My post is just a friendly advisement. Like those big orange barrels at the roadside or construction tape around a big hole in the ground. In this case, we're on ground that could quite easilly drift into Touchy Topic Land. The OP has a fascinating idea that can enrich the gameworld, and it brings other ideas to mind. How have the Massai dealt with supernatural predators, for example?
I just wanted to ensure we don't wander into direction of real life commentary on social/political issues. Thread drift being what it is, think about how often a mention of Robin Hood turns brings up comments socialism, captialism, etc. Or how often a question about Michael's sword turns into a discussion or even snarky arguement on various interpretations of Christianity, predestination, and high fructose corn syrup. So we need to be careful where we let our rambling lead us. Imagine Larry Fowler getting a hold of it, taking it out of context and saying "New Harry Dresden game teaches children to be suicide bombers!"
