- "Find Admiral Tarkin and bring him home."
- ―Emperor Palpatine to Darth Vader
Garoche Tarkin was a Human male who served in the Imperial Navy since the earliest days of the Galactic Empire. A scion of the wealthy and influential Tarkin family of the planet Eriadu, Garoche was the son of Grand Moff Wilhuff Tarkin. Shortly before his disappearance around 19 BBY, Garoche had reached the rank of admiral and was in command of a Imperial I-class Star Destroyer.
- "The vessel is under the command of this man...Admiral Garoche Tarkin...my son."
- ―Grand Moff Wilhuff Tarkin to Darth Vader
Following in the footsteps of his father, then-Moff Wilhuff Tarkin, Garoche Tarkin enlisted into a military academy, thus also keeping in tradition with his family's strong support for military service. While training at the Academy, he befriended his rival and fellow cadet Shale. By 19 BBY, he was serving the Galactic Empire as an admiral and commanding officer of a Imperial I-class Star Destroyer.
Barely after the fall of the Old Republic and the rise of the New Order, Admiral Tarkin was tasked with eliminating insurgents in the Ghost Nebula. However, the mission had apparently been a failure, resulting in the disappearance of both the admiral and his vessel. In order to find and retrieve his missing son, Grand Moff Tarkin requested the aid of Emperor Palpatine. Much to the dismay of Tarkin, however, the Emperor's Sith apprentice Darth Vader was tasked with the mission to find Garoche. In the event that Vader became distracted from his primary objective, as had happened in the past when faced with hunting down Jedi fugitives, Tarkin attached Captain Shale to the mission.
In actuality, Garoche defected to Atoa in part due to a deep resentment of the atrocities he had to commit in the name of Palpatine, and aided in its insurgency.
