Both the Galactic Republic and the Mandalorians known little of Cassus Fett's origin, only that he is human. Fett was one of the advisors called up by Mandalore the Ultimate to help him rebuild the Mandalorians after the Great Sith War and the death of the previous Mandalore. Fett was appointed top strategist by the new Mandalore. He was responsible for the incorporation of conquered races into their culture and also responsible for the incorporation of the ideas of the Neo-Crusaders, a splinter group of Mandalorians whose main ideas include wearing the same armor and having a structured chain of command. He also argued that the suits of armor they wore should be color-coded by rank. Lowest ranks wore blue while the highest ranked, such as Fett himself, wore gold. Fett has had a long standing rivalry between himself and Demagol (Which literally translates to sculptor of flesh or butcher) a Mandalorian scientist obsessed with jedi who is also one of the advisors recruited by. Demagol does not wear uniform armor to spite Fett. Fett was a major part in the Mandalorian invasion of the Republic and even more crucial to the invasion of the planet Taris. Fett would later fight Revan and Malak at the Battle of Jaga's Cluster,where he became famous for killing the captain of a Republic frigate flagship. After this and the fall of the Mandalorians Fett became the most wanted man in known space and was eventually presumed dead.
