"Through the Music of the Ainur, Ilúvatar created a Vision of the World," Legolas began, his throat dry. "The past, the present, and the future did not yet exist. He showed the Ainur what the world would one day become, granting them the gift of foresight, and explained much of the universe's destiny. The Ainur possessed immense knowledge of the world, yet they were not omniscient. So, Ilúvatar made the world real. Melkor and many other powerful Ainur desired to dwell there and prepare for the coming of Ilúvatar's Children, Elves, and Men. The Ainur, who had entered the world at its inception, then swore to remain until its end."
