The Commonwealth of Erosi is a colossal, socially progressive nation, ruled by Thessia Caddel with an even hand, and remarkable for its parental licensing program, sprawling nuclear power plants, and devotion to social welfare. The compassionate population of 7.642 billion Erosians are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The large government juggles the competing demands of Administration, Education, and Healthcare. It meets to discuss matters of state in the capital city of Riosa. The average income tax rate is 97.7%.

The frighteningly efficient Erosian economy, worth a remarkable 1,625 trillion Chronocredits a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector is led by the Information Technology industry, with major contributions from Tourism, Book Publishing, and Beef-Based Agriculture. Average income is an amazing 212,666 Chronocredits, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Bowling teams spend more time looking at their phones than the pins, the new 'Who Wants To Be A Politician' election debate auditions are more popular than the debates themselves, heart attack victims are thrown onto the rails, and crowded passenger trains are near-silent save for the soft tap of fingers on touchscreens. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Erosi's national animal is the Platypus, which is also the nation's favorite main course, and its national religion is Heathenry.

Erosi is ranked 6,170^th in the world and 315^th in Balder for Most Scientifically Advanced, scoring 511.23 on the Kurzweil Singularity Index.
