In Norse mythology, the Álfar, or Elves, are usually considered to be the height of humans or just above. The Light Elves are supposedly fair to look upon, and they live in Álfheim.
The Svartalfar (Dark Elves) live in the dark, and are slightly more mischievous. They are often associated with Dwarves.
The Eddas tend to use Álfar and Vanir interchangeably.
