Brother Hiob of Luzern, on missionary work in The East on the eve of the 18th century, stumbles across a miraculous tree whose fruits are books which chronicle the Kingdom of Prester John. This story recounts the fragmented narratives found within these miraculous volumes, revealing John's rise to power, from John's own viewpoint, from the viewpoint of his wife Hagia, and from the viewpoint of Hajji, a prayer-cantor who vowed to end John's illegitimate reign.
