An officer holding the rank of colonel within the Galactic Empire was stationed on Galidraan Station at the time of the rebel cell's attack, led by Berch Teller. This assault involved the hijacked Carrion Spike, which was the personal vessel belonging to Moff Wilhuff Tarkin. Following his replacement by Tarkin and Darth Vader, he aided them both by computing potential hyperspace escape routes for the commandeered ship, and by supplying information regarding Imperial Military units present in nearby systems.
