The Chair Kingdom of Cerdenia is a gargantuan, cultured nation, ruled by King Chair I with a fair hand, and notable for its museums and concert halls, deadly medical pandemics, and smutty television. The hard-nosed, hard-working, democratic population of 11.644 billion Cerdenians live in a state of perpetual fear, as a complete breakdown of social order has led to the rise of order through biker gangs.

The minute, liberal, outspoken government, or what there is of one, prioritizes Industry, although Healthcare is also considered important, while Spirituality and Law & Order are ignored. It meets to discuss matters of state in the capital city of Chairdenia. The average income tax rate is 3.9%, but much higher for the wealthy.

The frighteningly efficient Cerdenian economy, worth a remarkable 1,362 trillion Chaircoins a year, is driven almost entirely by the private sector, which is led by the Retail industry, with significant contributions from Soda Sales, Information Technology, and Uranium Mining. Average income is an impressive 116,996 Chaircoins, and evenly distributed, with the richest citizens earning only 2.6 times as much as the poorest.

Ships no longer sail as no one wants to encounter Cerdenian pirates, traumatised refugees have a full bedpan shoved into their hands along with their immigration papers, the "feminist protest" defence is increasingly common for cases of armed robbery, and most Cerdenians would sell their own grandmother. Crime, especially youth-related, is all-pervasive, probably because of the absence of a police force. Cerdenia's national animal is the Flying Chair, which teeters on the brink of extinction due to toxic air pollution, and its national religion is Cult of the Chair.

Cerdenia is ranked 46,975^th in the world and 80^th in Thaecia for Most Scientifically Advanced, scoring 156.04 on the Kurzweil Singularity Index.
