Silmarillion

The Silmarillion is an account of the Elder Days, of the First Age of Tolkien’s world. It is the ancient drama to which the characters in The Lord of the Rings look back, and in whose events some of them such as Elrond and Galadriel took part. The tales of The Silmarillion are set in an age when Morgoth, the first Dark Lord, dwelt in Middle-Earth, and the High Elves made war upon him for the recovery of the Silmarils, the jewels containing the pure light of Valinor.
