The Union State of Mariinsk is a massive, environmentally stunning nation, ruled by Petra Bedernjak with an even hand, and remarkable for its keen interest in outer space, frequent executions, and stringent health and safety legislation. The quiet, industrious population of 1.691 billion Mariinskians have some civil rights, but not too many, enjoy the freedom to spend their money however they like, to a point, and take part in free and open elections, although not too often.

The medium-sized government juggles the competing demands of Administration, Law & Order, and Education. It meets to discuss matters of state in the capital city of Muromii. The average income tax rate is 68.0%, and even higher for the wealthy.

The frighteningly efficient Mariinskian economy, worth 237 trillion Rubles a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is fairly diversified, is led by the Tourism industry, with major contributions from Information Technology, Book Publishing, and Arms Manufacturing. Average income is an impressive 140,353 Rubles, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Libraries are refusing to stock A Midsummer Night's Dream because it has an ass in it, tradesmen will knock 10% off their fees if customers pay cash, Coco the Clown has been elected to the nation's parliament, and the military is slashing spending on conventional arms and diverting it to spending on prosthetic arms. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Mariinsk's national animal is the red deer, which frolics freely in the nation's many lush forests, and its national religion is the United National Church of Mariinsk.

Mariinsk is ranked 23,278^th in the world and 585^th in the Rejected Realms for Most Scientifically Advanced, scoring 257.09 on the Kurzweil Singularity Index.
