The United Kingdom of Marie Byrd is a colossal, efficient nation, ruled by King Terrance with an even hand, and remarkable for its ritual sacrifices, frequent executions, and devotion to social welfare. The hard-nosed, humorless, devout population of 8.144 billion Marie Byrdians are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The large, corrupt government juggles the competing demands of Defense, Education, and Law & Order. It meets to discuss matters of state in the capital city of Deheubarth. The average income tax rate is 88.7%, and even higher for the wealthy.

The frighteningly efficient Marie Byrdian economy, worth a remarkable 1,656 trillion Grant Island Pounds a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. However, for those in the know, there is an enormous, deeply entrenched black market in Arms Manufacturing, Information Technology, Book Publishing, and Uranium Mining. The private sector mostly consists of enterprising ten-year-olds selling lemonade on the sidewalk, but the government is looking at stamping this out. Average income is an amazing 203,416 Grant Island Pounds, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Psychiatrists bizarrely accompany King Terrance to meetings with foreign heads of state, the Communist Party claims that selling things for profit isn't necessarily capitalism, captains must wait until all rats are safe before jumping ship, and helping grandma with her Misgendering 101 homework is a national rite of passage. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Marie Byrd's national animal is the Penguin, which frolics freely in the nation's sparkling oceans, and its national religion is Church of Marie Byrd.

Marie Byrd is ranked 250,598^th in the world and 330^th in Thaecia for Fattest Citizens, with 7.07 Obesity Rate.
