Mustafar is a small planet in the Outer Ring near the Ninth Quadrant.
Mustafar is a volcanic planet where valuable lava resources are extracted. It is also the last capital of the Confederation of Independent Systems and the place where it came to an end when Darth Vader assassinated the leaders of the Separatist Council. Mustafar is also the scene of a fierce duel between Darth Vader and Obi-Wan Kenobi, as a result of which Vader was forced to wear an armored mechanical suit for the rest of his life.
Mustafar is a young planet torn apart by the opposing gravitational forces of the giant gas giants. Locals travel by riding thick-skinned lavlhi to extract natural resources. The Mustafars run smelting facilities built by the separatists.
