This little paradise was a happy place. Odin and the other gods often visited, marveling at Iduna’s kindness and delighting in her humor and her wit. Yet there was another reason that they came; Iduna possessed a special treasure — a golden chest of magic apples that kept all those who ate them ever young. Truly it was the precious fruit that kept the gods immortal. Odin knew the value of these apples. He never ventured on a journey without a few to take along.
