The Salem Witchcraft Trials were a dark time in the early history of the United States. The deep feelings of paranoia, fear, and treachery were strong enough that it invested itself upon The Strange. Without anyone to foster it, the recursion grew. Today the recursion consists of the town of Salem, as well as some of the surrounding wilderness. By day, the citizens of the town go about their business, ever wary of Witches that may be lurking nearby. But at night, all citizens lock themselves up within their houses, for fear of things that prowl the dark. The witches themselves are real, and have dark monstrosities in their employ. The majority of witches are awakened, and seek to find the means to either leave the recursion, or to bring in artifacts powerful enough to grant them complete dominion over it.
Witches-on entering the recursion, a recursors choice of foci determines their race. If the foci only relies on standard physics, they come into the recursion as a human. However if their foci requires Magic, they are branded a Witch upon entering. Somewhere on their body will be a strange birthmark, signifying their difference according to the beliefs of the townsfolk. However, just because a recursor is not a witch will not protect them from being accused of being a witch.
