The Geolemon was an artifact created by the Amidonians to test their theories on military psychology. The Geolemon was sent to Geographia in a fake meteorite where it started The Great Lemon War. The Geolemon is a lemon shaped object which gives a person supernatural powers, but also makes him or her evil. This led to Geographian countries to argue about what they should do about it, thus starting the Great Lemon War. The Geolemon was presumably destroyed after the Great Lemon War.
