The Tantra sector, a sector situated in the Outer Rim Territories, neighbored the Elrood sector. The planet Tantra was part of it. Just prior to the onset of the Clone Wars, this sector, along with the Elrood, Danjar sector, and Sluis sector sectors, broke away from the Galactic Republic. This secession had the consequence of obstructing Republic vessels from using the Rimward section of the Rimma Trade Route.
