Gilroy, the hideously ugly but charismatic fugitive Troll, is believed to be a monster most foul. With his faithful pet Hog, Bogey, an equally repugnant creature, he carries out his vile dastardly crimes hunting and trapping the tiny sprites in and around the magical woodland areas. Errol, the ever vigilant Sheriff of the woodlands, hunts Gilroy relentlessly day and night and Gilroy is forced to go into hiding in a great dark dank underground cave far below the forest land, known to be occupied by Drasilla, the queen of the vampire fairies. Although Gilroy rather recklessly and foolishly enjoys his gruesome notoriety, is he really guilty as accused - or is he just full of hot air. Nevertheless, Gilroy is determined not to be caught and together with some other equally weird characters who have befriended him somewhat involuntarily and who believe that he is not entirely the monster he is believed to be, set about keeping him safe and hidden from his would be captors.
