The Dictatorship of Mercury is a gargantuan, orderly nation, notable for its compulsory military service and complete absence of social welfare. The hard-working, cynical population of 27.124 billion Mercuryians 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, moralistic, well-organized government is primarily concerned with Law & Order, with Industry, Defense, and Education also on the agenda, while Welfare and Spirituality are ignored. Citizens pay a flat income tax of 11.3%.

The very strong Mercuryian economy, worth 883 trillion Sols a year, is broadly diversified and led by the Arms Manufacturing industry, with major contributions from Book Publishing, Automobile Manufacturing, and Uranium Mining. Average income is 32,575 Sols, with the richest citizens earning 8.1 times as much as the poorest.

Elections have been outlawed, the right to free speech is being drastically curtailed, gambling is outlawed, and employers may fire workers without giving any reason. Crime is a problem, possibly because it is difficult to make it through a day without breaking one of the country's many regulations. Mercury's national animal is the Sun dog, which can occasionally be seen sifting through garbage in the nation's cities.

Mercury is ranked 194,680^th in the world and 5^th in The Solar System for Most Beautiful Environments, with 475.76 pounds of wildlife per square mile.
