In the United States of North America, "the Union" refers to the territory that the Union occupied during the American Civil War west of the Mississippi River, or what is typically referred to as just "the North." Specifically, the Union is comprised of Wisconsin, Illinois, Indiana, Ohio, Michigan, Maryland, West Virginia, Delaware, Pennsylvania, New Jersey, New York, Massachusetts, Vermont, Rhode Island, Connecticut, New Hampshire, and Maine. The American capital, Washington D.C., is also located in this region. Much of the American Revolutionary Wars were fought in this region.

TIMELINE AND SETTING NOTES:
- there was no 9/11 attack in this world; as such, the Twin Towers of the World Trade Center still stand in New York City
