The United Overlordship of Castino is a colossal, safe nation, ruled by The Hangman with an iron fist, and notable for its barren, inhospitable landscape, frequent executions, and compulsory gun ownership. The hard-nosed, hard-working, cynical, humorless, devout population of 2.526 billion Castinians are kept under strict control by the oppressive government, which measures its success by the nation's GDP and refers to individual citizens as "human resources."

The medium-sized, corrupt, well-organized government juggles the competing demands of Defense, Education, and Administration. It meets to discuss matters of state in the capital city of Burgundy. The average income tax rate is 78.3%.

The frighteningly efficient Castinian economy, worth 399 trillion National Default Credits a year, is broadly diversified and led by the Information Technology industry, with major contributions from Arms Manufacturing, Book Publishing, and Retail. Average income is an impressive 158,312 National Default Credits, with the richest citizens earning 5.2 times as much as the poorest.

Cheap goods stamped "Made In Dàguó" are increasingly rare, classes are regularly interrupted by drunken children, organisations with 800 in their phone number are often raided by special forces, and choice roles for female actors involve asking "Is there anything I can do for you?". Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Castino's national animal is the Dragon, which teeters on the brink of extinction due to toxic air pollution, and its national religion is Kivuism.

Castino is ranked 38,257^th in the world and 109^th in Concord for Most Eco-Friendly Governments, scoring 2,330.15 on the Dolphin Recycling Awareness Index.
