After a rudimentary amount of digging [which ended me up on a German 4chan of all places, where I swiftly backpedaled and returned to English-speaking sites] I think it'll be hard to find much in-depth information without personally owning a copy of the system, but the generalized information available was helpful in giving the cults a bit more distinction and comprehension. It'll make choosing a cult to make a character easier at the very least.
