Duel on Mustafar

After the end of the Clone Wars and the execution of Order 66, Obi-Wan Kenobi and Darth Vader engaged in a lightsaber duel on the lava planet Mustafar. It began after Emperor Palpatine tasked Vader, his new apprentice, with assassinating the leaders of the Confederacy of Independent Systems on Mustafar. Vader was followed to Mustafar by his wife, Padmé Amidala, who he wounded after seeing Jedi Master Obi-Wan Kenobi; Vader wrongly believed that Amidala had led Kenobi, his former master, to Mustafar in order to kill him.

The duel took place across a Separatist installation on Mustafar, with the two combatants making their way through hallways, conference rooms, and command centers, the latter of which led to them inadvertently triggering a meltdown on the facility. As a result, the facility's shielding began to collapse under the heat and lava on the planet. The fight moved onto a lava river, before ending on an embankment where Vader's left arm and both legs were severed. Following an impassioned indictment by Kenobi of how Vader, believed to have been the Chosen One, was meant to destroy the Sith instead of joining them, Vader's body burst into flames from the lava and he was burned alive. Kenobi retrieved Vader's lightsaber and left him on the embankment to die, before fleeing the planet with the dying Amidala.

Palpatine sensed his apprentice's struggle from across the galaxy and personally went to Mustafar to retrieve him. The Emperor brought Vader back to Coruscant, where he placed his badly-wounded apprentice into a cybernetic suit of armor that would keep him alive for the rest of his life. Kenobi, meanwhile, brought Amidala to Polis Massa, where she died shortly after giving birth to her and Vader's twins, Luke and Leia Organa. Kenobi took Luke to Tatooine and went into exile, and would not meet Vader again for several years. Their final encounter took place on the Death Star, where Vader killed his former master. Years later, Vader was eventually redeemed by his son and joined Kenobi in the Force.
