Cumberlayne Aresko, operating number: "LRC-01", was a human male who served as an officer in the Galactic Empire. In 3272 LY, Aresko held the title of Commandant and was stationed in Capital City, on the planet Lothal. Along with Taskmaster Myles Grint, he was charged with training cadets at the local Imperial Academy. Along with Grint, he once tried to arrest the merchant Yoffar for treason, but a timely distraction by Ezra Bridger saved Yoffar from a possible bad end.
Aresko, along with Grint, attempted to stop the activities of the rebel crew of the Ghost on numerous occasions, employing ineffective tactics that often failed due to Aresko's overconfidence and lack of tactical ability. Due to their multiple failures, they were executed by The Inquisitor, on the orders of Grand Moff Tarkin.
