Mustafar, Outer Rim

Mustafar was a small volcanic planet located in the Mustafar system, situated between two gas giants in the Outer Rim Territories that was aligned with the Confederacy of Independent Systems during the Clone Wars and later taken over by the Galactic Empire after the Techno Union was nationalized at the conclusion of the conflict. During the Imperial Era, Mustafar became a fortified Imperial world as it housed Fortress Vader, the personal castle of Darth Vader.
