One type of narrative offered by the Westworld park are suspensful storylines or adventures that include horror elements. The horror elements tend to be overt, and sometimes even deliberately over-the-top. Collectivelly, these storylines are horror narratives.
Known horror narratives
There isn't just a single horror narrative. From information provided during the first season by park employees and events in the park, it's clear Westworld had several different horror narratives in the past, and is still currently operating at least one or two horror storylines/missions.
|“||I shall have such revenges on you... both. The things I will do, what they are, yet I know not. But they will be the terrors of the earth. You don't know where you are, do you? You're in a prison of your own sins.||”|
An old horror narrative from the park's previous decades, co-developed by Dr. Ford himself. It included cannibalism and a well-educated but sinister character, known as "The Professor", who liked to quote Shakespeare's plays. The host who played the Professor would go on to portray Dolores' father, Peter Abernathy.
After a reveries update, Peter finds a modern day photograph misplaced in the park several decades ago. Deeply confused about the contents of the photo (depicting a modern city skyline and a woman in modern clothing), he begins to increasingly suffer from abnormal glitching. As a consequence of his malfunctions, he starts to haphazardly recall bits and pieces of the characters he used to play in the past. At one point, he recalls his lines and mannerisms as the Professor, and begins to verbally threaten Ford and his colleague Bernard Lowe, quoting Shakespeare's plays, in-character.
Though the staff of the Behavior division are briefly terrified, Ford calmly explains the origins of Peter's bizarre behaviour and lines, and briefly talks about the narrative, with a slight hint of nostalgia.
|“||He liked to quote Shakespeare, John Donne, Gertrude Stein. I admit the last one is a bit of an anachronism, but I couldn't resist."||”|
–Dr. Ford explaining the literary references made by Peter as the "Professor", including some anachronistic quotes
Masked cult narrative
During the present day of the Westworld park, there appears to be some form of horror narrative involving ambushes on guests (and their host guides) by groups of masked and armed cultists. Members of the cult wear frightening masks with an animal motif, often that of horned animals. They tend to attack unsuspecting groups of people at night time, taking them by surprise out in the wilderness areas of Westworld.
There are also non-masked members of this cult, such as the current iteration of Angela. She seems to portray the role of a cult member or accomplice, who poses as a victim of the cultists, only to lure unsuspecting travellers into an ambush.
Throughout the first season, there are some hints that the existence of this narrative might be loosely tied to that of the Wyatt narrative. Wyatt's followers also include masked, armed men (though with simpler masks of black cloth) and Wyatt is often spoken of by host characters as an extremely dangerous individual. Wyatt is described as a pillager and tyrant, and according to the hosts that "have heard" legends and rumours about the character, he (or she) believes themselves to be a living deity.
|“||This storyline will make Hieronymus Bosch look like he was doodling kittens ! I have vivisection, self-cannibalism, a special little something I call the "whoroborus." (chuckles) Now, I don't want to appear immodest, but this is the apex of what the park could provide... Horror... Romance... Titilation...||”|
–Lee Sizemore confidently presenting his narrative pitch to an unconvinced Ford and audience
Dr. Ford dismisses Sizemore's narrative as filled with pointless "cheap thrills". He then lectures Sizemore on his misunderstanding of what guests expect from the adventures provided by the park, in terms of personal self-discovery.
