The Socialist Dominion of Tethysius is a gargantuan, efficient nation, ruled by Raptah Osiruseth with an iron fist, and remarkable for its parental licensing program, anti-smoking policies, and stringent health and safety legislation. The hard-nosed, cynical, humorless population of 34.563 billion Tethysians are ruled by a mostly-benevolent dictator, who grants the populace the freedom to live their own lives but watches carefully for anyone to slip up.

The medium-sized, corrupt, well-organized government prioritizes Defense, with Law & Order, Administration, 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 42.7%.

The frighteningly efficient Tethysian economy, worth a remarkable 6,145 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 177,797 Atlas, and evenly distributed, with the richest citizens earning only 3.2 times as much as the poorest.

Suburban backyards are seized by the government and turned into national parks, there's nothing more gay than bleeding for your nation, urban entrepreneurs are busy introducing cockroaches into restaurant kitchens, and many politicians are in rehab for minor drug offenses. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Tethysius's national animal is the Ghidorah, which is also the nation's favorite main course, and its national religion is non exstat.

Tethysius is ranked 3,714^th in the world and 1^st in Aviatorino for Largest Populations, with 34.6 billion capita.
