Jack Deth returns for another round against the trancers. Jack must navigate his way home from Orpheus's alternate realm, where magic exists and the trancers were the ruling class (before Trancers IV, that is). Regrettably, Jack's attempt to locate the legendary Tiamond in the Castle of Unrelenting Terror may be hindered by the return of Caliban, the trancers' ruler who was believed to be dead.
