The Book of Lost Tales
But now even as Varda is engaged in this great work, behold, Oromë pricks over the plain, and drawing rein he shouts aloud so that all the ears in Valmar may hear him: “Tulielto! Tulielto! They have come - they have come!” Then he stands midway between the Two Trees and winds his horn, and the gates of Valmar are opened, and the Vali troop into the plain, for they guess that tidings of wonder have come into the world. Then spake Oromë: “Behold the woods of the Great Lands, even in Palisor the midmost region where the pinewoods murmur unceasingly, are full of a strange noise. There did I wander, and lo! ’twas as if folk arose betimes beneath the latest stars. There was a stir among the distant trees and words were spoken suddenly, and feet went to and fro.”
