What is the magic or witchcraft?

Well first off there is a difference between the two. Witchcraft is first and foremost a religion. Sorcery, like wizardry is the art of practicing magick. Through magick both witches and sorcerers try to change the outcome of any event by manipulating time, space, and nature. Unlike the witch though, a sorcerer can be of any religion. They can be a christian, a Jew, or a Muslim, and so on. A witch on the other hand can only be a witch if witchcraft is their religion.
