The Res Publica Sanctus of Deus Sol Invicto is a gargantuan, socially progressive nation, ruled by Caesar Augustus Ry with an even hand, and notable for its deadly medical pandemics, pith helmet sales, and absence of drug laws. The hard-nosed, cheerful population of 38.821 billion Mithrasists enjoy extensive civil freedoms, particularly in social issues, while business tends to be more regulated.

The medium-sized government juggles the competing demands of Education, Healthcare, and Environment. It meets to discuss matters of state in the capital city of Mithraeum. The average income tax rate is 51.4%, and even higher for the wealthy.

The thriving Mithraic economy, worth a remarkable 3,735 trillion denariis a year, is quite specialized and mostly made up of the Book Publishing industry, with significant contributions from Arms Manufacturing and Soda Sales. Black market activity is extensive. State-owned companies are common. Average income is 96,213 denariis, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Raver DJ XStacy holds multiple medical degrees in chillaxing, nature magazines featuring stick insects on their covers are sometimes mistaken for fashion magazines, customers who are not the epitome of politeness always find themselves at the back of the queue, and the nation grinds to a halt for afternoon tea. Crime is pervasive, probably because of the absence of a police force. Deus Sol Invicto's national animal is the Pullus Cibus, which is also the nation's favorite main course, and its national religion is Mithraism.

Deus Sol Invicto is ranked 290,866^th in the world and 4^th in Hadrians Wall for Lowest Crime Rates, with 25.61 law-abiding acts per hour.
