The Imperial Dominion of Arithei is a gargantuan, socially progressive nation, ruled by Lord Lanair with an even hand, and notable for its complete lack of prisons, pith helmet sales, and restrictive gun laws. The hard-nosed, democratic, cheerful population of 44.164 billion Arithites enjoy extensive civil freedoms, particularly in social issues, while business tends to be more regulated.

The relatively small, liberal government is primarily concerned with Education, although Environment, Industry, and Healthcare are also considered important, while Spirituality and Social Policy are ignored. It meets to discuss matters of state in the capital city of Alqualondë. The average income tax rate is 85.8%, and even higher for the wealthy.

The frighteningly efficient Aritheian economy, worth an astonishing 18,369 trillion Drachmas a year, is led by the Information Technology industry, with major contributions from Book Publishing, Tourism, and Retail. State-owned companies are common. Average income is an amazing 415,931 Drachmas, and evenly distributed, with the richest citizens earning only 2.7 times as much as the poorest.

It's illegal to be caught on tape, the government finds the idea of having an army to be rather distasteful, the alarmingly racist TV show 'Bigtopians Say the Darndest Things' is a hit, and saying "don't do anything that Lord Lanair wouldn't do" doesn't exclude a great deal. Crime is totally unknown. Arithei's national animal is the Lynx, which frolics freely in the nation's many lush forests.

Arithei is ranked 193^rd in the world and 2^nd in NationStates for Highest Food Quality, scoring 534.67 on the Meeshlin-Starr Index.
