The Western Dune Sea was a quadrant of the Dune Sea on Tatooine. This area was separated from the Northern Dune Sea by the Jundland Wastes and the Great Mesra Plateau. During his time as a hermit on Tatooine, Obi-Wan Kenobi lived in a hut on the edge of the Western Dune Sea. The escape pod of C-3PO and R2-D2 landed in the eastern limb of the Western Dune Sea, with R2 setting the coordinates 40 kilometers south of its intended target.
