Flutternutter 

A third world developing country between Iraq and Spain currently embarked on a bloody civil war to break free from its Russian masters. Flutternutter was found in 1569 on the 5th of December by British settlers. Flutternutter has a population 700,000 people and was at its highest point during the 1860's for its abundance of coal. Many flutternutterish people cry for monarchy of Great Britain,cry for democracy and statehood of the U.S.A,and some believe they are fine under Russian rule. The country is currently under leadership of its leader Vladimier Kretrainov but they fight for new leadership with the revolutionary leader who goes by the name Chandelier.
