Demons/Fallen Humans

Demons are a sub-species of the "Circle People." They are mischievous and love to ruin people's reputations. They grant people their "wishes" for a short period of time, and then they drag them down to the "Demon Realm" without telling them that they would. They can also "Possess" people for a short period of time, but it drains their power and takes them a couple years before they can do it again.
