A map of the United States of America. Ohio is the red state.
Ohio is a state in the United Republic of North America. It was also the 17th state in the United States of America. One of the cites in Ohio is Cleveland, the site of the Battle of Cleveland. During the Battle of Earth, Colonel James Ackerson claimed that an imaginary artifact known as the Key of Osanalan was located under the city, hoping the Covenant would spare it, as his brother Ruwan lived there. It also had a known UNSC relief camp in Akron, Ohio for refugees after the battle.[1]
