Well, the manual mentions King Solomon's Mines when talking about them. A hybrid grind-up of pulp fiction about the 'lost tribes of Darkest Africa', perhaps? The evil sorcerers ruling from an extinct volcano and the giant spiders with associated cult fit right in.

Omnirizon: I agree about the grind-up. The various Eskimo tribes probably get fed up that they're all called Inuit, too. And all those Celts, Angles, Saxons, Normans (and Vikings, Romans etc...) probably get annoyed at being lumped together as English these days.
