The Empire of Tyranthor is a colossal, socially progressive nation, ruled by Chapter Master Khasan Teliodexus with an even hand, and renowned for its pith helmet sales, compulsory military service, and complete absence of social welfare. The hard-nosed, hard-working, devout population of 3.797 billion Tyranthorians enjoy some of the most opulent lifestyles in the region, unless they are unemployed or working-class, in which case they are variously starving to death or crippled by easily preventable diseases.

The relatively small, liberal, pro-business government juggles the competing demands of Spirituality, Defense, and Education. It meets to discuss matters of state in the capital city of Nocturne. Citizens pay a flat income tax of 9.3%.

The very strong Tyranthorian economy, worth 200 trillion Laizus a year, is broadly diversified and led by the Furniture Restoration industry, with major contributions from Basket Weaving, Information Technology, and Book Publishing. Average income is 52,900 Laizus, but there is a significant disparity between incomes, with the richest 10% of citizens earning 159,725 per year while the poor average 13,648, a ratio of 11.7 to 1.

Fire Drake is one of the most popular forenames in Tyranthor, signs at the border tell international drivers where they can put their cars, colonists who were promised new lands find only war-torn devastation, and same-sex marriages are increasingly common. Crime is moderate, with the police force struggling against a lack of funding and a high mortality rate. Tyranthor's national animal is the Fire Drake and its national religion is Imperial Truth.

Tyranthor is ranked 111,639^th in the world and 5^th in Thee Imperium of Man for Most Developed, scoring 59.21 on the Human Development Index.
