The book concentrates on the realm of Middle-earth and comprises such elements as The Quest of Erebor, Gandalf’s lively account of how it was that he came to send the Dwarves to the celebrated party at Bag-End; the emergence of the sea-god Ulmo before the eyes of Tuor on the coast of Beleriand; and an exact description of the military organization of the Riders of Rohan.
Unfinished Tales also contains the only story about the long ages of Númenor before its downfall, and all that is known about such matters as the Five Wizards, the Palantíri and the legend of Amroth. The tales were edited by Christopher Tolkien, who provides a short commentary on each story, helping the reader to fill in the gaps and put each story into the context of the rest of his father’s writings.
