The Socialist Dominion of Tethysius is a gargantuan, efficient nation, ruled by Raptah Osiruseth with an iron fist, and notable for its ban on automobiles, keen interest in outer space, and complete absence of social welfare. The hard-nosed, cynical, humorless population of 22.899 billion Tethysians 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 medium-sized, corrupt, well-organized government prioritizes Defense, with Law & Order, Environment, and Education also on the agenda, while Spirituality and Welfare are ignored. It meets to discuss matters of state in the capital city of Orthosia. The average income tax rate is 50.0%, and even higher for the wealthy.

The all-consuming Tethysian economy, worth a remarkable 3,368 trillion Atlas a year, is highly specialized and mostly comprised of black market activity, especially in Arms Manufacturing, Retail, Information Technology, and Cheese Exports. State-owned companies are reasonably common. Average income is an impressive 147,101 Atlas, and distributed extremely evenly, with little difference between the richest and poorest citizens.

It's always rabbit season, new homeowners go furniture hunting with crowbars, shops were recently ransacked as cigarettes returned to the shelves, and the military invades any neighboring nation with the gall to criticize its policies. Crime, especially youth-related, is totally unknown, thanks to a very well-funded police force. Tethysius's national animal is the Ghidorah, which is also the nation's favorite main course, and its national religion is Non Existent.

Tethysius is ranked 375^th in the world and 1^st in Venus Project for Most Secular, with 99.21 Atheism Rate.
