Sir Gregor made a name for himself as a monster slayer after returning from the Crusades. Unfortunately, most of the "monsters" have been strange animals that do not pose much of a threat to anyone. Desperate for an opportunity to prove his worth, Sir Gregor and his entourage pay a visit to a wise hag that furnishes a map to the Devil's Cave. Sir Gregor, invigorated by the prospect of facing the greatest evil on earth, sets out on an adventure that proves fraught with dangers... not only physical dangers but spiritual as well.
