Chicago is the third most populous city in the United States. The city has approximately 2.7 million residents. Its metropolitan area, sometimes called "Chicagoland", is the third-largest in the United States, after New York City and Los Angeles, with an estimated 9.8 million people. Chicago is the county seat of Cook County, though a small portion of the city limits also extend into DuPage County.

Damien - Omen IIEdit

Davidson Military Academy and the Thorn Museum, as well as the heart of Thorn Industries, are located in Chicago. Richard, Ann and Mark Thorn also live in Chicago, as does Damien following the deaths of the latter's adoptive parents. When Mark is killed by Damien and Richard discovers Damien's identity as the Antichrist, Damien kills Ann and Richard (destroying the Thorn Museum in the process) and becomes heir to Thorn Industries.
