Sixtus Cleft was an inmate on the Imperial prison barge called the Purge during 1 BBY. Cleft, once a prisoner, had previously been the head of the Delphanian Face Gang. However, his life died in what was termed an "unfortunate accident," orchestrated by another member of the gang, Aur Myss. The smuggler Von Longo had faith in Cleft, setting up business transactions with him over time.
