This the the Beast of Ramoro, a Conan story with a dark, Halloween-appropriate theme (and rather dark lighting! Hopefully that isn't too much a problem.)
The big barbarian, in search of a man taken from a nearby village, enters a volcanic crypt a day's journey away. It's there that he finds not only the lithe blond victim, but Vulg, a carnivore mentioned only in hushed whispers throughout the region.
