The Medium Rare Salted Steak of Serloin is a massive, cultured nation, ruled by Saburo Arasaka with an even hand, and renowned for its museums and concert halls, frequent executions, and pith helmet sales. The compassionate, democratic population of 2.705 billion Serloinians are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The medium-sized government juggles the competing demands of Administration, Defense, and Education. It meets to discuss matters of state in the capital city of Salted Medium Rare Serloin City. The average income tax rate is 81.1%, and even higher for the wealthy.

The frighteningly efficient Serloinian economy, worth 415 trillion Dollah Beills a year, is broadly diversified and led by the Tourism industry, with significant contributions from Arms Manufacturing, Information Technology, and Book Publishing. Average income is an impressive 153,495 Dollah Beills, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

Companies have begun running campaigns to stop people from remembering their brand name, beaches are empty as the shark population multiplies exponentially, the cruise missile launchers on the field hospital roof are purely deterrent in purpose, and nudity is frowned upon. Crime is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Serloin's national animal is the Pig, which frolics freely in the nation's many lush forests, and its national religion is Drippianity.

Serloin is ranked 18,077^th in the world and 31^st in Spiritus for Most Scientifically Advanced, scoring 296.65 on the Kurzweil Singularity Index.
