Cathar was the homeworld of Scape Loewig, a Force-sensitive child whose name was included in aurebesh in a memory crystal recovered by Jedi Chief Librarian Jocasta Nu following the destruction of the Jedi Order in 19 BBY. Shortly after joining the Galactic Empire's 204th Imperial Fighter Wing from the Imperial Academy, the TIE pilot Yrica Quell participated in a patrol on the outskirts of Cathar with her new squadron. Around 5 ABY, she was reminded of the patrol while flying through a debris field in the Cerberon system. Cathar shared its name with the Cathar species, which included Dhina, who served as an Ensign and comscan officer aboard the New Republic refitted Star Destroyer Deliverance in 5 ABY.
