The Dune Sea was a big, big, BIG, pile of sand on Tatooine. It stretched for vast distances and was pretty sad. Jabba's Palace was found in the northern area of the Dune Sea, with Obi-Wan Kenobi's home being in the southwest corner. The Sarlacc also lived deep in the Dune Sea. Banthas roamed the area, as well as Krayt Dragons.
