The Kingdom of Under Atlantis is a gargantuan, orderly nation, ruled by Neptune with an iron fist, and remarkable for its ritual sacrifices, keen interest in outer space, and devotion to social welfare. The hard-nosed, hard-working, cynical, humorless, devout population of 17.868 billion Drowned Sailors are kept under strict control by the oppressive government, which measures its success by the nation's GDP and refers to individual citizens as "human resources."

The enormous, corrupt, well-organized government juggles the competing demands of Administration, Industry, and Law & Order. It meets to discuss matters of state in the capital city of Atlantis. The average income tax rate is 95.0%.

The frighteningly efficient Under Atlantisian economy, worth a remarkable 4,210 trillion Airs a year, is quite specialized and mostly comprised of black market activity, especially in Retail, Basket Weaving, Uranium Mining, and Information Technology. Average income is an amazing 235,635 Airs, and evenly distributed, with the richest citizens earning only 2.5 times as much as the poorest.

Contestants on Under Atlantis's Got Talent are screened by the government to make sure that they actually have talent, government officials go door-to-door educating about the dangers of pseudoscience, arthritic citizens seem underrepresented at royal meet-and-greets, and baby dolls thrown in the trash are a leading cause of panic attacks. Crime, especially youth-related, is totally unknown, thanks to the all-pervasive police force and progressive social policies in education and welfare. Under Atlantis's national animal is the Mermaid, which is also the nation's favorite main course.

Under Atlantis is ranked 22,142^nd in the world and 2^nd in Atlantic for Most Patriotic, with 45.07 flags saluted per person per day.
