Korr U'Raath is the older brother of Jag U'Raath and like other members of Clan U'Raath, Korr joined in the fight against the Yuuzhan Vong when Boba Fett rallied the Mandalorian people against the invading horde. He was known for using incendiary weapons against large groups of Yuuzhan Vong warriors during battle, taking a grim joy in watching the Vong burn.
