Cassus Fett was a Mandalorian Field Marshal who lived during the time of the Mandalorian Wars. Fett was an aide-de-camp to Mand'alor the Ultimate, leader of the Mandalorians, and he was highly influential in areas throughout Mandalorian society. Fett spearheaded the promotion of the Neo-Crusader movement, a sect of Mandalorian society with a more regimented structure and standardized armor than the hitherto dominant Mandalorian Crusaders.
