Lassi

A strange little fellow who guided Souma and Elwyn through an icy blizzard. He guided the group to Celestia through a secret opening in the forest to the north of Philias. There, he is revealed to be the Spirit King of the Wind. He has an affinity towards elves who can strangely understand him. After Celestia, he joins Xecty in Baelgard, to restore the forest to its former glory. source: wikipedia
