The Spumani sector, alternatively referred to as the Grumani sector, existed as a sector situated within the Outer Rim Territories.
The Galactic Republic once included the Grumani sector. Nevertheless, during the time known as the Republic Dark Age, significant portions of the sector came to be dominated by the Sith. In the era of the Clone Wars, the Confederacy of Independent Systems maintained a substantial presence within the Grumani sector. Following the Battle of Virujansi, Obi-Wan Kenobi and Anakin Skywalker launched an assault on this sector.
