Witch

A Witch was a (usually female) practioner of magical arts, though not all magicians would have consider themselves witches.

Some used the term "wizard" to refer to a male witch (DW: The Dæmons) others used witch to refer to practioners of both sexes.

Less advanced cultures had a certain fear of paranoia and would sometimes mistake psychic powers or advanced technology as witchcraft.

History

Alien entities, the Fendhal (DW: Image of the Fendahl) and the Dæmons (DW: The Dæmons) undoubtably affected Humanity, specifically Human notions of witchcraft.

As late as the 20th century, in England, witches both "white" (benevolent) like Miss Hawthorne (DW: The Dæmons) and evil, still formed covens. (DW: Image of the Fendahl, A Girl's Best Friend)

In the early 21st century, neo-paganism gained in popularity. (NA: Cat's Cradle: Warhead)

The Travellers of the 26th century respected a similar ethos and honored ancient gods.

Self-named Witch Kids, rejecting technology and knowledge and glorying in violence, spread across the United States. (NA: Cat's Cradle: Warhead. DWM: Ravens)
