The Closed System of Mithridatium is a titanic, orderly nation, ruled by Lord Terebinth with an iron fist, and renowned for its compulsory military service, hatred of cheese, and stringent health and safety legislation. The hard-nosed, cynical population of 15.312 billion Vadeans are ruled without fear or favor by a psychotic dictator, who outlaws just about everything and refers to the populace as "my little playthings."

The large, corrupt, moralistic, well-organized government juggles the competing demands of Law & Order, Defense, and Healthcare. It meets to discuss matters of state in the capital city of Mrainelial. The average income tax rate is 42.2%, but much higher for the wealthy.

The large but inefficient Vadean economy, worth 511 trillion Units a year, is quite specialized and led by the Trout Farming industry, with major contributions from Arms Manufacturing, Soda Sales, and Door-to-door Insurance Sales. Black market activity is notable. State-owned companies are common. Average income is 33,378 Units, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Abortion is only legal in unusual circumstances, the government subsidises medicines of mass destruction, traffic jams are a common sight due to construction work from a massive overhaul of the nation's freeways, and nerdy teenagers have to prove that they're made of the same stuff as their grandparents. Crime, especially youth-related, is totally unknown, thanks to a very well-funded police force and progressive social policies in education and welfare. Mithridatium's national animal is the Ringlet, which teeters on the brink of extinction due to widespread deforestation.

Mithridatium is ranked 28,875^th in the world and 3^rd in Cymopolia for Largest Populations, with 15.3 billion capita.
