The Closed System of Mithridatium is a titanic, orderly nation, ruled by Lord Terebinth with an iron fist, and renowned for its free-roaming dinosaurs, compulsory military service, and complete absence of social welfare. The hard-nosed, cynical population of 15.468 billion Vadeans are kept under strict control by the oppressive government, which measures its success by the nation's GDP and refers to individual citizens as "human resources."

The large, corrupt, moralistic, well-organized government juggles the competing demands of Law & Order, Defense, and Education. It meets to discuss matters of state in the capital city of Mrainelial. The average income tax rate is 41.2%, but much higher for the wealthy.

The large but inefficient Vadean economy, worth 579 trillion Units a year, is quite specialized and led by the Trout Farming industry, with major contributions from Arms Manufacturing, Soda Sales, and Information Technology. State-owned companies are common. Average income is 37,435 Units, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Claiming that "my cousin said it was legal" is a common courtroom defense, cheap textbooks have replaced coasters at college ragers, pet loving officers arrest citizens who don't give their dogs enough biscuits, and people forget to eat because they are too busy singing Lord Terebinth's praises. 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 266,368^th in the world and 3^rd in Cymopolia for Most Developed, scoring 51.23 on the Human Development Index.
