The Fourth Empire of Salish-Cascadia is a gargantuan, genial nation, ruled by HIM Lewis III Andromeda with an even hand, and renowned for its keen interest in outer space, anti-smoking policies, and irreverence towards religion. The compassionate, humorless population of 25.826 billion Cascadians enjoy extensive civil freedoms, particularly in social issues, while business tends to be more regulated.

The medium-sized, liberal government juggles the competing demands of Education, Environment, and Defense. It meets to discuss matters of state in the capital city of Victoria. The average income tax rate is 47.8%, but much higher for the wealthy.

The Cascadian economy, worth a remarkable 1,726 trillion Salish Imperials a year, is extremely specialized and mostly made up of the Book Publishing industry, with significant contributions from Information Technology. State-owned companies are common. Average income is 66,855 Salish Imperials, and distributed extremely evenly, with little difference between the richest and poorest citizens.

It is illegal to distribute Girl Guide Cookies without an advanced food hygiene diploma, tourists often cite 'hiding money in an off-shore banking account' as their main reason to visit the nation, HIM Lewis III Andromeda has no checks and balances after the upper house was abolished, and social media sites prompt users to send birthday greetings to unresponsive nonagenarians. Crime, especially youth-related, is a major problem, probably because of the absence of a police force. Salish-Cascadia's national animal is the Kraken, which frolics freely in the nation's sparkling oceans.

Salish-Cascadia is ranked 21,452^nd in the world and 852^nd in The North Pacific for Most Scientifically Advanced, scoring 269.14 on the Kurzweil Singularity Index.
