The United Species of The Eridani Imperium is a gargantuan, cultured nation, ruled by Imperātor Aenar Westfall with an even hand, and renowned for its keen interest in outer space, ubiquitous missile silos, and absence of drug laws. The hard-nosed, devout population of 14.446 billion Eridani have some civil rights, but not too many, enjoy the freedom to spend their money however they like, to a point, and take part in free and open elections, although not too often.

The large, corrupt government juggles the competing demands of Defense, Education, and Law & Order. It meets to discuss matters of state in the capital city of Ebonheart. The average income tax rate is 98.4%.

The frighteningly efficient Eridani economy, worth a remarkable 4,755 trillion Septims a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. However, for those in the know, there is an enormous, deeply entrenched, fairly diversified black market in Arms Manufacturing, Information Technology, Book Publishing, and Tourism. The private sector mostly consists of enterprising ten-year-olds selling lemonade on the sidewalk, but the government is looking at stamping this out. Average income is an amazing 329,205 Septims, and evenly distributed, with the richest citizens earning only 3.2 times as much as the poorest.

All major public areas are watched by police surveillance cameras, court cases mostly involve lawyers shouting questions at witnesses giving silent shrugs, this year's hottest fashion trend is the Lese Majeste collection, and the serf suggestion box would work better if more serfs were literate. Crime is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. The Eridani Imperium's national animal is the Griffin, which soars majestically through the nation's famously clear skies, and its national religion is The Et'Ada.

The Eridani Imperium is ranked 3,211^th in the world and 125^th in Balder for Most Beautiful Environments, with 2,939.08 pounds of wildlife per square mile.
