The United Socialist States of Eridium is a colossal, safe nation, ruled by Soren Vylkas with an even hand, and notable for its ban on automobiles, hatred of cheese, and restrictive gun laws. The compassionate population of 3.958 billion Eridians are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The enormous government juggles the competing demands of Education, Administration, and Environment. It meets to discuss matters of state in the capital city of Vilkas. The average income tax rate is 95.1%.

The all-consuming Eridian economy, worth 430 trillion Credits a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is highly specialized, is mostly made up of the Information Technology industry, with significant contributions from Tourism and Book Publishing. Average income is an impressive 108,710 Credits, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Explicit slash fiction is repackaged for kindergarten kids as stories about friends cuddling friends, a positive GPA is all it takes to get an elite education, the threat of economic apocalypse brings out the best in people, and every spring railroad foundations erode to reveal human remains. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Eridium's national animal is the Wolf, which frolics freely in the nation's many lush forests.

Eridium is ranked 264,958^th in the world and 83^rd in The Hole To Hide In for Largest Trout Fishing Sector, scoring -4.9 on the Nemo Depletion Efficiency Index.
