The Heavenly Kingdom of Caladann is a massive, cultured nation, ruled by King Leto with an even hand, and notable for its museums and concert halls, national health service, and frequent executions. The compassionate, cynical population of 1.77 billion Caladannis 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 Administration, Healthcare, and Education. It meets to discuss matters of state in the capital city of Arrakis. The average income tax rate is 73.8%, and even higher for the wealthy.

The frighteningly efficient Caladannian economy, worth 187 trillion dollars a year, is fairly diversified and led by the Information Technology industry, with major contributions from Tourism, Arms Manufacturing, and Book Publishing. State-owned companies are common. Average income is an impressive 105,729 dollars, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Police officers have been re-kitted with designer uniforms and gold-plated handcuffs, married couples must call each other "darling" or risk a fine, fighter pilots crash out of the air after failing to understand their foreign instruction manuals, and fishermen take out second mortgages to afford the yearly fishing permit. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Caladann's national animal is the Eagle, which soars majestically through the nation's famously clear skies, and its national religion is Cult of the Eagle King.

Caladann is ranked 14,904^th in the world and 843^rd in The North Pacific for Most Developed, scoring 87.31 on the Human Development Index.
