[Source] Count Martin Monnier of Beauclair is a famous Gwent lover as well as a co-creator behind the Skellige deck. When his brother was alive, they both traveled to the Skellige Islands and they were so amazed that they decided to create a deck inspired by the history of the archipelago. If Geralt beats Hamal ogn Dangbahli and Ambassador von Hinn, he will face off against Martin, who will use his beloved faction.
