Secret agent Gary wakes from a dream in which cultists of the Dark Brotherhood map out their plan for world enslavement. This seems like the kind of thing that requires immediate action. Gary, noting that he is technically on vacation, decides it can wait until morning. In the morning he contacts his boss Lucy and receives the official assignment. The investigation leads him to the gloomy Chateau de la Bourbon, then outward to its surroundings, then into a parallel world, and finally toward a confrontation with the ancient evil the Brotherhood has been preparing to summon.
