The Blessed Transmatriarchy of Riveraland is a colossal, cultured nation, ruled by Queen Elena IV with an even hand, and renowned for its museums and concert halls, keen interest in outer space, and punitive income tax rates. The compassionate population of 6.105 billion Riverans enjoy extensive civil rights and enjoy a level of social equality free from the usual accompanying government corruption.

The government — a sprawling, bureaucracy-choked, liberal, socially-minded morass — juggles the competing demands of Education, Healthcare, and Administration. It meets to discuss matters of state in the capital city of Lesbos. The average income tax rate is 92.1%, and even higher for the wealthy.

The very strong Riveran economy, worth 507 trillion petals a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is extremely specialized, is mostly made up of the Trout Farming industry, with major contributions from Information Technology. Average income is 83,170 petals, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

Signs at the border tell international drivers where they can put their cars, fixing attendance at women's matches is a matter of "when they go low, we go high... funding", internet searches for the inventor of the three-wheeled steam-powered Riveran weed picker are way up, and the fattest folk in Riveraland look to be the happiest ones. Crime is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Riveraland's national animal is the cat, which frolics freely in the nation's many lush forests, and its national religion is Trans-Sophianism.

Riveraland is ranked 10,405^th in the world and 334^th in The East Pacific for Most Advanced Public Education, scoring 10,615.85 on the Edu-tellignce® Test Score.
