The silmarillion

The forerunner to The Lord of the Rings, The Silmarillion tells the earlier history of Middle-earth, recounting the events of the First and Second Ages, and introducing some of the key characters, such as Galadriel, Elrond, Elendil and the Dark Lord, Sauron. 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.
