A large collective of many people, ideas, groups,etc, that are illuminated. They can range from the average homeless drifter, to the most powerful businessman or occultist. They are everywhere in society and are impossible to destroy or entirely get rid of. There is no main unifying factor and they may dispute things amongst themselves or even fight for supremacy over one another. Some are benevolent, some are malevolent, and some don't care either way.
The Illuminati is everywhere and all seeing.
