As a planet controlled by the Techno Union, Mustafar was a member of the Confederacy of Independent Systems, but remained largely untouched by the Clone Wars. As the war progressed, Count Dooku and the Separatist Council saw fit to build a fortified stronghold on Mustafar to be used in the event that the war against the Galactic Republic did not go well. The Techno Union, the Commerce Guild and the Trade Federation funded the costly fortress, which was designed to be able to withstand any prolonged assault. Mustafar's terrain and environment made it difficult enough to reach the bunker, but it was designed so that even if enemies could pass the terrain, they would be unable to take the fortress. Tractor beam and ray shield technology protected the fortress from the lava rivers and the interior chambers were climate-controlled.This is where Anikan Skywalker and Obi-Wan Kenobi fight.
