The Holy Empire of Diocean School is a massive, genial nation, ruled by Patriarch-Headmaster Ronnieus Barneius with an even hand, and notable for its pith helmet sales, avant-garde cinema, and daily referendums. The compassionate, democratic, devout population of 1.83 billion Diocesans are prohibited from doing almost everything except voting, which they do timidly and conservatively.

The enormous, socially-minded government prioritizes Administration, with Education, Defense, and Industry also on the agenda. It meets to discuss matters of state in the capital city of Schoole Halle. The average income tax rate is 91.4%, and even higher for the wealthy.

The frighteningly efficient Diocean Schoolian economy, worth 249 trillion DC forms a year, is led by the Arms Manufacturing industry, with major contributions from Book Publishing, Beef-Based Agriculture, and Tourism. State-owned companies are common. Average income is an impressive 136,230 DC forms, and distributed extremely evenly, with little difference between the richest and poorest citizens.

The government has adopted a "Lightning Never Strikes Twice" approach to dealing with natural disasters, school history books often refer to Patriarch-Headmaster Ronnieus Barneius as "that imperialist pig dog", the aims of top-secret Diocean Schoolian science projects revolve around designing the perfect robot woman, and paranoid museum guards keep a lookout for any animated displays attempting to escape the premises after dark. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Diocean School's national animal is the coffee-fueled student, which is also the nation's favorite main course, and its national religion is Catholicism.

Diocean School is ranked 32,856^th in the world and 2^nd in Basileia Rhomania for Highest Average Incomes, with 136,230.57 Standard Monetary Units.
