Edge of Empire: From Crime to Consequence
Once a Hutt pleasure planet, Teth was largely abandoned as other, more enticing planets drew the attention of the fickle Hutts. For perhaps a thousand years, it was populated mostly by smugglers, and has only recently been populated by the Empire.
During the Clone Wars, Separatist agents captured the son of Jabba the Hutt and kept him imprisoned on this planet. The ensuring response by the Republic brought a great deal of troops to the planet, and the necessity of keeping a garrison within range of the Hutts became obvious thereafter. Emperor Palpatine, as part of his reorganization of the Outer Rim, established an Imperial base here, from where the Moffs of the Baxel system would oversee their domain.
