A mysterious individual accompanied Souma and Elwyn during a snowstorm. They led them to Celestia via a concealed entrance within the northern Philias woodland. Upon reaching their destination, it was unveiled that this personage was none other than the Wind Spirit King. He possesses a unique bond with elves, who can somehow comprehend his enigmatic speech. Following Celestia's restoration, he ventured to Baelgard alongside Xecty, aiming to revive the forest to its previous splendor.
