Kressis was a male Trandoshan who lived on the planet Almas during the waning years of the Galactic Republic, working as the lead harvester on a kaluthin farm ran by the farmer Rashen Sotose. In circa 31 BBY, Kressis was operating a harvester vehicle when the farm fell under attack from the Believers, an Almas-based Sith cult. Following the attack, the farm was abandoned and Kressis made his way to Building 49-A, Almas' only cantina. The Heroes of Cularin—a group of freelance agents that were investigating a Believer plot to poison all of the kaluthin on Almas—traveled to the cantina during the course of their investigation, and encountered Kressis.
