In J. R. R. Tolkien's Middle-earth, the Moriquendi -- the Elves of Darkness -- are, in essence, the Elves that did not cross over the sea and behold the light of the Two Trees in Valinor. They lingered on the shores of Middle-earth or, indeed, never passed the Blue Mountains on the east of Beleriand or the Misty Mountains further to the east.
- "Those Elves the Calaquendi call the Umanyar, since they came never to the land of Aman and the Blessed Realm; but the Umanyar and the Avari alike they call the Moriquendi, Elves of the Darkness, for they never beheld the Light that was before the Sun and Moon."
