The Disembodied Heads of Thasus IV is a gargantuan, safe nation, ruled by A Non-Corporeal Green Head with an even hand, and notable for its ban on automobiles, daily referendums, and stringent health and safety legislation. The compassionate, humorless population of 10.329 billion Thasians 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 medium-sized government is primarily concerned with Administration, with Education also on the agenda, while Defense and Law & Order are ignored. It meets to discuss matters of state in the capital city of A Translucent Insubstantial Metropolis. The average income tax rate is 17.6%, but much higher for the wealthy.

The sizeable but inefficient Thasian economy, worth 54.7 trillion Federation Credits 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 a slick, highly efficient, extremely specialized black market in Basket Weaving. 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 5,294 Federation Credits, and evenly distributed, with the richest citizens earning only 2.4 times as much as the poorest.

Gym teachers instruct advanced-level calculus classes, toast never burns but always has a weird chemical taste, young people avoid opening doors for the elderly with impunity, and A Non-Corporeal Green Head is rumored to have teleportation powers. Crime, especially youth-related, is totally unknown. Thasus IV's national animal is the Psychokinetic Human, which frolics freely in the nation's many lush forests, and its national religion is Transcendentalism.

Thasus IV is ranked 58,844^th in the world and 31^st in United Earth Space Probe Agency for Highest Food Quality, scoring 30.99 on the Meeshlin-Starr Index.
