The Republic of Regnum Lumen is a mammoth, socially progressive nation, remarkable for its keen interest in outer space, suspicion of poets, and stringent health and safety legislation. The democratic population of 5.982 billion Regnum Lumenians are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The relatively small government juggles the competing demands of Education, Welfare, and Environment. It meets to discuss matters of state in the capital city of Nova Lucerna. The average income tax rate is 20.5%, but much higher for the wealthy.

The large but underdeveloped Regnum Lumenian economy, worth 211 trillion Lyudas a year, is fairly diversified and dominated by the Tourism industry, with significant contributions from Soda Sales, Cheese Exports, and Retail. State-owned companies are common. Average income is 35,360 Lyudas, and evenly distributed, with the richest citizens earning only 2.0 times as much as the poorest.

The government awards prizes to television shows featuring stereotype-breaking minority roles, the nation's navy has been named the scourge of the seven thousand seas, businesses are forced to bring all work back within the nation's borders, and nobody knows why the caged Blue-tailed Sea Turtle sings. Crime is totally unknown. Regnum Lumen's national animal is the Blue-tailed Sea Turtle, which frolics freely in the nation's sparkling oceans.

Regnum Lumen is ranked 242,286^th in the world and 3^rd in LunarPunk for Largest Trout Fishing Sector, scoring -4.9 on the Nemo Depletion Efficiency Index.
