Angel
From DALpedia
Angels are servants, workers, and citizens of the purely peacefully dimension known as Asgard. This is place is known to be where the souls of the truly pure of heart would go; very few earn the privilege to get to such a place.
Angels mostly assume the form of a humanoid, with white feathery wings, and perhaps a halo above their head. They have an unlimited life span, in Paradise, yet in other dimensions they have been known to deteriorate with age.
