In European folklore and folk-belief of the Medieval andEarly Modern periods,familiar spirits (sometimes referred to simply as "familiars") were supernatural entities believed to assist witches andcunning folk in their practice of magic. According to the records of the time, they would appear in numerous guises, often as an animal, but also at times as a human or humanoid figure, and were described as "clearly defined, three-dimensional… forms, vivid with colour and animated with movement and sound" by those alleging to have come into contact with them, unlike later descriptions of ghosts with their "smoky, undefined form[s]".

When they served witches, they were often thought to be malevolent, while when working for cunning-folk they were often thought of as benevolent (although there was some ambiguity in both cases). The former were often categorised as demons, while the latter were more commonly thought of and described as fairies. The main purpose of familiars is to serve the witch or young witch, providing protection for him/her as they come into their new powers.

Since the 20th century a number of magical practitioners, including adherents of the Neopagan religion of Wicca, have begun to utilise the concept of familiars, due to their association with older forms of magic.

Tasks and Assignments: Edit

After someone is saved (as an example, a sinner is saved in the name of Jesus Christ), a familiars assignment by Satan is to bring the person off the path that God has placed them on. Usually Satan will assign the person with over two familiars to do this, and they can be called Guardian Demons opinionally.

Satanists often use their familiars to do actities involved in witchcraft and magick, and familiars are said to go in the form of animals such as dogs and cats. They are given by Satan to a Satanist or Witch, they of course are said to be treated with respect and care by the owner.
