The Aquatic Librarian Knights of Tethys 13 is a gargantuan, environmentally stunning nation, ruled by The Grand Council with an even hand, and remarkable for its vat-grown people, anti-smoking policies, and zero percent divorce rate. The hard-nosed, democratic, humorless population of 31.82 billion Tethysi enjoy extensive civil freedoms, particularly in social issues, while business tends to be more regulated.

The medium-sized government is primarily concerned with Defense, with Education, Industry, and Administration also on the agenda, while Spirituality and International Aid are ignored. It meets to discuss matters of state in the capital city of Atr'Lyanteth'Ys. The average income tax rate is 98.1%.

The frighteningly efficient Tethysi economy, worth a remarkable 8,764 trillion Book-Marks a year, is quite specialized and led by the Information Technology industry, with major contributions from Book Publishing and Arms Manufacturing. State-owned companies are common. Average income is an amazing 275,424 Book-Marks, and distributed extremely evenly, with little difference between the richest and poorest citizens.

The "Underwear of Women in Power" issue of The Atr'Lyanteth'Ys Times is sold out, scientific journals publish third-graders' school essays, holidaymakers sleep curled up on the floor as hotel beds are replaced with oversized bookcases, and conductors wield diamond-encrusted batons to fit in with their freshly gilded surroundings. Crime is totally unknown. Tethys 13's national animal is the Feathered Eel, which frolics freely in the nation's sparkling oceans, and its national religion is Necronomiconianism.

Tethys 13 is ranked 866^th in the world and 24^th in Osiris for Most Scientifically Advanced, scoring 1,029.96 on the Kurzweil Singularity Index.
