Worr Muugyn, a youthful Mandalorian, participated in the Mandalorian Wars. On Vur IV, amidst a clash between Mandalorian and Jedi combatants, Muugyn disregarded instructions to retreat from the planet when the Jedi reorganized within a demilitarized zone. Instead, he gathered willing soldiers to reinforce a strategic location called Blood Ridge. Muugyn, alongside his adherents, then launched an offensive against the Jedi, successfully enduring the Battle of Blood Ridge. He continued to command Mandalorian troops until his death in combat in 3959 BBY.
