Product Details:

• 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.
• This deluxe slipcased edition contains the complete text, which is printed in two colors and features, for the very first time, more than 50 color paintings, illustrations and designs drawn by J.R.R. Tolkien himself as he composed this epic work.
• Unique to this edition are two poster-size, fold-out maps revealing all the detail of Beleriand as the tales grew, an illustrated booklet featuring ‘A Brief Account of The Silmarillion and its Making’ by Christopher Tolkien, and a printed art card reproducing ‘Taniquetil’.
