Idun is the gooddess of youth from Aesir. Her husband is the god of poetry, Bragi. The owner of Asgard Garden, in charge of rejuvenating apples. She is the daughter of Ivald, the dark dwarf with the most powerful magic in the underground city. She is beautiful and her father cast a spell to keep her young forever.

ldun is unanimously loved by the Aesir gods, and her beauty is also one of the best among the Aesir gods. The goddess of fate, Norn, gave the youth apples from the tree of life to ldun for safekeeping. The Youth Apple is the treasure of the Aesir Protoss. It can keep the gods young. It is also called "Idun's Blessing",but it must be picked by Idun herself and placed in an ash box before giving it to the gods. Idun was dedicated to guarding the Apple of Youth, and the gods were able to rest assured.
