"Well, the Emperor's going to want to trade for those portals but he'll be perfectly content to wait for them; out of everyone I know, I think he has the strongest understanding of the inherent responsibilities of a situation like this. My boss will freak out about the fact that you could fairly casually conquer the planet by wandering around asking people politely for their names, but while he can tell me to do things about that and by custom I am supposed to do as he says, in practice this wouldn't be the first time I disagreed with the decisions of someone whose orders I am supposed to follow. As long as you do not actually proceed to conquer the planet, I don't think he'll even threaten me with particularly dire consequences if I tell him to fuck off."
