The Republic of Corumm is a gargantuan, efficient nation, ruled by Brother Leader Linge Chen with an iron fist, and remarkable for its frequent executions, keen interest in outer space, and aversion to nipples. The hard-nosed, hard-working, cynical, humorless population of 30.528 billion Corummese 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 relatively small, corrupt, well-organized government juggles the competing demands of Defense, Law & Order, and Industry. It meets to discuss matters of state in the capital city of Mirzak. The average income tax rate is 71.7%, and even higher for the wealthy.

The frighteningly efficient Corummian economy, worth an astonishing 12,416 trillion Lire a year, is broadly diversified and mostly comprised of black market activity, especially in Arms Manufacturing, Uranium Mining, Woodchip Exports, and Information Technology. State-owned companies are reasonably common. Average income is an amazing 406,733 Lire, and evenly distributed, with the richest citizens earning only 2.3 times as much as the poorest.

It is typical to be greeted by a string of curse words in Corummian restaurants, wars of expansion are described as "peacekeeping operations", the examiners who examine examiners are being examined by examiners, and children play a simplified version of hopscotch. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Corumm's national animal is the Corummese Bear, which teeters on the brink of extinction due to widespread deforestation, and its national religion is the Cult of the Leader.

Corumm is ranked 18,266^th in the world and 1^st in Yanxi for Most Scientifically Advanced, scoring 324.17 on the Kurzweil Singularity Index.
