Abiku

Demonic spirits known from the Dahomey folklore of West Africa, these foul elementals live in forested areas, but are known to enter the wombs of women and possess their babies before they are born, killing the children before they reach the age of eleven. After the deaths of their first hosts, the spirits will be reborn into the same families, haunting other children and luring them to similarly-premature deaths. The sound of bells can drive Abiku away from their intended victims.
