I'm currently looking to set up an Age of Apostasy campaign as something a little different. Obviously there are gaps to be filled in. I have all of the rulebooks, from my beloved 2nd edition through to 5th (and a copy of RT of course). Are there any other sources out there with more info in, I know the 2nd edition Sisters of Battle has some stuff in, but what about the later Witch Hunters book? What else is out there that I should be looking at? Thanks very much in advance.
