The Pony Principality of Princess Luna is a gargantuan, cultured nation, renowned for its state-planned economy, hatred of cheese, and devotion to social welfare. The compassionate, devout population of 33.346 billion Ponies enjoy extensive civil freedoms, particularly in social issues, while business tends to be more regulated.

The government — a sprawling, bureaucracy-choked morass — juggles the competing demands of Environment, Healthcare, and Education. It meets to discuss matters of state in the capital city of Coltchester. The average income tax rate is 92.5%, and even higher for the wealthy.

The frighteningly efficient Principalitan economy, worth a remarkable 2,816 trillion Silver Bits a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is extremely specialized, is mostly made up of the Book Publishing industry, with significant contributions from Information Technology. Average income is 84,459 Silver Bits, and distributed extremely evenly, with little difference between the richest and poorest citizens.

T-shirts displaying a photo of Leader performing the Full-Monty are selling out, sales of pregnancy testing kits are booming, sales of disinfectant wipes have skyrocketed, and the alien invasion siren sounds eerily like a UFO. Crime is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Princess Luna's national animal is the Vampire Fruit Bat, which soars majestically through the nation's famously clear skies, and its national religion is Orthodox Harmonism.

Princess Luna is ranked 9,115^th in the world and 9^th in Pony Lands for Most Developed, scoring 91.12 on the Human Development Index.
