Darth Vader pledged his loyalty to Darth Sidious as the Clone Wars came to an end. Kneeling before his dark master, Vader assumed the mantle of Dark Lord of the Sith. His first assignment was to wipe out the Jedi Temple. After Vader was defeated by Obi-Wan Kenobi and suffered severe injuries, his power was diminished. Darth Sidious rebuilt his apprentice, but kept his sickly yellow eye open for another who could take his place.
