The Kingdom of Munster is one of the four kingdoms of the Munster District, along with Leonster, Ulster, and Conote, and is the closest to the Thracian border. After the Aed Massacre, King Travant of Thracia took advantage of Leonster's crushing defeat and sent an army to conquer the Munster District, starting with Munster itself. Leonster's King Calf sent a large army to aid Munster, but they were betrayed by Raydrik of Conote and Leonster's army was annihilated, including Calf himself, at the Battle of River Thracia. Raydrik was later rewarded by the Grannvale Empire's Duke (later King) Bloom with the position of Duke of Munster when the Empire annexed the entire Munster District.
In Fire Emblem: Thracia 776, Leif was captured by Raydrik's minions and imprisoned in Munster. He was rescued by the Magi Squad, led by Ced, and escaped to safety. Much later, converging with the events of Fire Emblem: Genealogy of the Holy War, Leif joined with Seliph's liberation army after launching a direct attack on Munster Castle. After a difficult battle, Raydrik and his superior, Veld, were defeated by Leif and his supporters, allowing the liberation army to safely enter the south of the Thracian territory.
