Xarga was a drill instructor, a Mandalorian male of the Human species, who served as part of Mandalore the Preserver's forces during the Mandalorian Wars. He donned yellow Neo-Crusader armor, a color and style indicating his status as a high-ranking Mandalorian warrior. He tasked Meetra Surik with the retrieval of Kumus's equipment, believing Kumus to be dead after he had been missing in the jungle for 3 days. Surik came back with Kumus alive, who, unknown to Xarga, was simply stranded above a potential cache booby-trapped with explosives, guarded by Bomas until Surik eliminated them. Xarga fought in and lived through the Sith assassins' attack on the camp, and seemingly noticed and remarked on Kumus' combat prowess. In the Second Battle of Onderon, he aided Surik's allies in overcoming the Sith forces on Dxun.
Outside of established canon, Surik has the option to eliminate Kumus and return solely with his gear, as originally instructed, without Xarga realizing Kumus's survival. Conversely, the player can inform Xarga of the reason for Kumus's continued existence, elaborating on his loss of ammunition and the "dishonorable" circumstances of his predicament.
