If you were building a world (writing it for fiction or should you suddenly find yourself with great goddess/god-like powers) what would the religion of your world be?
Keep in mind that it doesn’t have to be anything connected to what you already know or have grown up believing. It doesn’t have to be good or evil or anything balanced. On some level it should make sense, after all people are following this religion for centuries so it had to have a reason and common ground for them in the beginning and still be something they have faith in now.
Don’t be all goodie goodie though. Don’t you really get tired of carrying around a full load of goodness and light everywhere you go? Park it awhile and invent the new religion!
