Mustafar

Mustafar was a small planet located in the Mustafar system of the Outer Rim Territories, coreward of Rutan, between the Hydian Way and the Ninth Quadrant.

A fiery volcanic world where lava was mined like a precious natural resource, Mustafar often served as a place to dispose of unwanted evidence, a quality which drew Black Sun to the planet.[7] It also drew the Sith: it was on Mustafar that Darth Maul began his Sith training. Mustafar also served as the last capital of the Confederacy of Independent Systems, and was the site of the Separatists' downfall, an event that shaped galactic history. In a duel that followed, Darth Vader fought his former master, Obi-Wan Kenobi, and lost, as a result of which he was forced to wear dark armor for the rest of his life.

Mustafar was a very young and volatile world, torn apart by opposing gravitational forces of the gas giants Jestefad and Lefrani, with the former being the closer of the two. Astride thick-skinned lava fleas, the natives leapt across the lava fields to mine the planet's deadly natural resources. Mustafarians oversaw the smelting facilities constructed by the Separatists on Mustafar.
