A human Imperial officer holding the rank of admiral served on the Executor, which was the flagship utilized by the Sith Lord Darth Vader during the Galactic Civil War. This admiral was aboard the Executor sometime between 3 ABY and [4 ABY], when it transported Vader and his Sith Master Darth Sidious to the Amaxine Station. The two Sith were traveling there to potentially confront an ancient Sith Lord who Lady Qi'ra, the leader of the criminal syndicate Crimson Dawn, allegedly planned to release from the Fermata Cage.
Once the Executor reached the station, the Emperor commanded the vessel to obliterate it. However, before this order could be executed, the Dawn Fleet emerged from hyperspace. The Crimson Dawn ships then began targeting the Executor's long-range cannons, aiming to prevent the station's destruction. The admiral informed Sidious that, while the Crimson Dawn fighters themselves were not a significant threat, their specific targeting of the long-range weapons forced the Executor to redirect power to the shield batteries. This, in turn, would cause a slight delay in fulfilling the Emperor's command to destroy the station. When Sidious inquired about the length of this delay, the admiral reiterated that it would be slight. Consequently, the Emperor instructed the admiral to ready a transport so that he and Vader could travel to the station themselves.
