Ohio is a location in the United Republic of North America. One of the cites in Ohio is Cleveland.[1][2]


Ohio became 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 Cleveland, hoping the Covenant would spare it, as his brother Ruwan lived there.[3]

It also had a known UNSC relief camp in Akron, Ohio for refugees after the battle.[3]
