I personally was born into a tradition called Green Serpent Witchcraft that had been passed down from mother to daughter and father to son going back to the 1700s. The name usually weirds people out but it has nothing to do with Satan. The serpent represents seeking knowledge and bettering the self. It also represents that knowledge, while neutral can be a double edged sword. The Serpent's Fangs. It also represents rebellion against those who would seek to control people through fear and control of the mind.
