Magic is not the exclusive Domain of those who make a religion out of it. Magic is not dependent on worship~ it exists anyway. Sacrifice to it or don't, make a coven or a cult or a secret society or a church, or don't. Gather together to increase the power of the energy, of the connectivity, it will work whatever you call it; it's physics. The power of belief and collective focus is still physics. It is natural. It just is.
Not all who wander are lost.
