During the time of the Galactic Empire, the human led a successful career as an Imperial TIE pilot. They were assigned to Empire's Dark Squadron under the callsign "Dark Four" between 3 ABY and 4 ABY. Reporting to the Sith assassin Ochi of Bestoon, the squadron flew TIE defenders and were stationed aboard the Executor-class Star Dreadnought Executor, the Sith Lord Darth Vader's flagship. Dark Squadron was placed under the command of the cyborg Beilert Valance, "," who had been captured and forced into service by Vader. The squadron was then given the mission of eliminating the Imperial Admiral Tarl Sokoli, who was alleged to have become a mole for the Crimson Dawn syndicate.
"Dark Four" and the rest of their squadron traveled to Sokoli's light cruiser, the Forerunner II, outside the Eriadu system, the cruiser having been redirected under Vader's orders. Valance had the squadron begin its attack immediately as the cruiser began deploying TIE fighters. With "Dark Three" feeling uneasy about fighting other Imperial pilots, Dark Four reminded them that the mission had come from Vader, asking if the other pilot wanted to raise the issue with the Sith Lord himself. As the battle raged on, Dark Four made picked off TIE fighters, one squadronmate commending their shooting. The pilot also heard Lieutenant Jeela Brebtin "Dark Two" scorn for not calling her by her callsign.

Dark Three was soon killed by the Forerunner IIs cannonfire. "Dark Five" iterated the words "kill" as they shot down TIEs, leading Dark Four to question where the Empire had found the other pilot. Brebtin told Dark Four to focus on the battle, the latter complying and having to correct themself when not using "Dark Two." Valance backed the lieutenant, telling Dark Four to focus on the crossfire ahead. Dark Four did not listen, bragging that they were one of the Empire's best Imperial pilots for a long time. However, the a TIE fighter cut off the pilot by destroying them and their own fighter. Despite Dark Squadron's losses, Valance was able to kill Sokoli himself, completing the squadron's mission.
