- "Men, this mission is everything. It will win Quesh for the Republic. We will be immortalized as heroes!"
- ―Captain Trey-yen
In 3641 BBY, Captain Trey-yen led a strike team on the planet Quesh to place explosives in order to bring down a Sith outpost from below. When the Darth Baras' apprentice interrupted Trey-yen and Corporal Anders, Trey-yen attempted to detonate the explosives in order to destroy themselves the Sith Lord, but for reason unknown to him the bomb failed to detonate. The Sith Warrior proceeded to kill Trey-yen and his entire squad. After his death, the Warrior discovered that Lord Draahg had the real detonator, which he then used in an attempt to kill and bury the Warrior, since Darth Baras had foreseen that his former apprentice would soon overthrow him.
