Anyway, here are some bits of the project. The idea is that orcs are amphibious and they live in one huge interconnected cave complex that is partially under water and they are loosely organized into a whole bunch of cults who worship everything from the big amphibious monsters that they share their caves with, to the "Ancients" who long ago lived in a city which is entirely buried and coincidentally right under the Orc Cave.

(you can note which color die is for which column right there on the chart) I've used this (during play) and it works pretty well and quickly. Each cult has at least one scheme and maybe some rituals... and an enemy cult or two.
What I'm setting up here is for the Characters to get involved in all sorts of nefarious cult schemes, and kooky cult politics, kinda like this:
