Il de Hermantine was once Castle Hermantine, the governing center of the duchy of Hermantine once ruled by House Kitan and then by House Selis. During the civil wars, many refugees entered Castle Hermantine, which prompted it to be declared a city. When Duke Henry Selis began his series of campaigns to reunite the land, Il de Hermantine, as its name had been changed to, had suffered from constant attacks. With the unification, Il de Hermantine quickly recovered and began to become the center of governing the now formed Kingdom of Hermantine.
