The Associate Custodianship of Esterlon is a gargantuan, efficient nation, ruled by Deputy-General Johanna Morris with an even hand, and renowned for its multi-spousal wedding ceremonies, flagrant waste-dumping, and stringent health and safety legislation. The hard-nosed, humorless population of 25.074 billion Esterlonians are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The relatively small, corrupt, socially-minded government juggles the competing demands of Industry, Defense, and Education. It meets to discuss matters of state in the capital city of Ambersyell. The average income tax rate is 54.1%, and even higher for the wealthy.

The frighteningly efficient Esterlonian economy, worth a remarkable 8,991 trillion NationStates Dollars a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. However, for those in the know, there is an enormous, deeply entrenched, fairly diversified black market in Information Technology, Uranium Mining, Retail, and Woodchip Exports. The private sector mostly consists of enterprising ten-year-olds selling lemonade on the sidewalk, but the government is looking at stamping this out. Average income is an amazing 358,581 NationStates Dollars, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

Students can name the chiefs of proto-Bigtopian tribes before they can count to ten, government leaders testify at international tribunals on why the sun went out, rebuilding efforts for a recently destroyed cathedral aren't expected to be completed for another century, and it takes several hours to shuffle the national deck. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Esterlon's national animal is the Pigeon, which teeters on the brink of extinction due to toxic air pollution.

Esterlon is ranked 331,180^th in the world and 19^th in New Hyperion for Most Compassionate Citizens, scoring 8.56 on the Kitten Softness Rating.
