I was thinking a human smuggler/gun slinger who made a lil (big) fucky wucky on a delivery for an Yrrkradian warlord. Maybe said warlord might've been a bit closer with the emperor than smuggleman assumed. Big bad consequences for failure IE whole crew gets merced to make an example. So now he's officially in the shits with a highly influential Yrrkradian politician or two due to the consequences of said delivery not making it. Likely something that screwed a loyalist war effort or left them lacking supplies of some kind. He wants vengeance and they think he's dead kinda thing.
