Peter is taken to another plane, where he confronts a serial killer about to claim his next victim. It's a harrowing encounter that Peter only barely manages to survive. Peter soon realizes that the shadow people are connected to the serial killer, and that he is a member of the Order of Astrum, a group of evil psychics who murdered his parents years ago.
