Technically he would be a Traveler.
The closest Native race would probably be Alfun. If it would be able to fit into the lore to have an Alfun with an Arctic theme, then I would be inclined to adjust my app towards that. So as of now he is just from some unknown locations in the tundra, maybe he first crossed into the Sanctuary realms via the Northern area and hibernated/floated down to Summer Isle where he thawed and awakened.
Edit: Changed the last name.
