Wiccan

Wiccans are a race of people that were mentioned in Scooby Doo and the Witch's Ghost.

History
As described by Velma and Ben, Wiccans were people who were in tune with the forces of nature, and used them for healing purposes. They believed in using herbs and other natural elements to draw on the Earth's power to heal the sick.

However, due to their non-traditional approach and eccentric ways, they were misunderstood and accused of sorcery. In fact, the word "witch" came from "Wicca".

It was later proven during the film that, because of their practice of utilising the forces of nature, Wiccans do have the ability to cast magic, though it appeared that they would require objects of great power, such as a book of spells. Thorn, because of her Wiccan descent, was able to utilise the magic of Sarah Ravencroft's spell book to banish an evil witch back to oblivion.
