The Deluvian fatworm, a species of worm, originated from the Deluvia system. This system was located within the Klina sector of the Outer Rim Territories', an area neighboring Hutt Space. These worms were parasitic organisms, known for attaching to the backs of sentient members of the Hutt species.
During 3956 BBY, the Jedi Padawan named Revan journeyed to Kashyyyk, a planet situated in the Mid Rim. There, he encountered Eli Gand, a merchant, along with Matton Dasol, his indentured servant. As Gand tried to entice Revan with his merchandise, Dasol cautioned Revan that Gand's loan interest rates would "drain" him, drawing a parallel to a Deluvian fatworm's parasitic behavior on a Hutt's back. Reacting negatively to this comparison, Gand retorted that the Hutts were entirely "ALL backside."
The Deluvian fatworm first appeared in the 2003 Star Wars: Knights of the Old Republic video game developed by BioWare. The game features the creature as a reference point during an optional dialogue between the player character, Revan, and the characters Eli Gand and Matton Dasol. The information presented in this article is based on the assumption of complete game progression, including the aforementioned conversation.
