Duel on Mustafar/Legends

The Duel on Mustafar was the event in the Great Jedi Purge in which Darth Vader was injured by Obi-Wan Kenobi and had to undergo reconstruction and surgery.

Prelude
The duel occured in the aftermath of the Mission to Mustafar, in which Darth Vader slaughtered the Separatist Council and ended the Clone Wars. He met up with his wife, Padme Amidala, during the aftermath of the massacre. Obi-Wan Kenobi, hiding in the cargohold of her Naboo Skiff, appeared to Vader, making it seem like it was a trap laid out by Padme. In his rage, Vader strangled his wife to near death, knocking her unconscious. The former best friends were forced to confront each other in battle.

The duel
The two battled each other on the landing platform and made their way through the hallways of the mining facility. In the conference room, Vader forced Kenobi's lightsaber handle into his throat, temporarily paralyzing him, and attempted to decapitate his former master. Kenobi managed to fling himself out of his former padawan's grasp, and the two proceeded into the control room. The two forced each other into opposite ends of the room with a combined force of force push. Attempting to kill Kenobi, Vader jumped at Kenobi and missed, and accidentally destroyed the lava bridge control panel, weakening the bridge system outside the complex.

As the two battled on the lava bridge outside, lava weakened the already weak bridge, bringing it down. The lava river dragged the bridge down a lavafall, and nearly killed Vader. The two managed to get off the bridge and land on a lava platform and lava mining droid.

Fall of Vader
"It's over, Anakin! I have the high ground!"

- Obi-Wan

"You underestimate my power."

- Anakin

"Don't try it!"

- Obi-Wan

As the two dueled their way to the shore, where Obi-Wan jumped and gained the high ground. Vader foolishly risked his life and jumped at Obi-Wan, getting his three remaining organic limbs severed. He tumbled down to the shoreline, ignited on fire, and had his flesh burned off. Kenobi left him to die in agony.

Aftermath
Palpatine and a squad of Shock troopers picked up Vader's remains and went to Coruscant for him to undergo surgery and reconstruction. Kenobi, Bail Organa, and Yoda set off to Polis Massa to bring Padme for medical care, where she gave birth to Luke and Leia. Vader would now live the rest of his life in a life support suit, Padme perished, and Kenobi would hide on Tatooine, waiting for the day Luke would be trained as a Jedi.
