Azazel

A small demon which enjoys making those who trust one each other turn on one another. Originally a fairy, it was reprimanded for disclosing knowledge to humans, and was expelled, turning it into a demon. It holds a grudge of being treated badly despite doing good, and is now doing its utmost in planting the emotion of betrayal within humans holding trust. They are a sad existence, but compassion is futile as they will even try to use that to their advantage.
