In Norse Mythology, Idunn is a goddess associated with apples and youth as well as being a member of the Aesir. She tended and guarded the Apples of Immortality, magic apples that kept the gods from aging. She was known as the granter of eternal youth. Iðunn is mentioned in the Poetic Edda and the Prose Edda. In both sources, she is said to be the wife of the god Bragi. Idunn is the custodian of the golden apples of youth. When the gods feel old age approaching, they only have to eat of the apples to become young again. As a goddess of fertility, youth and death, it is possible that she was originally one of the Vanir. Idunn was once abducted by the storm giant Thiazi and in this interval the gods began to age rapidly. She was eventually rescued by Loki who changed her into a nut and brought her back to her hall. The gods were restored to youth soon after.
