The Trogan system, a star system situated in the Jospro sector of the Outer Rim Territories, encompassed the planet known as Trogan.
Following Talon Karrde's incarceration, this star system served as the refuge for Aves and the rest of Talon Karrde's group. Mara Jade journeyed to this place to guide the smugglers to the Katana fleet, preceding the arrival of Borsk Fey'lya's team.
