The droids are captured by Jawa traders, who sell them to moisture farmers Owen and Beru Lars and their nephew, Luke Skywalker. While cleaning R2-D2, Luke accidentally triggers part of Leia's message, in which she requests help from Obi-Wan Kenobi. The next morning, Luke finds R2-D2 searching for Obi-Wan, and meets Ben Kenobi, an old hermit who lives in the hills and reveals himself to be Obi-Wan. Obi-Wan tells Luke of his days as a Jedi Knight, former Galactic Republic peacekeepers with supernatural powers derived from an energy called The Force, who were all but wiped out by the Empire. Contrary to his uncle's statements, Luke learns that his father, Anakin, fought alongside Obi-Wan as a Jedi Knight. Obi-Wan tells Luke that Vader was his former pupil who turned to the dark side of the Force and killed Anakin. Obi-Wan presents Luke his father's weapon - a lightsaber.
