The Vala Ainur of Nienna Lady of Mercy is a massive, efficient nation, ruled by Will of Eru with an even hand, and renowned for its keen interest in outer space, unlimited-speed roads, and punitive income tax rates. The compassionate, devout population of 2.746 billion Nienna are prohibited from doing almost everything except voting, which they do timidly and conservatively.

The large, socially-minded government juggles the competing demands of Law & Order, Defense, and Education. It meets to discuss matters of state in the capital city of Fuisolmar. The average income tax rate is 73.1%.

The all-consuming Nienna economy, worth 245 trillion Light of the Valars a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is fairly diversified, is led by the Arms Manufacturing industry, with significant contributions from Tourism, Information Technology, and Cheese Exports. Average income is 89,558 Light of the Valars, and evenly distributed, with the richest citizens earning only 4.3 times as much as the poorest.

No true communist is an unbeliever, 50% of adverts on children's television are for clothes made of cotton wool, legislators work 24/7 due to an influx of single-issue bills, and the government's fruit business reeks of rotting produce and corruption. Crime, especially youth-related, is totally unknown, thanks to a very well-funded police force and progressive social policies in education and welfare. Nienna Lady of Mercy's national animal is the Secret Fire, which frolics freely in the nation's many lush forests, and its national religion is Faith of Eru.

Nienna Lady of Mercy is ranked 258,277^th in the world and 23^rd in After the Fall for Most Primitive, scoring -129.66 on the Scary Big Number Scale.
