Norse Mythology is the collection of the sagas of Scandinavia. Most of it is found in the Poetic and the Prose Edda. J.R.R. Tolkien borrowed many concepts and storylines for his own Legendarium, like the Shieldmaiden and the names of the Dwarves (from the Völuspá). Elves also appear in the Norse sagas, but they are altogether different from Tolkien's Elves; in most cases they are evil or just malevolent.
