Adze
Adze is a vampire from Ewe mythology. In the wild, the Adze takes the form of a firefly, allowing it to travel through keyholes and cracks at night. Once inside a home, it drinks the blood of sleeping victims, causing sickness and death. If captured, the Adze transforms into human shape, revealing either a possessed witch or a grotesque diminutive humanoid. People possessed by an Adze are viewed as witches (abasom). The legend likely originated as an explanation for mosquito-borne illnesses like malaria
