The Republic of Sendo is a gargantuan, cultured nation, ruled by Sendo with an even hand, and notable for its keen interest in outer space, multi-spousal wedding ceremonies, and public floggings. The hard-nosed, hard-working, humorless, devout population of 18.41 billion Sendoians are highly moralistic and fiercely conservative, in the sense that they tend to believe most things should be outlawed. People who have good jobs and work quietly at them are lauded; others are viewed with suspicion.

The minute, corrupt government, or what there is of one, is effectively ruled by the Department of Law & Order, with Public Transport and Social Policy also on the agenda, while International Aid and Welfare are ignored. It meets to discuss matters of state in the capital city of Gasforth. Income tax is unheard of.

The Sendoian economy, worth a remarkable 2,814 trillion Quid a year, is led by the Arms Manufacturing industry, with major contributions from Retail, Uranium Mining, and Woodchip Exports. Black market activity is extensive. Average income is an impressive 152,905 Quid, and evenly distributed, with the richest citizens earning only 2.4 times as much as the poorest.

The new prison system is crowding up at an alarming rate, employees are told they can avoid traffic jams by starting work at 4 AM, ad hoc militias patrol the streets in an effort to control rampant crime, and in government offices a hidden killer takes the lives of ministers and civil servants. Crime is pervasive, with the police force struggling against a lack of funding and a high mortality rate. Sendo's national animal is the Elk, which is also the nation's favorite main course, and its national religion is Catholicism.

Sendo is ranked 4,596^th in the world and 7^th in NationStates for Most Primitive, scoring 128.97 on the Scary Big Number Scale.
