Mananan (マナナン) is a character from Fire Emblem: Genealogy of the Holy War. He was the brave King of Isaach before the events of the game, and is the father of Mariccle and Ayra. After the Rivough clan attacked the free city of Darna in the Yied Desert, Mananan set off in an attempt to resolve the situation. He led an army to defeat Rivough and slayed the Rivough ruler (who might have been one of his relatives, plus was the father of Galzus), offering said region to Grannvale in a bid to propose a truce. However, Mananan was captured by Grannvale's soldiers and executed by Reptor, resulting in the continuation of the Isaacian-Grannvaleian war. Manfroy was the mastermind behind Mananan's death, scheming with Lombard to attain more power for themselves.
