The Tarabba sector designated a specific sector within the expansive Outer Rim Territories region of the galaxy. Within its boundaries lay the Utapau system, home to the planet named Utapau. Utapau served as the homeworld for both the Pau'an and Utai species. The Clone Wars saw Utapau become significant, initially as the location for a Jedi mission, and subsequently as the stage for a substantial battle fought between the forces of the Galactic Republic and the Separatist alliance.
