The Abrion sector was a sector of the Outer Rim Territories region of the galaxy, located at the confluence of several hyperspace routes. It contained the Rishi system, where a battle took place during the Clone Wars on the moon of the planet Rishi, as well as the planet Scarif, which was the site of a battle between the Alliance to Restore the Republic and the Galactic Empire. The sector was also home to several agriworlds, including Abrion Major, Gibad, Tieos, and Ukio.
During the Clone Wars, Abrion Major was represented by Esu Rotsino in the Galactic Senate, who led the sector in defecting from the Galactic Republic. In the Separatist Senate, Rotsino represented the entire sector.
