Hołopole
From Witcher Wiki
Hołopole is located among the foothills of Kestrel Mountains. It's a minor land, neighbour to Malleore, Creyden, Kaedwen and Caingorn, and walled in by the Kestrel Mountains to the east and river Braa.
The capital is the city-state of Hołopole, and there's a temple of Kreve downtown.
The short story Granica możliwości (The Border of Possibility) took place in Holopole, and so did the fourth episode of The Hexer tv-series, "Smok" (The Dragon), too.
