The Aquatic Librarian Knights of Tethys 13 is a gargantuan, efficient nation, ruled by The Grand Council with an even hand, and notable for its zero percent divorce rate, parental licensing program, and irreverence towards religion. The hard-nosed, democratic, humorless population of 31.668 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 8,700 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 274,725 Book-Marks, and distributed extremely evenly, with little difference between the richest and poorest citizens.

History textbook pages are used as impromptu tissues by distraught students, the constant playing of Merry Birthday on Tethysi radio has led to calls for the song to be classified as a crime against humanity, the government regularly publishes lengthy reports on its own excessive recordkeeping, and paper and ink publications are subsidised by the government to keep them in the black. 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 8,657^th in the world and 497^th in Osiris for Lowest Crime Rates, with 103.86 law-abiding acts per hour.
