The Dwayyo (or Dewayo) is a human bound within an animal’s body. It is believed that the transformation takes place consensually. Early settlers have recounted how viscous and incredible these encounters could be. Records from the mid-late 1900's describe a creature that is similar to a bipedal wolf, aggressive towards humans, and of a predatory nature.

Once human, the Dewayo is a type of Dogman—a category of organism that transforms between wolf and man (or a halfway state) through magical means. For the Dewayo, however, the transformation is permanent and comes with a cost: they must hunt down and feed upon Snallygasters for the rest of their life, or perish. Those who choose to become a Dewayo give up most of their humanity and the ability to dwell beyond the Maryland border, but gain everlasting life as long as they adhere to Dewayo restrictions and requirements.
