Valinor
Valinor, or Valinórë, is the realm of the Valar, centrally placed on the western island continent of Aman. It lies across the Great Sea Belegaer from the larger landmass of Middle-earth.
In the dawn ages, Valinor also became home to the Elves who sailed across the sea, while others remained in Middle-earth. Those who remained in Middle-earth retained a sea-longing, an innate wish to travel to the Lands of Light in the west, which had to be either heeded, endured or suppressed. This sea-longing has heavily influenced the culture and history of the Elven people.
Those Elves who beheld the light of Valinor and then returned to Middle-earth are known as High Elves. These are among the most revered of Elves in Middle-earth, and include such illustrious examples as Gil-galad, Galadriel, Glorfindel and Celebrimbor.
