The Cambrian Chronicles of Ternyllwg is a colossal, efficient nation, ruled by Annwn Ddu with a fair hand, and notable for its burgeoning eagle population. The hard-nosed, hard-working, democratic population of 3.079 billion Ternyllwgians live in a state of perpetual fear, as a complete breakdown of social order has led to the rise of order through biker gangs.

The tiny, liberal, pro-business government prioritizes Defense, although Law & Order, Welfare, and Healthcare are also considered important, while International Aid and Spirituality aren't funded at all. It meets to discuss matters of state in the capital city of the Lost Lands of Lloegr. Citizens pay a flat income tax of 8.2%.

The thriving Ternyllwgian economy, worth 178 trillion Iolo manuscripts a year, is led by the Gambling industry, with significant contributions from Furniture Restoration, Arms Manufacturing, and Woodchip Exports. Average income is 57,992 Iolo manuscripts, but there is a significant disparity between incomes, with the richest 10% of citizens earning 205,273 per year while the poor average 11,829, a ratio of 17.4 to 1.

The tenet of free speech is held dear, the military perceives nations hit by natural disasters as "easy pickings", Annwn Ddu has just been declared ruler of Ternyllwg in an international press conference, and the government has declined to declare any particular religion as its 'official' one. Crime is a serious problem, with the police force struggling against a lack of funding and a high mortality rate. Ternyllwg's national animal is the eagle, which can occasionally be seen dodging aircraft in the nation's cities, and its national religion is Crusader Kings II.

Ternyllwg is ranked 239,711^th in the world and 4^th in Nova Libertatia for Most Eco-Friendly Governments, scoring 109.97 on the Dolphin Recycling Awareness Index.
