At just eighteen years of age, Keir became the leader of the army fighting against the usurper king while Princes Edan and Egan led the navy. At his side, willing to help from time to time, was Sprite.
A friendly ghost, Sprite likes to keep Keir company and occasionally play tricks on Keir's sister. When the Oracle demands Keir's presence, he expects Sprite to travel with him.
He doesn't expect the gale that knocks him overboard and into an adventure that might just kill him.
