broke out, the four-being gang managed to escape from Greylands. However, their starship remained impounded, and was later used by Obi-Wan Kenobi and Siri Tachi. The two Jedi Masters, along with their apprentices Anakin Skywalker and Ferus Olin, used the ship to impersonate the Slams, during a mission to capture Janna Zan Arbor on Romin.
