Thronebreaker: The Witcher Tales - Ep. 2 Ch. 1 Pt. 1 (4K, Commentary) 

So this is the beginning of Thronebreaker, A witcher story. This is set sometime before Witcher 2 and focuses on the story of Meve, the Queen of Lyria and Rivia (where Geralt is from). I did not realize it but it's basically Gwent wrapped in a world map.
