Quinlan Vos was a male Kiffar Jedi Master in the Jedi Order and a General in the Grand Army of the Republic during the Clone Wars against the Confederacy of Independent Systems. He hailed from the planet Kiffu in the Inner Rim. With long, dreadlocked hair and a band of pale yellow across his upper face, Vos was gifted with psychometric powers which allowed him to "read memories" from inanimate objects through physical contact.
Vos had an ongoing struggle with the dark side of the Force, particularly after he sustained recurrent amnesia after he overdosed on an illegal drug administered by an enemy shortly after the Battle of Naboo. The Sith Lords Darth Sidious and Darth Tyranus both showed an interest in him, and while Vos served Dooku for a while, he eventually redeemed himself and was readmitted into the Jedi Order. As the war continued, Vos served on numerous missions, including the hunt for the Hutt crime lord Ziro Desilijic Tiure. Throughout the war, Vos was openly disdainful to the clone troopers under his command, which lead to him being disliked by clones and hated by Sergeant Kal Skirata.
Vos was on Kashyyyk as part of the battle there when Supreme Chancellor Palpatine, in reality the Sith Lord Darth Sidious, issued the order to clone troopers to kill their Jedi superiors. Despite serious injuries, Vos escaped as one of the few survivors of the Great Jedi Purge and settled on Kashyyyk with his lover, Khaleen Hentz, and raised a son named Korto Vos.
