The Empire of Mastruver is a colossal, genial nation, ruled by Mastruvulus with an even hand, and notable for its state-planned economy, punitive income tax rates, and restrictive gun laws. The compassionate, devout population of 6.005 billion Mastruverians are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The enormous government is primarily concerned with Education, with Environment, Law & Order, and Administration also on the agenda, while Defense receives no funds. It meets to discuss matters of state in the capital city of Lyras Cortarius. The average income tax rate is 85.4%, and even higher for the wealthy.

The powerhouse Mastruverian economy, worth 539 trillion Mastruverian denarii a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is highly specialized, is mostly made up of the Book Publishing industry, with significant contributions from Basket Weaving, Information Technology, and Furniture Restoration. Average income is 89,787 Mastruverian denarii, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Bad punctuation has come to a full stop, physics lessons mostly involve talking about emotional management techniques, urban graffiti is hand-calligraphed in perfectly kerned elegant fonts, and the meaning of life was recently discovered in the patch notes for Version 1.42. Crime, especially youth-related, is totally unknown, thanks to the all-pervasive police force and progressive social policies in education and welfare. Mastruver's national animal is the eagle, which soars majestically through the nation's famously clear skies, and its national religion is Roman Catholicism.

Mastruver is ranked 7,116^th in the world and 322^nd in Osiris for Largest Publishing Industry, scoring 15,642.16 on the Bella Potter Productivity e-Index.
