Shifters are fictional beings often found in fantasy literature and folklore. They possess the unique ability to transform their physical form into that of another creature, typically an animal. This transformation can be voluntary or involuntary, depending on the specific lore surrounding the shifter. In many stories, shifters are depicted as having a deep connection to nature and the animal world. They may use their abilities for various purposes, such as protection, exploration, or even deception. Common examples of shifters include werewolves and skinwalkers, each with their own cultural significance and rules governing their transformations.
