What's your favourite Background?
...and I don't mean from the viewpoint of playability or efficiency, I mean from the viewpoint of "flavour".
Mine is the Ratcatcher.
I always think about how one would recruit a ratcatcher for a band of cutthroat sellswords. Like first day on the battlefield: "You goddamn arsewipe Liar!! You told me you had some vermin to kill!! Those are goddamn direwolves! I'm gonna die! Fuck this, I am out of here!" "Get your arse to the frontline, rat-boy or Eberhard here will see to it that these are the last direwolves you ever saw, If you get my meanin'" :)
Or the gambler. What could get a gambler to go to a mercenery band?
"Darn it. Lost too much last night. Ludwig is gonna brake my kneecaps. Got to make some coin. How hard can it be?" Or because of the high resolve: "I tell you, I'm done playing with dice. Bring it on. I need some real stakes"
