Back in the day, "witch" used to be a word that people would slap on women who weren't acting the way they wanted them to, in order to get people to turn against that particular woman (indeed, a similar word is often used today for the same purpose). Sometimes the accusers were doing it to maintain control over women they thought were "uppity" and even men they found to be inconvenient. Other times they sincerely had worked themselves into a hysteria whereby they believed that witchcraft had caused their problems, and they honestly felt that they ought to attribute drought, a dead cow, or lack of success in love to Satan's earthly minions, the witches.
These days, we know how unfair and ridiculous this was. After all, today, a "witch hunt" literally means a politically motivated hunt to find enemies who don't exist or dump blame on innocent people. That's because witches aren't real! Or aren't they? We would all feel pretty darn silly if we found out that actually, the witch-hunters were right - about the existence of witches, at least, if not the specific identities of the people they burned at the stake.
Just in case they were onto something and acquiring witchy powers is possible, it's probably a good idea to know what your familiar will be. That's an animal that's real, but functions like a combination of a spirit guide and magician's assistant. What familiar you have depends on your personality, how powerful a witch you are, and the kinds of spells you would like to cast. Let's get started!
