The Imperial Dominion of Arithei is a gargantuan, socially progressive nation, ruled by Lord Lanair with a fair hand, and notable for its pith helmet sales, free-roaming dinosaurs, and irreverence towards religion. The hard-nosed, hard-working, democratic, cheerful population of 49.48 billion Arithites hold their civil and political rights very dear, although the wealthy and those in business tend to be viewed with suspicion.

The relatively small, liberal, outspoken government is primarily concerned with Education, although Industry, Environment, and Administration are also considered important, while Spirituality and Social Policy receive no funds. It meets to discuss matters of state in the capital city of Alqualondë. The average income tax rate is 87.0%, and even higher for the wealthy.

The frighteningly efficient Aritheian economy, worth an astonishing 21,937 trillion Drachmas a year, is led by the Information Technology industry, with major contributions from Book Publishing, Tourism, and Retail. Average income is an amazing 443,361 Drachmas, and evenly distributed, with the richest citizens earning only 2.4 times as much as the poorest.

Ride-sharing often involves some passengers sitting on the roof rack, expensive lawyers are hired to defend citizens in court for public urination charges against their pets, a long-distance hike gets students geared up for a long day at school, and compliance officers smash the kneecaps of unethical bureaucrats. Crime is totally unknown. Arithei's national animal is the Lynx, which is also the nation's favorite main course.

Arithei is ranked 501^st in the world and 23^rd in NationStates for Rudest Citizens, with 606.27 insults per minute.
