Obi-Wan Kenobi was an Jedi Master during the Clone Wars and later would go into exile on the planet Tatooine after the rise of the Galactic Empire. After years of exile on the planet, Kenobi would briefly aid the Rebel Alliance when a pair of rebel droids, R2-D2 and C-3PO arrived on Tatooine, carrying the Death Star plans, and with a message that asked if Kenobi would join the rebellion. Kenobi would attempt to get the droids back into rebel hands with the aid of Luke Skywalker, Han Solo, and Chewbacca but would fail as Alderaan would be destroyed by the Empire. Following this discovery, Kenobi and his allies were captured aboard the Death Star, during this time, Kenobi would encounter his fallen apprentice, Darth Vader, who would kill Kenobi in a lightsaber duel. Kenobi's ghost, however, would live on, aiding in the training of Luke Skywalker, up until the Battle of Endor, in which Luke became a Jedi Knight after redeeming Vader and killing the Emperor.
