Around the time you get your stuff back in Vizema, just after the talking to
the King and Yennifer
there is a gentleman sitting the the courtyard with a yellow "!" questmarker on the mini map.
I rushed over, eager to get a new quest, and ended up in a game of Gwent which I only narrowly lost despite having far inferior cards.
The quest icon promptly disappeared and now I am wondering if I lost my chance to get a quest from this guy.
Has anyone beaten him at Gwent and received a quest or is the marker just there to indicate that you can play Gwent with him? I would assume that this is not the case as it disappears after losing.
