Bang later discovers that the discomfort is a failed attempt at mind control by a demon trapped beneath the mountain at Demonhead's northern end. The demon failed to control Bang, but manages to control Bang's ally, Michael. The demon sets up a plot through Michael to entice Bang with treasure requiring the use of a Magic Stone. The Magic Stone ends up being the key to freeing the demon from its imprisonment. After Bang fails to defeat the demon, it seeks out and kills Tom Guycot and steals his medallion. Bang learns from the hermit that the demon can only be destroyed with the Sword of Apollo.
