i cant remember where if it was mentioned by the fanbase or sam her self talking about Karlach potentially running her own tavern?
That was Sam just answering the question of what she thinks Karlach's perfect ending would be. "It'd be kinda boring, but maybe that's what people want right now" (c) (yes)
Don't think that's something we can even remotely expect in canon-canon - that's just one person throwing out an idea after all, and as we know they don't have influence there - but boy did I adopt that into my personal headcanon immediately
And now I’ve adopted it into mine. To the Hellion’s Hearth!
