a good map is key
for example, you will see above the territorial limits of authority of the
HM Imperial Region of Pacifica Australis
Independent: Of course not! We are loyal citizens of the Empire!
Leader: Governor General Dekius Leo
Government: Federal Parliamentary
Economic System: Free market welfare state
Society: Reasonably egalitarian and prosperous. Of course there are those malcontents who would be unable to stand up on their own feet if the King Himself offered them His hand, but that lot are kept relatively quiet, pacified, and isolated from decent society.
A high degree of mechanization and automation is in use, especially in the ocean colonies, but men, women, and children still apply themselves vigorously in the mental, athletic, and social disciplines. We certainly won't be having computers doing our thinking for us!
Values: Freedom, order, security, prosperity, the usual lot, plus generosity, dignity, honour, friendliness, civility...
Region: HM Imperial Region of Pacifica Australis, Comprising the Lands of the Australian Continental System and the Waters, Deep and Shallow, of the Great Southern Pacific and all HM Citizen-Residents, Materials, Natural Features, and Aerospace therein, by the Grace of Our King George XXVI, His Court, and His Royal Parliament.
Other Information (History, etc):
The Loyal Subjects of the Australian Continent and its major outlying landforms were tasked with shepherding the peoples and materials crossing the great expanse of the southern and mid Pacific.
The growth of Island Cities, Shallow Water Settlements (and Deep Seas Habitation Projects) and the ensuing prosperity and dynamism those generated have placed some stress on the government system to manage these rather irregular groups of peoples in their quite irregular environments.
We've now developed new paradigms for successfully governing such regions, and most of the kinks have been worked out and we now coexist quite nicely, even if the Oceaners look upon the Landed as somewhat staid and simple and the Landed regard the Oceaners as tending towards rather queer habits and puzzling affectations.
Overall we are a loyal and successful province, but of late we have had some of our efforts with regard to technological advancement, exploration, or social organization denied authorization by the Imperial Bureaucracy, which is getting a little frustrating...
Due to our Region's location and history of settlement, we have significant numbers of just about every ethnic group on Earth, with our most populous group having only slightly greater numbers than the next most populous which is only slightly larger than the next most numerous and so on.
Almost all of them speak, write, and read the King's English, and many have second and third languages, either for academic or business purposes or as relics of their ancestry. Thus many individuals will practice "traditional" customs, but remain good, functioning citizens well adjusted to the ways of the Empire. There are occasionally some racial or cultural tensions but those are the exception, not the norm.
