From the front cover: "Beneath the towering trees of ancient wood, beneath branches laden with the tired detritus of old growth live creatures of nightmare. In croaking tongues they call out one to the other, sounding the hunt. By stealth and subterfuge they hunt, stalking the unwary. They are predacious beasts, who care not for treasure or misspent wealth. These are the Miasmal Wyrms. New Dragons, along with their Habitats, Ecology and Magic along with new symbiotic creatures. A whole new way to look at Dragons!
