Familiars or Imps were demonic creatures in the shape of animals who suckled blood from a witch’s body, to remind her of her devotion and service to the devil. This was considered the symbolic opposite of holy communion.
Witches were often known to name their imps. Wynowe, Jeso, Little Man, Dainty Jack, and Prickears were some of the names given.
These imps were sent out by the witch to do their evil bidding.
