The Praxlis sector was a sector located within the Core Worlds of the galaxy. It contained the Praxlis system.
During the Imperial Period, the Praxlis sector was located at the center of the Galactic Empire's rim territories and was defended by the Black Sword Command.
Praxlis was referred in only one line in Before the Storm: "Black Sword Command defended the center of the Empire's Rim territories. Praxlis, Corridan, the entire Kokash and Farlax sectors." and let the nature of Praxlis and Corridan ambiguous. Praxlis and Corridan were interpreted as planets in the Star Wars Encyclopedia and The Complete Star Wars Encyclopedia but they were eventually stated as sectors in The Essential Atlas Online Companion.
