Any Alliance can at a given time govern 3 States. Any other Alliance can invade this State to take it away. Once an Invasion is made, war starts in 10 Minutes. The rules of World War are a bit different from normal wars. World wars have a weighted point system: Win can give max. 10 points and kill can give max. 20 points, both based on the level difference between the two opponents. If a war lasts 1 hour and if the challenger is not able to defeat the Alliance, the state stays with the current Alliance. In case an Alliance is governing multiple States, it will have to defend those States from multiple Alliance. The fighting over States varies with the State where the fighting is taking place. Each State has its own war rules.
