I thought Barcus Wroot, the Deep Gnome you rescue from goblins, would make a cool camp merchant. Perhaps he still will reappear later, would be odd not to see him again after the event.
Im affraid that Swen have some (quite unpleasant if you ask me
) plans with him ...
They are not yet implemented, but it was datamined ...
He get to the Underdark, and will be enslaved by Duergars ... not sure where will his adventure lead next.
