The Flat of Alluvial is a gargantuan, efficient nation, ruled by Stono with an even hand, and remarkable for its deadly medical pandemics, keen interest in outer space, and ritual sacrifices. The hard-nosed, humorless, devout population of 18.346 billion Alluvialians are prohibited from doing almost everything except voting, which they do timidly and conservatively.

The medium-sized, corrupt government juggles the competing demands of Law & Order, Defense, and Industry. It meets to discuss matters of state in the capital city of Diluvium. The average income tax rate is 70.9%, and even higher for the wealthy.

The frighteningly efficient Alluvialian economy, worth a remarkable 3,730 trillion Muds 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, fairly diversified black market in Arms Manufacturing, Information Technology, Uranium Mining, and Woodchip Exports. 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 203,347 Muds, and evenly distributed, with the richest citizens earning only 2.7 times as much as the poorest.

Only fully-fledged members of MENSA are allowed to vote, country folk are sent to obligatory boarding schools to learn how to be civilized, no true communist is an unbeliever, and power to the people comes from the barrel of a gun. Crime, especially youth-related, is totally unknown, thanks to a very well-funded police force and progressive social policies in education and welfare. Alluvial's national animal is the Hypnotist, which frolics freely in the nation's many lush forests, and its national religion is Sedimentology.

Alluvial is ranked 18,028^th in the world and 5^th in Medio for Lowest Crime Rates, with 91.38 law-abiding acts per hour.
