Norse
Idun
The keeper of the apples that keep the gods young.
In Norse myth Idun keeps the apples of youth that the gods eat to stay young. Our sources are mostly the Poetic Edda and the Prose Edda, written down in Iceland in the 13th century, long after the stories began.
In the best known tale, Idun is tricked away from the gods and they begin to grow old until she is brought back.
