Here's something that I've found very useful in my games (WFRP2 and WFRP3): all careers have some kind of 'larger organization' to go with them. It seems like it makes the GM's job easier than just the "generic career." Anyways, here's my list, let me know if I missed any. Note: they all reference WFRP2 info:
