The Unitary Commonwealth Kingdom of Extravania is a mammoth, efficient nation, ruled by Maximus Decimus Meridius with an even hand, and notable for its pith helmet sales, keen interest in outer space, and devotion to social welfare. The compassionate, devout population of 6.057 billion Extravanians are highly moralistic and fiercely conservative, in the sense that they tend to believe most things should be outlawed. People who have good jobs and work quietly at them are lauded; others are viewed with suspicion.

The medium-sized government juggles the competing demands of Administration, Defense, and Education. It meets to discuss matters of state in the capital city of Ninjago City. The average income tax rate is 76.5%, and even higher for the wealthy.

The frighteningly efficient Extravanian economy, worth 859 trillion Extravanian Dollars a year, is fairly diversified and led by the Information Technology industry, with major contributions from Tourism, Arms Manufacturing, and Cheese Exports. State-owned companies are common. Average income is an impressive 141,908 Extravanian Dollars, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Fixing attendance at women's matches is a matter of "when they go low, we go high... funding", a firework a day does not in fact keep the doctor away, the running costs of homeless shelters are so high that it would be cheaper to buy houses for the homeless, and Extravania has been recently classified as an international menace after 'liberating' several nearby territories. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Extravania's national animal is the Phoenix, which soars majestically through the nation's famously clear skies, and its national religion is Christianity.

Extravania is ranked 11,152^nd in the world and 3^rd in The Great Power for Most Developed, scoring 89.96 on the Human Development Index.
