Planet of Mustafar
"Birth of Darth Vader"
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.
The tiny world of Mustafar was a fiery volcanic world where lava was mined like a precious natural resource. It was also the last capital of the Confederacy of Independent Systems and the site of the Separatists' downfall, an event that shaped galactic history. It was also the site of a climactic duel in which Darth Vader dueled his former master, Obi-Wan Kenobi, and 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.
