Alfheim The home of the light elves.

One of the Nine Worlds of Norse mythology, according to Snorri Sturluson in his Gylfaginning. Alfheim was located at the top of the world tree, Yggdrasil, with Asgard, the home of the Aesir, and Vanaheim, home of the Vanir.

According to the poem Grimnismal, part of the Poetic Edda, in very ancient times the gods gave Alfheim to the god Frey, who was sometimes connected with elves, as a gift when he cut his first tooth.
