Welp, now I'm mildly obsessed with Karlach as a tavern barkeep. I wouldn't take it as a sign of anything that may actually be added to the game, but as a concept? Sign me up. My urchin Tav would be overjoyed to help running a place in their favorite city.
I can already imagine us strolling in, ordering a beer, and when she asks for payment we wink at her and tell her, "Just put it on my Tav."
