Digging a little deeper, I learned that Wicca is a religion that is centered around honoring nature and the cycle of the year. There are eight holidays in the Wiccan religion; two solstices, two equinoxes, and then four other sabbats throughout the year.
Wiccans believe that there is a common universal force that exists within everything and that this force can be manipulated through a person's will alone. This manipulation is the basis for Wiccan magic.
Wiccans believe in the threefold rule, believing that whatever they send out into the universe, go or bad, will come back to them threefold. They also believe to "harm none".
It is strange to me that such a seemingly peaceful religion is so often associated with worshiping the devil. Further reading reveals that Wiccans do not even believe in the devil or any personification of good or evil.
So now I have to question if my characters will be Wiccans or the more traditional form of witches...Oh, decisions, decisions.
