Derry

Derry, a fictional town located in Maine, was created by horror writer Stephen King as the main setting of the novel IT.

Derry was noted for its many supernatural happenings as well as it was noted to be a conduit or a nexus of paranormal activities and metaphysical events, and it is referenced in many other Stephen King novels.

The town is situated along Interstate 95, to the south of Dexter, the southwest of Old Town, and the west of Bangor and Haven in the southwestern corner of Penobscot County.

History
Before Derry became a town, It, in the form of a ball of fire, came from the Macroverse and went into a slumber, somehow knowing that humanity would arrive. Soon afterwards, people arrived and settled on the land, and It awoke and devoured the children.

It was also held responsible for the mass disappearances of the people on the plantations. It was believed that It allowed Derry to exist just as long as the town provided him with children every twenty-seven years. As a result, every twenty-seven years, It awakens to feed on the town's children.

It also had a great influence over the inhabitants so that they couldn't interfere with its feeding, and in some cases, It would cause most of the residents to indirectly help it. Because of this, murders went unsolved and police would often arrest wrongly-accused people.

This cycle was ultimately stopped when the so-called "Loser Club," the Lucky Seven, seemingly kill It and It destroys almost all of downtown Derry. The town then seems to turn out normal, but it is implied that It might still be alive.
