First Age Quotes

“Those of the Elven-race that lived still in Middle-earth waned and faded, and Men usurped the sunlight. Then the Quendi wandered in the lonely places of the great lands and the isles, and took to the moonlight and the starlight, and to the woods and caves, becoming as shadows and memories, save those who ever and anon set sail into the West and vanished from Middle-earth.”
― J.R.R. Tolkien, The Silmarillion
