The United Socialist States of Eridium is a colossal, efficient nation, ruled by Soren Vylkas with an even hand, and renowned for its complete lack of prisons, ban on automobiles, and punitive income tax rates. The compassionate population of 3.821 billion Eridians are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The government — a sprawling, bureaucracy-choked, socially-minded morass — 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 95.0%.

The all-consuming Eridian economy, worth 406 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. Average income is an impressive 106,462 Credits, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Metal detectors have been banned after a bottle cap caused a riot at the beach, legal contracts aren't worth the paper they're written on, ad-blocking has been nationalised, and compliance officers smash the kneecaps of unethical bureaucrats. 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 2,573^rd in the world and 4^th in The Hole To Hide In for Most Eco-Friendly Governments, scoring 11,030.06 on the Dolphin Recycling Awareness Index.
