My homebrew has several major pantheons and religions. Primarily it is dualistic, a principle good creator and an adversary, but this belief system is broadened by a celestial court that preforms the day to say actions of creation, some of which are worshoped as gods. This is heresy in one religion attached to the pantheon, and encouraged by another. Seperate from this pantheon is a broad group of nature gods worshiped by the nomadic szvagany (gypsy like humans) and the older human cultures. There are remnants of previous ages, a god or two from a mostly destroyed culture that survive. There are several independent gods which do not fall into any of the pantheons as well.
