Hmmm... A Traveller campaign based on a Bourne Identity type of theme - with characters pre-generated by the Referee with extensive skills and assets they get to discover along the way.
Great excuse for the Referee to throw things at them from nowhere (leading back to their connected pasts) - with little explanation or backstory. It could turn out that the characters are mortal enemies (maybe nobility, maybe disquised alien species) who the Referee manipulates into fighting against their own peoples and their own inheritance!
