The Aquatic Librarian Knights of Tethys 13 is a gargantuan, socially progressive nation, ruled by The Grand Council with an even hand, and remarkable for its avant-garde cinema, compulsory vegetarianism, and sprawling nuclear power plants. The hard-nosed, democratic, humorless population of 31.734 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 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 8,718 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 274,736 Book-Marks, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Prankster scientists legally change their names to silly pseudonyms before major discoveries, military funding has been stripped back, citizens select which government department gets their income tax Book-Marks each year, and stockbrokers dream of getting rich by writing textbooks. 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 3,715^th in the world and 148^th in Osiris for Most Advanced Public Education, scoring 16,982.56 on the Edu-tellignce® Test Score.
