A Soul Eater feeds from people's spirits.
The Soul Eater sucks the spirit out of a person. It can also suck the spirit out of an object imbued with a spirit.
Seymour was a Soul Eater. Told that it brought luck to its owner, he was tricked by Dyson into sucking an Aitvaras out of its physical form as payback for selling information about his cousin Cassie to Heratio.
A soul eater is a folklore figure in the traditional belief systems of some African peoples, notably the Hausa people of Nigeria and Niger. Belief in soul eaters is related to traditional folk beliefs in witchcraft, zombies, and related phenomena. The soul eater is supposedly able to consume an individual's spirit, causing a wasting disease that can be fatal. The soul eater can take the form of a dog or other animal in pursuit of his or her practice — a belief that connects with the beliefs in werewolves, werecats, selkies, and other were-creatures and human/animal beings found in world folklore. After the soul eater devours a victim's soul, the victim disappears as dust. Some traditional religions, from that of the ancient Egyptians to the Chickasaw, Choctaw, and Natchez, contain figures whose names have been translated into English as "soul eater." These mythological figures, however, are spiritual and not human beings, and so are distinctly different from Hausa and comparable beliefs.
