What do you mean by world building? Honest question.
I’ve had some contact with wiccans, pagans and other people that held belief in the supernatural and watched some of rituals but I don’t know what to tell you that may go into what you are looking for.
I understand. Thank you for the clarification.
And, not to deter you from your goal, you have a lot to pick from.
There is a lot of background from which you can pick and build from but what would be the end result you are envisioning? I can tell I got to know a particular “tradition” where no rituals exist; initiates undergo a sort of tutelage under more experienced individuals but at some point it is supposed for each individual to set out their own path. No dogma, no saints, demons or higher powers; they just take the universe as a power source and it is the people tapping into it that can use it for “good” or “bad” endings.
The wiccans I got to know were essentially neo pagans, drawing from a favourite personal pantheon and ancient culture. I knew a Neo-aegiptyian priestess, a couple of neo-druids, a neo-norse shaman, one new age witch and one neo-meso american priest. Each just associated with an ancient culture they most closely identified with and delved into it. I watched magic circle drawing, offerings of food and items to gods and even assisted in a ritual of personal sacrifice, through fasting, sweating and intense physical exertion.
But I sense this is not what you expect as information. Feel free to pose more specific questions.
