The Imperial Dominion of Arithei is a gargantuan, socially progressive nation, ruled by Lord Lanair with an even hand, and remarkable for its pith helmet sales, restrictive gun laws, and stringent health and safety legislation. The hard-nosed, democratic, cheerful population of 44.215 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 aren't funded at all. It meets to discuss matters of state in the capital city of Alqualondë. The average income tax rate is 86.6%, and even higher for the wealthy.

The frighteningly efficient Aritheian economy, worth an astonishing 18,374 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 415,560 Drachmas, and distributed extremely evenly, with little difference between the richest and poorest citizens.

The nation's laws on image rights are amongst the strictest in the world, the national defense strategy is a little floppy, the nation threatens sanctions on islands only visible at low tide, and intoxicated AI mobile platforms are sometimes seen crashing through windows instead of being crashed by them. Crime is totally unknown. Arithei's national animal is the Lynx, which frolics freely in the nation's many lush forests.

Arithei is ranked 5,820^th in the world and 94^th in NationStates for Largest Cheese Export Sector, scoring 6,719.75 on the Mozzarella Productivity Index.
