The Silmarillion

For the first time ever, a beautiful slipcased edition of the forerunner to The Lord of the Rings, illustrated throughout in colour by J.R.R. Tolkien himself, with the complete text printed in two colours and with many bonus features unique to this edition.
The Silmarilli were three perfect jewels, fashioned by Fëanor, most gifted of the Elves, and within them was imprisoned the last Light of the Two Trees of Valinor. But the first Dark Lord, Morgoth, stole the jewels and set them within his iron crown, 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 the heroism, against the great Enemy. 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 book also includes several shorter works: the Ainulindalë, a myth of the Creation, and the Valaquenta, in which the nature and powers of each of the gods is described. The Akallabêth recounts the downfall of the great island kingdom of Númenor at the end of the Second Age, and Of the Rings of Power tells of the great events at the end of the Third Age, as narrated in The Lord of the Rings.
