Jared Cassel was a Human male born on Bastion to a pro-Imperial family. The brother of Gil Cassel, Jared joined the Imperial Army. Jared eventually reached the rank of captain and served in the 908th Stormtrooper Division, while Gil reached the rank of Lieutenant and served in the 407th Stormtrooper Division. Seven years after the start of the Second Imperial Civil War, the 908th defected from Darth Krayt's Galactic Empire and declared its loyalty to the deposed Emperor Roan Fel and his Empire, while the 407th remained loyal to Darth Krayt.
During the Battle of Borosk, Jared Cassel led the 908th against the 407th, commanded by the Sith Lord Darth Maleval and Jared's own brother. After the 407th's victory, Captain Cassel was spared from being killed and taken by Lord Maleval to be executed by Gil. Despite Jared trying to convince Gil to do it and save his own life, Gil refused, causing the Sith Lord to decapitate both of the Cassel brothers.
