Familiars are supernatural entities often associated with witches and magic. They are typically depicted as animals, such as cats, dogs, or birds, that serve as companions and helpers. In folklore, these creatures are believed to assist witches in their magical practices, providing guidance and protection. Historically, familiars were thought to be spirits or demons that took on animal forms. They were believed to enhance a witch's powers and could communicate with them. The concept of familiars has appeared in various cultures and literature, influencing modern portrayals of magic in works like Harry Potter and The Witcher.
