For the sake of establishing a plot I think it would be good to start off with a campaign theme, mixing in other themes -- story permitting. Honestly, as long as there's an overall goal (which I assume from the synopsis is to bring peace to the Imperium) I'll be down for any theme. Maybe there'll be a section where our characters are thrust into an arena, or watch observantly in a political party of grandeur trying to locate a target. But just to keep a sense of direction yeah, let's go with a Campaign theme. Our characters are here to complete a set goal, which will be determined more eloquently in the story (as well as their motives). I like the idea of being able to fall back to slice of life every now and then, when the pacing slows and we can really develop our characters because of past tribulations.

Cool beans?
