Sunskirt, My nation is incredibly different, it's like Omega from ME3, or a spacestation filled with lowlifes and smugglers and stuff. Brief overviewAnywho, how would I edit the sheet to make it fit in?

As far as the first three lines go, it should be fairly easy. What is their political status in the galaxy, who leads it, and what form of government is it?
The next three should be easy too, just the total employed, and military populations. As far as employed, I would say anyone who makes a living off of their "career" in the space stations. Anyone who does anything to benefit themselves and the economy, such as smugglers, spies, "Scientists for Hire" etc would be considered employed. I'm assuming your space station(s?) has roof for a military force, it should, and therefore just list how many people work in your armed forces.

Biography of Political Leader is straightforward, and as far as the Notable Figures and their background info go, I'd say anyone who benefits heavily to the economy or military or politics or whatnot; targets other nations would want to take out, and individuals that benefit the Underworld. Any elite agents or commanders, heavily revered smugglers or scientists, etcetera.

Main and side species information, what lives on the space station (typically this section would be for intelligent species, but since you operate on what looks like a (or a series of) space stations/battlestations solely, I'd say really any species worth mentioning (non-intelligent would go in Side Species, of course).

In the Economic Overview, just try to explain how your economy is. Do you have any trade routes, what are frequent exports, imports, etcetera. Note that you aren't just limited to material ex/imports, you can ex/import stuff such as political intrigue, espionage, technology, literal currency, etcetera.
Militaristic Overview would just contain what forces you have on your space station(s?) to defend the Underworld. Any cannons or turret regimes, shields, etcetera, as well as armies, ships, and star-forces. The political overview would be more difficult, maybe just public opinion, how much your internal political pressure effects the Underworld, more about the government, etcetera. Is it lead by a band of thieves, or smugglers, or marauders, or a more organized government? Possibly an anarchist state, you make it up here.

Home Worlds could just be the main space station/battlestation(s?), with descriptions about how big they are, what they are made of, population densities and other important informations, and notable planets could be more minor city ships or space stations if you have any. Or, if your nation does control planets, put them in the appropriate section as well.

Seeing as you're a naton 'on the move', the number of Star Systems under your control would probably be quite small, one at the least. Number of planets under your control means just that, but it does not involve space stations. If you want, you can include a separate line in that paragraph "Number of Stations under your influence" or whatever, to count how many you own. You possibly have colonies, so make sure to list those too.

Finally, a brief history of your nation would include what has happened to them, how they developed, when they moved out onto space stations and city ships and whatnot, and include any other current "miscellaneous information" here, too, if you wanted to include what you said on the Interest Check here, you can, but I'd try summarizing it a bit.

Anyways, thats how I would suggest you fill it out for your nation. I really like the uniqueness of your nation, living solely on a space station or city-ship or a few, with smugglings and crimes and stuff. It's very interesting, but may be difficult to map out. We'll figure something out! :)

Hope this helped.
Oh, and its ShinySurskit, but it doesn't really matter. :)
Good night
