Annance held the rank of captain and commanded the Imperial CR90 corvette named Empire Forever. He was assigned to escort Imperial Advisor Coh Veshiv during a period of inspection during the Galactic Civil War.
In approximately 0 ABY, Captain Annance stood ready for the arrival of Coh Veshiv. Throughout his time in command, he gave instructions to all crew members to avoid engaging the Rebel Alliance since his sole mission was to transport Advisor Veshiv. As they traveled to Esseles aboard the Empire Forever, Annance became increasingly irritated by Veshiv's constant complaints about his preference to be on a cruiser rather than the smaller corvette for his inspection duties.
