Shan Tanner was a moisture farmer on the planet Tatooine. He was the son of Jahn and Lania Tanner and lived on the Tanner Ranch in the Western Dune Sea. Tanner typically dressed in a tan tunic with blue leggings and a canvas hat.
Tanner encountered a group of spacer who crashed near the ranch in the middle of a sandstorm. Shortly after, Tanner, his family, and their farmhands were forced to relocate to Wayfar in the face of a marauding force of Tusken Raiders.
