The "Hero for Hire" and aspiring legend joins the party and soon convinces them to take a detour to explore the ancient treasure caves of Mount Teratos. But, treasure is not the only thing said to be sealed away within the mountain's depths-it's also the place where the terrible Hellfire Lord Goramesh was imprisoned When Wolfie and Calvin let their curiosity get the better of them and release this sealed evil from his can, however, our heroes find that there is more to this his mythic rampage than scorched cities and an impressive body count. Can they get this ancient destroyer to warm up to them enough to change his evil ways? Or is his blazing temper just too hot to handle?
