The Holy Empire of The Last Primarch is a colossal, orderly nation, renowned for its burgeoning Eagle population. The cynical population of 9.911 billion Marians 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, moralistic, socially-minded, well-organized government juggles the competing demands of Law & Order, Defense, and Welfare. The average income tax rate is 41.2%, but much higher for the wealthy.

The large but underdeveloped Last Primarchian economy, worth 234 trillion Credits a year, is quite specialized and led by the Trout Farming industry, with significant contributions from Soda Sales, Information Technology, and Retail. Black market activity is notable. State-owned companies are common. Average income is 23,702 Credits, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Crime is totally unknown, thanks to a very well-funded police force and progressive social policies in education and welfare. The Last Primarch's national animal is the Eagle.

The Last Primarch is ranked 192,396^th in the world and 13^th in The Alpha Legion for Largest Publishing Industry, scoring 339.65 on the Bella Potter Productivity e-Index.
