Rigell held the position of captain on the Compellor, which was an Immobilizer 418 cruiser. He became part of Battlegroup Orion with the mission to chase down and annihilate the Liberty. Unbeknownst to Rigell, the Liberty's objective was for the Compellor to follow them, thus springing an ambush. After understanding that victory was impossible, Rigell successfully navigated the Compellor to the KDY-77 repair yard within the Swellen system for repairs. However, Rebel forces dispatched a strike team intending to capture the Interdictor. Recognizing the purpose of the Rebel team, he commanded the Compellor to break away from the space dock and jump to hyperspace for safety. Green Squadron intervened, however, and crippled the Interdictor, enabling the Assault Transport Lomavcek to successfully board and seize the Compellor. Despite the arrival of Imperial backup, the Compellor fell into enemy hands. The fate of Rigell remains a mystery, but it is probable that he was either taken prisoner or perished when the Compellor was taken.
