The Grand Empire of Sol Luna is a massive, efficient nation, ruled by King Francis II with an even hand, and renowned for its prohibition of alcohol, anti-smoking policies, and punitive income tax rates. The compassionate population of 3.054 billion Sol Lunans have some civil rights, but not too many, enjoy the freedom to spend their money however they like, to a point, and take part in free and open elections, although not too often.

The large government juggles the competing demands of Education, Administration, and Law & Order. It meets to discuss matters of state in the capital city of Lunar City. The average income tax rate is 69.1%, and even higher for the wealthy.

The all-consuming Sol Lunan economy, worth 325 trillion Solarias a year, is broadly diversified and led by the Information Technology industry, with significant contributions from Book Publishing, Tourism, and Furniture Restoration. Average income is an impressive 106,601 Solarias, and evenly distributed, with the richest citizens earning only 3.0 times as much as the poorest.

Construction of the Really Big Hadron Collider is underway, King Francis II is described as an everyday person with normal tastes and the usual interests, Sol Lunan doors require a Ph.D. to open, and untold millions of Solarias are going into a new government-funded maternity leave scheme. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Sol Luna's national animal is the Gravitas Hummingbird, which soars majestically through the nation's famously clear skies, and its national religion is Lunarian Faith.

Sol Luna is ranked 17,081^st in the world and 1,052^nd in Osiris for Most Advanced Public Education, scoring 8,686.59 on the Edu-tellignce® Test Score.
