The Empire of Primarch is a titanic, safe nation, renowned for its compulsory military service and irreverence towards religion. The hard-nosed, cynical population of 22.519 billion Space Marines 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, well-organized government juggles the competing demands of Law & Order, Defense, and Social Policy. The average income tax rate is 43.2%, but much higher for the wealthy.

The Primarchian economy, worth 896 trillion Credits a year, is broadly diversified and led by the Automobile Manufacturing industry, with major contributions from Tourism, Retail, and Arms Manufacturing. State-owned companies are reasonably common. Average income is 39,798 Credits, and evenly distributed, with the richest citizens earning only 2.1 times as much as the poorest.

Bicyclists are banned from major roads, TV shows must meet strict ethnicity quotas, military spending recently hit a new high, and high-income earners pay a 100% tax rate. Crime, especially youth-related, is totally unknown, thanks to the all-pervasive police force and progressive social policies in education and welfare. Primarch's national animal is the Ouroboros.

Primarch is ranked 276,943^rd in the world and 10^th in Aura Hyperia for Highest Disposable Incomes, with 22,605.42 Standard Monetary Units.
