causing harm. The only constants are that they take the form of ritually mutilated people with varying degrees of human characteristics, and that they can only reach Earth's reality when summoned through a schism in time and space, which is opened and closed using a puzzle box known as the Lament Configuration or, as described in the original story, the Lemarchand Configuration. Concept and design After being disappointed with the way his material had been treated by producers in Underworld, Barker wrote The Hellbound Heart as his first step in directing a film by himself. The book describes a group of sadomasochistic entities who live in an extra-dimensional realm, where they perform "experiments" on humans in extreme sexual experiences. Although antagonist Frank Cotton believes they will take the form of beautiful women, they appear instead as monsters: Author David McWilliam notes that the Cenobites are described in more explicitly sexual terms in the book compared with their depictions in the film adaptations. The four Cenobites described in the book each present unique mutilations and modifications: one Cenobite has stitches through its eyelids and a system of chains with bells hooked into various parts of its body; another has a grid tattooed to its head with jeweled pins driven into its skull at the intersections; the eyes of yet another are swollen shut and its mouth heavily disfigured; finally, a female Cenobite has undergone elaborate scarification to her pubis. The fifth, lead Cenobite, referred to as "The Engineer", appears briefly in the book's climax as an average human being whose body glows with intense light when he travels between realms. After securing funding for a motion picture adaptation in early 1986, Barker and his producer Chris Figg assembled a team to design the cenobites. Among the team was Bob Keen and Geoff Portass at Image Animation and Jane Wildgoose, a costume designer who was requested to make a series of costumes for four or five "super-butchers" while refining the scarification designs with Image Animation. Barker drew inspiration for the Cenobite designs from punk fashion, Catholicism, and by the visits he took to BDSM clubs in New York City and Amsterdam. Each of the four primary Cenobites from The Hellbound Heart were featured in the film, with appearances based upon their descriptions in the book. The first Cenobite became Butterball, the second Pinhead, the third Chatterer, and the fourth The Female. The
