Ok sloppers, I need your help. Here is the deal:

I need a short and sweet idea on how to approach it - I am making a cult in my D&D game, with my character being one of the three celestial warlock leaders of the pitifully small cult of a nameless empyrean trying to ascend to godhood. We recruit followers by going around the slums healing and curing the sick, offering shelter where the big churches turn their noses, etc. and stealing prayer energy from the big churches via our magical holy symbols. I need you to help me generate the the two other leaders - human male in this 40s and a weirdo gnome female in mid 20s. Also, I need ideas on how to make the visuals, as I am looking at something trying to pose as some knights templar wannabes, akin to the real life Order of the Solar Temple, that one weird French suicide cult (understandable, I'd also kill myself if I were French).

While the three go around and pose as clergy in other churches, I need ideas on how they look like. Here is my PC, and will drop some randoms that I've generated.
