A new edition of J.R.R. Tolkien’s The Silmarillion is coming this year alongside the launch of Amazon’s much-anticipated fantasy series, at least in the UK. The new book arrives October 27 and, for the first time ever, it’s been illustrated in color, with drawings from Tolkien himself. The entire text is printed in two colors as well.

For those catching up, The Silmarillion is a dense and detailed accounting of Middle-earth’s history. It serves as an explanation of the backdrop for The Hobbit and The Lord of the Rings. Among the book’s many stories are an accounting of the fall of the island kingdom of Numenor, titled Akallabeth, and a passage called Of the Rings of Power and the Third Age, which sets up the stories to come. Another popular chapter in The Silmarillion is Beren and Luthien, a love story about a mortal man and an immortal woman that is said to have inspired the storytelling of Aragorn and Arwen’s love, and the love between Tolkien and his wife, Edith. Tolkien passed away before he finished The Silmarillion. His son, Christopher Tolkien, finished the work.
