New Salem is the town where the Circle lives in the book series and located on a little island in the Boston Harbor. It was founded by several witch families who settled there after running away from the Salem Witch Trials.
There are not exactly six witch families forming the Circle in town but an unknown number of families which have some shared blood line throughout their history.
There are no other witch families in town. The other inhabitants are all mortals.
The mortals in New Salem know about witchcraft and the witches in town. They also fear them.
Unlike in Chance Harbor, the previous Circle died in an unsuspected "hurricane", not in a Boatyard Fire. This hurricane was caused by magical means to kill John Black, the previous Circle having discovered his plan to create a perfect Circle to rule over the world.
