The Grand Duchy of San Arcadio is a huge, safe nation, ruled by Grand Duke St Arcadius the Great with an even hand, and remarkable for its sprawling nuclear power plants, state-planned economy, and devotion to social welfare. The compassionate, democratic population of 771 million San Arcadians enjoy extensive civil freedoms, particularly in social issues, while business tends to be more regulated.

The large government juggles the competing demands of Education, Healthcare, and Administration. It meets to discuss matters of state in the capital city of San Arcadio. The average income tax rate is 74.9%, and even higher for the wealthy.

The all-consuming San Arcadioan economy, worth 77.9 trillion Denaris a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector is led by the Information Technology industry, with major contributions from Trout Farming, Tourism, and Beef-Based Agriculture. Average income is an impressive 101,047 Denaris, and distributed extremely evenly, with little difference between the richest and poorest citizens.

The national guard is mobilized whenever a mother gets separated from her child at the mall, vital intelligence-gathering activities are often put on hold for Call of Honor tournaments, citizens no longer take selfies with their dead relatives at funerals, and worried-looking neonatal nurses are being deployed in place of SWAT teams during dangerous drug busts. Crime, especially youth-related, is totally unknown. San Arcadio's national animal is the Golden Eagle, which soars majestically through the nation's famously clear skies.

San Arcadio is ranked 36,469^th in the world and 906^th in the South Pacific for Most Efficient Economies, scoring 96.44 on the Krugman-Greenspan Business Outlook Index.
