Norse dwarves
The Norse dwarves are highly significant entities within Norse mythology. They are the makers of most of the artifacts of the gods, both Aesir and Vanir. Their dwelling places is one of the nine worlds upon the world-ash Yggdrasil, Nidavellir.They are often identified and seem to be interchangeable with the Svartalfar (dark elves) and the trolls.
J. R. R. Tolkien got some of the names of the Dwarves in his books from Norse mythology: Dwalin, Nain, Dain, Bifur, Bofur, Bombur, Nori, Thorin, Thrain, Fili, and Kili.
