Silmarillion - A Vintage Fantasy Novel Book (Prequel to LOTR) by J.R.R. Tolkien

The story of the creation of the world and of the First Age, this 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 three Silmarils were jewels created by Fëanor, most gifted of the Elves. Within them was imprisoned the Light of the Two Trees of Valinor before the Trees themselves were destroyed by Morgoth, the first Dark Lord. Thereafter, the unsullied Light of Valinor lived on only in the Silmarils, but they were seized by Morgoth and set in his crown, which was guarded in the impenetrable fortress of Angband in the north of Middle-earth. The Silmarillion is the history of the rebellion of Fëanor and his kindred against the gods, their exile from Valinor and return to Middle-earth, and their war, hopeless despite all their heroism, against the great Enemy.
