The Imperial Dominion of Arithei is a gargantuan, efficient nation, ruled by Lord Lanair with a fair hand, and notable for its infamous sell-swords, daily referendums, and smutty television. The hard-nosed, hard-working, democratic, cheerful population of 49.277 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, with Environment, Industry, and Administration also on the agenda, 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 86.1%, and even higher for the wealthy.

The frighteningly efficient Aritheian economy, worth an astonishing 21,763 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 441,664 Drachmas, and evenly distributed, with the richest citizens earning only 2.1 times as much as the poorest.

Prenuptial contracts have replaced diamond rings in marriage proposals, claiming to have performed the Heimlich Maneuver is a popular defense for assault charges, political detractors refer to Lord Lanair as 'that Bigtopian puppet', and children often explain to their parents that the Mega Ultimate Sword Fist was worth the thousand-Drachma charge on their phone bill. Crime is totally unknown. Arithei's national animal is the Lynx, which is also the nation's favorite main course.

Arithei is ranked 21,212^th in the world and 75^th in NationStates for Largest Gambling Industry, scoring 6,924.15 on the Kelly Criterion Productivity Index.
