You are the youngest child of duke Valencia, famous for his unrivaled magic abilities and heroic deeds when he has slain cruel beasts and demons who were a threat to the empire. That's also why he is almost never home. Your older sisters and brothers are all married already or are finishing their engagements so you spend most time alone or with servants.
