The rejuvenating one

Idun, is a goddess associated with apples and youth. She is described as the wife of the skaldic god Bragi, and also as a keeper of apples and granter of eternal youthfulness.

The god Loki was once forced by the giant jatunn to lure Idun out of Asgard and into a wood, promising her interesting apples. Tjazi, in the form of an eagle, snatches Idun from the wood and takes her to his home. Idun's absence causes the gods to grow old and gray, and they realize that Loki is responsible for her disappearance.
