Idun

Idun occasionally visits the Fairy Village to deliver golden apples, which are known to have medicinal properties. She meets the protagonist who requests some of her apples, but she tells him that the ones she has on her aren't ripe and that Loki had been stealing some of them from her. After finding some missing apples, Loki ends up kidnapping Idun, prompting a Jack Frost to commission the protagonist to rescue her. The protagonist defeats Loki and frees Idun from her prison, upon which she returns to the village. Idun, also spelled Idunn, or Iduna (Old Norse: Iðunn), is the Norse goddess of apples, youth, spring and rejuvenation and the wife of Bragi, the god of poetry. She was the keeper of the magic apples of immortality, which the gods must eat to preserve their youth, and so was treated as a granter of eternal youthfulness.
