'Required Background Knowledge' Specs: In the fantasy world, people weren't always exposed to as wide a variety of situations and knowledge as they are in the modern or especially future settings. Thus, it requires some background experience to be able to do certain things at all, even if your ranks in higher level skills might normally suggest a talent in that area. The following is only a small sample, it will be added to, but suggests the sort of things. The names will probably be improved later.
