The World has been divided into several superpowers. Due to the death or slight changes in the life of key scientists and conquerors, the Airship rules the skies. Meanwhile, an earlier but much different evolution of firearms and propulsion changes the face of warfare. The Federated States of America, the Colonial Alliance, the Empire of Mongolia, the United European Commonwealth, the African Confederation and the Republic of Mecca dominated the world. With the buildup and onset of the Great War, the shape of the world was changed forever. Now, the two greatest states in history go to war, darkening the skies with their fleets.
