Chalmer Trillili was a Human individual of the male variety who existed throughout the era of the Galactic Civil War.
For a time, Trillili was a member of the Rebel Alliance; however, he ultimately abandoned his post and established The Scourge, a minor pirate organization that conducted operations within the Elrood sector. Trillili served as the captain of the Impasse, a Super Transport VII container vessel manufactured by Kuat Drive Yards that The Scourge outfitted with a gravity well projector. In addition, he possessed ownership of the Personal Profit, a significantly altered YT-1300 light freighter. Trillili's actions attracted the interest of the Khuiumin Survivors, another pirate faction. The Survivors subsequently sent Trillili a message, extending an invitation for him to become a part of their group. At approximately this point in time, The Scourge successfully captured the Gray Griffins, a scout team belonging to the Rebel Alliance. The pirates then tried to demand a ransom in exchange for the team's release. Nevertheless, a team of Alliance operatives journeyed to the Scourge's headquarters, situated on the planet Dega, with the intention of rescuing the Griffins. Trillili sought refuge within his private chambers, where the agents located him and subsequently engaged the pirate chieftain in armed conflict.
