The protagonist grew up as an orphan with no memories of her parents, raised by a family acquaintance alongside their son Renaud. When Renaud goes missing and no one nearby is willing to search — too frightened by the ongoing wars — she goes herself. She finds him serving as one of the knights of a man named Leviath. Choosing to stay close rather than lose him again, she gradually discovers that she carries a mysterious power Leviath's cause requires — and that uncovering it means uncovering the past she has never been able to access.
