I'm working on my first campaign as a GM, and I'm currently fleshing out the details of the world where most of the action will take place. There's a large conspiracy involving all ranks of government on this bustling hive world, and so my question for you guys is: what sorts of planet-wide government figures would you expect to find on a "typical" hive planet? For example, you have the planetary governor, but what would be the "line of succession" after that? What other bureaucratic figures might you, as a PC, think to seek out in the course of investigating a government wide conspiracy? I know improvisation is needed for some of this, but I don't want to be completely stumped if a PC in my group asks to go speak to the head of such-and-such department that I never even thought of.
Any and all input is appreciated! Thanks guys!
