The Knowby Cabin (often shortened to The Cabin), and the property surrounding it, was located in the state of Michigan, and was owned by Professor Raymond Knowby and his family. Following Raymond's accidental unleashing of the Kandarian Demon in the woods after his discovery of the Necronomicon Ex-Mortis, The Cabin was the central location for a series of supernatural-related events that resulted in the possessions (and eventual deaths) of several people during what was going to be a relaxing weekend trip.
The Knowby Cabin first appeared in the 1981 film The Evil Dead, where it was the main setting.
It first appeared at Halloween Horror Nights as a setting in the Evil Dead haunted house during Halloween Horror Nights 23.
