Thaffe was an Imperial drill instructor. He was once a suspect in a murder, but was cleared by Spurch Goa, an investigator for Imperial Navy Intelligence. He became friends with Goa, and after retiring from the military the pair became Sector Rangers. During that time he trained Dyyz Nataz in counter-terrorism procedures. The three were captured and tortured by Ganks loyal to Jabba the Hutt. Thaffe sacrificed his life so his two friends could escape.
