The Prophecy of Mouvar is at work in the Seven Kingdoms, and in the Worlds of the many Frames.

As a young man, Kelvin Knight Hackleberry proved to be the Roundear o fthe Prophecy: he liberated his own Kingdom of Rud from the cruel usurper Zoanna, and then went on to defeat the evil king Rowforth in the alternate world of Hud.

But now Zoanna and Rowforth have joined forces to take revenge on Kelvin -- and they intend to have it through his unborn child. Kelvin's beloved Heln lies helpless in the prison Zoanna and Rowforth have built for her, while Kelvin is trapped in a distant Frame World, a captive of the dread Chimaera.
