The Aquatic Librarian Knights of Tethys 13 is a gargantuan, cultured nation, ruled by The Grand Council with an even hand, and notable for its vat-grown people, punitive income tax rates, and stringent health and safety legislation. The hard-nosed, democratic, humorless population of 31.814 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, although Education, Industry, and Administration are also considered important, while Spirituality and International Aid aren't funded at all. 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 8,762 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 169,015^th in the world and 6,704^th in Osiris for Largest Cheese Export Sector, scoring 683.3 on the Mozzarella Productivity Index.
