In "Star Wars: Episode III – Revenge of the Sith," Anakin and Obi-Wan battle on Mustafar. Mustafar is a volcanic planet in the Star Wars galaxy, covered by lava flows, ash, and jagged industrial landscapes.
After becoming Darth Vader, Anakin travels to Mustafar to eliminate the Separatist leaders hiding there. Obi-Wan follows him, leading to the film’s climactic lightsaber duel. The fight ends when Obi-Wan gains the higher ground and severely wounds Anakin, who is later rescued and transformed into the armored Darth Vader.
Mustafar is often confused with other important Star Wars locations, such as Coruscant, where Anakin turns against the Jedi, and Naboo, where he later meets Padmé. The planet’s significance extends beyond Episode III: it also appears in later Star Wars stories as a symbol of Vader’s fall and suffering.
