The Lord Of The Rings is the grandfather of modern fantasy fiction. J.R.R. Tolkien created an entire world for fans to experience, one with its own cosmology and history. The Hobbit and The Lord Of The Rings tell the story of the West of Middle-earth, but a concept is introduced early in Fellowship Of The Ring - the Elves of Middle-earth leaving and sailing to the Blessed Realm in the West. For fans who have only read The Hobbit and The Lord Of The Rings or watched the movies, the Utmost West is a mystery. However, for readers of The Silmarillion, the land of Aman, as the Blessed Realm is called, is quite familiar.
