The Heavenly Kingdom of Caladann is a massive, genial nation, ruled by King Leto with an even hand, and notable for its pith helmet sales, unlimited-speed roads, and sprawling nuclear power plants. The compassionate population of 1.521 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 71.3%, and even higher for the wealthy.

The frighteningly efficient Caladannian economy, worth 168 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 110,978 dollars, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Caladannian novella fans become unusually flustered when thinking about King Leto, serial killers who are released early distribute death but not their seed, the hills are alive with the smell of burning flesh, and where there's a will there is usually a password manager. 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 17,372^nd in the world and 932^nd in The North Pacific for Most Popular Tourist Destinations, with 1,439.77 Tourists Per Hour.
