Origin: Norse mythology
In Old Norse, elves were called Alfar. They were divided into two races: the Light Elves and the Dark Elves.
Light Elves, or Liosalfar, are radiant and beautiful beings who were ‘fairer to look on then the Sun’. They lived in a luminous realm called Alfheim which was located between Heaven and Earth. They were benevolent towards humankind, and marriage between human women were possible. Heroes could become Light Elves after death.
Dark Elves, or Docalfar, were said to be ‘darker than pitch’ and lived in kingdoms deep underground. There they used their magical powers to fashion swords and enchanted objects.
