Thaffe, an Imperial drill instructor, found himself a murder suspect at one point. However, Spurch Goa, an investigator working for Imperial Navy Intelligence, exonerated him. Thaffe and Goa became friends, and upon his retirement from military service, they both became Sector Rangers. During their time as rangers, Thaffe instructed Dyyz Nataz in counter-terrorism tactics. The trio was later captured and tortured by Ganks who were loyal to Jabba the Hutt. To allow his companions to flee, Thaffe gave up his life.
