The Unified Planet of Selios is a mammoth, socially progressive nation, ruled by Worldmind Selios with a fair hand, and renowned for its ubiquitous missile silos, multi-spousal wedding ceremonies, and soft-spoken computers. The compassionate, democratic, cheerful, devout population of 5.919 billion Sebolds are free to do what they want with their own bodies, and vote for whomever they like in elections; if they go into business, however, they are regulated to within an inch of their lives.

The tiny, liberal, socially-minded, outspoken government juggles the competing demands of Education, Industry, and Healthcare. It meets to discuss matters of state in the capital city of Illumina. The average income tax rate is 3.5%, but much higher for the wealthy.

The frighteningly efficient Selion economy, worth a remarkable 1,558 trillion Manas a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is broadly diversified, is led by the Information Technology industry, with major contributions from Tourism, Book Publishing, and Beef-Based Agriculture. Average income is an amazing 263,252 Manas, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

Insomniacs read government expense reports to fall asleep, sports fans complain that cricket tests now last an unbearable ten days, dozens of viewers go online to hear whether a comma has been added to Clause 5 in Subsection B of Law 58375, and frequent flyers are chiseled into statues. Crime is totally unknown. Selios's national animal is the Pseudodragon, which soars majestically through the nation's famously clear skies, and its national religion is Orism.

Selios is ranked 4,494^th in the world and 5^th in The Galactics Union for Most Developed, scoring 95.37 on the Human Development Index.
