Tarrant Snil served as an Imperial official responsible for customs enforcement, stationed in Lay Pa-Sidian located on the planet G'wenee. To gain favor with the Hutt known as Grappa, Kir Kanos apprehended Snil, presenting himself as the bounty hunter named Kenix Kil. After delivering Snil back to Grappa, Snil was then given to the savage Zanibar.
