The Westerly Crab Domain of Teralyon is a colossal, environmentally stunning nation, ruled by Crab Za with an even hand, and renowned for its pith helmet sales, national health service, and punitive income tax rates. The compassionate, humorless population of 6.255 billion Teralyonians are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The medium-sized, corrupt government juggles the competing demands of Education, Administration, and Industry. It meets to discuss matters of state in the capital city of TerraCrab. The average income tax rate is 73.3%, and even higher for the wealthy.

The frighteningly efficient Teralyonian economy, worth a remarkable 1,227 trillion Lyons a year, is fairly diversified and led by the Information Technology industry, with significant contributions from Tourism, Book Publishing, and Furniture Restoration. State-owned companies are common. Average income is an impressive 196,240 Lyons, and evenly distributed, with the richest citizens earning only 2.6 times as much as the poorest.

Public toilets are famed for their rear entries, Eau de Trashcan has become a wildly popular perfume, criminals and college students are taking an interest in the government's new weed-killing program, and social media sites go into shutdown for days at a time to censor user content. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Teralyon's national animal is the Golden Eagle, which soars majestically through the nation's famously clear skies, and its national religion is Crabism.

Teralyon is ranked 1,213^th in the world and 35^th in the West Pacific for Largest Information Technology Sector, scoring 65,742.02 on the Fann-Boi Productivity Index.
