You start in by getting elected Mayor, Sheriff, Manager, Treasurer, Dominar, whatever the place has as it's most powerful leadership position. It'll probably take at least 3 or 4 of adventures to get here, and there should be some GoT type maneuvering going on, optimally with the end being that it looks like your character did something horribly underhanded but no one can prove it (work the the GM for this).

Now you just slowly slid down the hill. Start with some kind of simple disputes over things like resources. The power station manager wants to charge higher prices, or the nerf ranchers up on Boonta Mesa keep fouling the towns water supply with nerf waste. You settle the dispute by doing something to get the land/facility out from under the owner, rezoning, market buying, whatever. In the end this should still keep everyone else happy though.

Next have it get a little more weird. A mysterious stranger comes to down and causes (understable) problems, but problems nonetheless. A shootout in town with the local wild bunch, bar brawl with a migrant gambler, something like that. Your take action to get rid of the problem, and he responds by coming back with his old gang. You defeat them, but decide to hire on some extra muscle to prevent a repeat. Beign a small outpost you're not exactly going to be able to afford a first class operation like First Sun, and instead settle for some Aqualish, Weequay, and maybe a gamorrean or two.

A few more conventional Adventures take place, but with the GM dropping in some flavor, like the Gamorreans always ending up in jail the night after payday, the local cantina owner demanding the town government pay for the furniture the Aqualish keep breaking over eachothers heads, and the innkeeper complaining about the smoke, funky smell, and inane giggling always coming from the Weequay's rooms. At some point you find some unobtainium deposits in the Verple river valley. Cap this with a low-level young Hutt trying to make a name for himself making a move on the town, and the new muscle actually working out, partly by fighting off the invaders, partly by beating up the local townsfolk that were thinking a change in government might not be so bad.

Now.... Nat Farlander and his brother Khip, comes rolling into town. He's a 30 somethign with a shady past (possible former Imperial, Rebel, Smuggler, whatever fits the character and campaign) and is looking to visit his sister who runs the nerf ranch down by the Verple River before moving on to some boomtown on the edge of wildspace. He's even brought some friends who are interested in the same. A former rough and tumble type that is looking for work as a peacekeeper, and is disgusted by your thugs lack of discipline. An old retired general that wants to open a vineyard and make qualta-wine... whatever works. Of course in a previous adventure we establish this as prime real estate that you want for yourself to help fund further build ups.This one can end with a showdown at high noon...

Finally you close it out with the Empire showing up in force, with orders to nationalize your shiny new unobtainium mine. They're willing to offer you reasonable compensation.... of course Imperial law requires they pay it to the town leadership, and it's the leadership's responsibility to dispense it out to the population fairly. If you give it out to all the locals they'll have enough to move back coreward, or resettle on a newly terraformed world a few systems over.

On the other hand... if you keep most of the credits for yourself you'll have enough to pay off the Hutts AND still be left with enough left over to buy a big place on a lake outside of Theed and retire....
