Underworld Lore #3 is the means to craft one serious Cimmerian campaign setting with added bits of unseriousness thrown in for good measure. James Mishler is largely to thank for the former aspect of this issue -- with both his detailed hex map of the country of Cimmeria (and surroundings) & his practical gazetteer that describes this landscape. Combine this with copious facts, myths and dark lore about the Hyborian Age and its peoples, creatures and gods and you have practically everything you need to explore the wilds of Conan's homeland in your next campaign. Well, minus the ruleset. That's up to you.
