Eigi Einhamr
The Eigi Einhamr are shapeshifters from Norway and Iceland. Its name translates to “not one-skinned” and they are believed to be capable of taking the form of any animal whose skin they wear. Sometimes it is believed that their shapeshifting is rather them sleeping and astrally projecting themselves in the form of various animals. They can switch between human and animal voluntarily and retain all intelligence and morals between their different forms. Some believe their powers of shapeshifting are gifts from the god Odin.
