The Aquatic Librarian Knights of Tethys 13 is a gargantuan, socially progressive nation, ruled by The Grand Council with a fair hand, and renowned for its vat-grown people, complete lack of prisons, and national health service. The hard-nosed, democratic, humorless population of 27.606 billion Tethysi enjoy a sensible mix of personal and economic freedoms, while the political process is open and the people's right to vote held sacrosanct.

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 98.2%.

The frighteningly efficient Tethysi economy, worth a remarkable 7,381 trillion Book-Marks a year, is quite specialized and led by the Information Technology industry, with major contributions from Arms Manufacturing and Book Publishing. State-owned companies are common. Average income is an amazing 267,392 Book-Marks, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Graffiti graces every city's streets, internet ads promising "hot singles in your area" are even less accurate than they used to be, escargots have lost their charm ever since they started to be called 'cooked land snails', and friendly fire incidents usually result in severe burns. Crime, especially youth-related, 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 173,102^nd in the world and 4,852^nd in Osiris for Most Extreme, scoring 14.85 on the Paul-Nader Subjective Decentrality Index.
