Sigurd is the first-generation protagonist of Fire Emblem: Genealogy of the Holy War. He is a Grannvalian prince and the lord of Chalphy who becomes the central playable figure in the game's opening generation.
The story begins in the year 757 of the Grann calendar, when Verdane invades Grannvale while the kingdom is weakened by events elsewhere. Sigurd responds by raising an army, rescuing his childhood friend Edain, and becoming involved in a conflict that spreads across the continent of Jugdral. His campaign introduces the game's major political alliances, romances, and the ancient legacy of the Twelve Crusaders.
Genealogy of the Holy War is structured around two generations. Sigurd leads the first, while his son Seliph becomes the principal hero of the second. Deirdre is a major character and Sigurd's wife, but not the first-generation protagonist; Arvis is a powerful political and military figure who opposes Sigurd. The generational structure is one of the game's defining features and directly connects its personal drama to Jugdral's long historical conflict.
