Jerusalem's Lot (Stephen King)
Jerusalem's Lot, Maine (often shortened to 'Salem's Lot or just the Lot) is a fictional town and a part of writer Stephen King's fictional Maine topography. 'Salem's Lot has served as the setting for a number of his novels, novellas, and short stories. 'Salem's Lot first appeared in King's 1975 novel "'Salem's Lot", and has reappeared as late as his 2013 novel "Doctor Sleep" (see list below). The town is described as being located in Cumberland County, between (or including parts of) the towns of Falmouth, Windham, and Cumberland, near the southern part of the state about ten miles north of Portland. A map on King's official website, though, places 'Salem's Lot considerably further north, approximately in Northwest Piscataquis.
Salem's Seven
Salem's Seven originated in New Salem, Colorado, a hidden town in an unsettled part of the Rocky Mountains populated entirely by magic users who mostly lived in fear and loathing of normal humanity due to the persecution that was imposed on them during the Salem witch trials. All of Salem's Seven were fathered among different women by Nicholas Scratch. Scratch's own mother Agatha Harkness was the most powerful of the town's inhabitants, but she chose to leave the village and live among humanity. In time, she became the governess for Franklin Richards (son of Invisible Woman and Mister Fantastic of the Fantastic Four). Scratch had Salem's Seven abduct Agatha for purportedly betraying the New Salem community. They also brought back Franklin with them to give to Scratch as a new host-body, which forced the Fantastic Four to pursue. Although initially overcome and imprisoned, the Four defeated their captors, banished Scratch from this dimension, and saved Harkness. When Salem's Seven much later tried to avenge themselves on Harkness, she removed their ability to change forms.
