The Fiefdom of Marquess of Marchmain is a mammoth, genial nation, ruled by Lord Marchmain with an even hand, and remarkable for its free-roaming dinosaurs, complete lack of prisons, and sprawling nuclear power plants. The compassionate population of 6.707 billion Subjects are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The enormous, socially-minded government juggles the competing demands of Education, Administration, and Environment. It meets to discuss matters of state in the capital city of New Marchmain. The average income tax rate is 82.8%, and even higher for the wealthy.

The very strong a Subject economy, worth 502 trillion Pounds a year, is quite specialized and mostly made up of the Tourism industry, with significant contributions from Book Publishing. State-owned companies are common. Average income is 74,980 Pounds, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

The tax agency is feared more than serial killers and terrorists, planes can be grounded for months simply because an inspector "didn't like the color", internet ads promising "hot singles in your area" are even less accurate than they used to be, and lines of trenches demarcate the nation's borders. Crime, especially youth-related, is totally unknown, thanks to a very well-funded police force and progressive social policies in education and welfare. Marquess of Marchmain's national animal is the Cardinal, which frolics freely in the nation's many lush forests, and its national religion is Church of Marchmain.

Marquess of Marchmain is ranked 9,376^th in the world and 7^th in Empire of Great Britain for Most Eco-Friendly Governments, scoring 5,783.61 on the Dolphin Recycling Awareness Index.
