Curse of the Brotherhood of Seven

The curse of Brotherhoof of Seven removed the essence of the victim from his or her natural body and imprisons the essence into an inanimate object. The victim would suffer from the curse and would not be able to return to his or her body until he or she has killed all seven demons of the brotherhood.

One of the seven demons performed this curse to a demon hunter Sid and trapped him inside a dummy. Sid suffered from the curse for several decades, during which time he tracked and killed all but one of the demons. By the spring of 1997, he managed to track the last demon of the brotherhood in Sunnydale, where a hellmouth is located. With the help of the slayer Buffy and the Scoobies, he was able to kill the demon, moments before it could successfully retrieve a brain to regenerate. As Sid's body has long since decomposed, Sid died once the curse was lifted.
