I finally got my copy of Rogue Trader from Amazon today. (Took them long enough!) Since I'm the one who bought the book, I'll be petitioning our GM to let me be the ship captain.
I'm trying to come up with a decent backstory for my Rogue Trader. My DH Adepta comes from a noble background, and my Star Wars RPG character is a noble, too. I'm trying to figure out a feasible way to not be a noble this time around. I'm thinking of having her come from an Imperial world, but how would she have gotten control of a ship with a Warrant? I'm leaning toward a Vaunted birthright. Either that or Child of the Creed, since our DH Inquisitor will have an ongoing relationship with our Explorers to find relics for him that will play into storylines for our Acolytes. (In any given game session, our GM said that we could be playing either our DH Acolytes or RT Explorers.)
So yeah... how would a non-noble end up captaining a rogue trader ship?
