The Supreme High Imperium of Terdiatlans is a gargantuan, efficient nation, ruled by Imperator Rhenion Imperios the Merciless with a fair hand, and notable for its keen interest in outer space, rampant corporate plagiarism, and absence of drug laws. The hard-nosed, hard-working, democratic, humorless population of 12.862 billion Terdiatlansians live in a state of perpetual fear, as a complete breakdown of social order has led to the rise of order through biker gangs.

The minute, corrupt, liberal, pro-business, outspoken government, or what there is of one, juggles the competing demands of Industry, Defense, and Administration. It meets to discuss matters of state in the capital city of Therdiopollis Optimum Magna. Income tax is unheard of.

The frighteningly efficient Terdiatlansian economy, worth a remarkable 6,311 trillion Greatest Empyrial Therdiums of Atlantica a year, is driven almost entirely by the private sector, which is broadly diversified and led by the Retail industry, with major contributions from Arms Manufacturing, Gambling, and Information Technology. Average income is an amazing 490,731 Greatest Empyrial Therdiums of Atlantica, but there is a significant disparity between incomes, with the richest 10% of citizens earning 1,585,987 per year while the poor average 114,748, a ratio of 13.8 to 1.

Foreign despots proudly bandstand on Terdiatlansian airwaves, t-shirts displaying a photo of Imperator Rhenion Imperios the Merciless performing the Full-Monty are selling out, the stratosphere is full of "silent but deadly" attacks from Imperator Rhenion Imperios the Merciless's rear echelons, and Terdiatlans isn't what it used to be. Crime, especially youth-related, is so common that it is unusual to encounter someone following the law, perhaps because of the country's complete lack of prisons. Terdiatlans's national animal is the Demon, which is also the nation's favorite main course, and its national religion is The Supreme Imperial Cult.

Terdiatlans is ranked 283,920^th in the world and 1,360^th in Europe for Most Patriotic, with 0.39 flags saluted per person per day.
