Cybil Bennett is a strong-willed female police officer from Brahms, a town neighboring Silent Hill. She is sent to Silent Hill to investigate her precinct's lack of communication with the Silent Hill Police and is unwittingly drawn into its strange world. Unlike the other human characters, Cybil is a skeptic and has difficulty accepting the paranormal activity in town. She quickly befriends Harry Mason and attempts to help him to find his daughter, Cheryl.
The Play Novel reveals more of Cybil's backstory. When Cybil was a little girl, her parents were murdered by an unidentified man. Cybil, who was hiding in a closet at the time, looked through the closet's crack and witnessed her parents being shot in the head. This incident largely impacted her future, which was the main influence on her becoming a policewoman.
