The United Socialist States of Sol- is a mammoth, socially progressive nation, notable for its frequent executions, free-roaming dinosaurs, and ubiquitous missile silos. The compassionate population of 5.47 billion Solites are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The large, socially-minded government juggles the competing demands of Education, Administration, and Industry. The average income tax rate is 98.1%.

The frighteningly efficient Solarian economy, worth a remarkable 1,203 trillion Ergs 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 significant contributions from Tourism, Arms Manufacturing, and Book Publishing. Average income is an amazing 220,025 Ergs, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

The "swords to plowshares" policy has created a generation of farmers that can kill a yak from 200 yards away, therapists can always squeeze in another house-call, men are finding 'she spots' more easily but they can't use them, and the government builds houses for foreign newcomers. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Sol-'s national animal is the Human, which frolics freely in the nation's many lush forests.

Sol- is ranked 1,818^th in the world and 20^th in The Communist Bloc for Most Scientifically Advanced, scoring 851.25 on the Kurzweil Singularity Index.
