Armchair Historians and Strategists are annoying. and most of them get their Information from PBS or History Channel. while i find entertainment in these documentaries myself. i don't take them as fact, because i know information warps over time and what might have been truth at one point might be considered myth later.
cold iron is expensive to make, and has to be made by hand without a forge and without coal. i don't know where these which hunters manage to get it all.
