|Location||Far East of Middle-earth|
|Description||Ancient land around a lake|
|Etymology||Q. cuiviër "awakening" + nen "water"|
Cuiviénen is the land where the Quendi or Elves awoke. Its name (cuiviër + nen) means 'water of awakening,' and it is said to have been on the shore of a large gulf in the inland Sea of Helcar in the far east of Middle-earth.
Eru first awoke the Elves there in approximately 1050 of the Years of the Trees. From the first they were divided into three groups: the Minyar, Tatyar, and Nelyar. They dwelt in Cuiviénen for more than five hundred years of the sun before the first sundering. Many of the Elves, particularly of the Minyar and Tatyar, journeyed west to Valinor and, if they did not tarry in Middle-earth, saw its light and became known as the Eldar. Those who remained were called the Avari, the unwilling, for they did not desire to see the beauty of that land, but preferred the starlight of Cuiviénen.
