The Realm of Poseidon is a mammoth, environmentally stunning nation, ruled by Poseidon with an iron fist, and notable for its museums and concert halls, ban on automobiles, and prohibition of alcohol. The hard-nosed, cynical population of 8.939 billion Poseidonians are ruled by a mostly-benevolent dictator, who grants the populace the freedom to live their own lives but watches carefully for anyone to slip up.

The large, corrupt, well-organized government juggles the competing demands of Education, Environment, and Defense. It meets to discuss matters of state in the capital city of The Ocean. The average income tax rate is 91.6%.

The frighteningly efficient Poseidonian economy, worth a remarkable 1,550 trillion dollars a year, is quite specialized and led by the Tourism industry, with major contributions from Information Technology, Book Publishing, and Arms Manufacturing. Black market activity is extensive. State-owned companies are common. Average income is an impressive 173,490 dollars, and evenly distributed, with the richest citizens earning only 3.7 times as much as the poorest.

Droves of former desperados are applying to join the border police, Poseidon has one of the largest offshore wind farms in the world, nature magazines featuring stick insects on their covers are sometimes mistaken for fashion magazines, and explicit slash fiction is repackaged for kindergarten kids as stories about friends cuddling friends. Crime is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Poseidon's national animal is the dolphin, which frolics freely in the nation's sparkling oceans, and its national religion is The Cult Of Poseidon.

Poseidon is ranked 2,801^st in the world and 4^th in Greece for Largest Publishing Industry, scoring 23,389.79 on the Bella Potter Productivity e-Index.
