Storm King's Thunder
Barovia is the name shared by a number of distinct but related locations within the fictional universe of the Dungeons & Dragons roleplaying game. In each of its iterations, the area is loosely based on real-world Transylvania and its associations with the Dracula legend.
Barovia first appeared as the setting of I6: Ravenloft. Later, TSR developed this original adventure into the Ravenloft campaign setting, and writers reconceived of Barovia as one of many domains within the Ravenloft demiplane.
The once lord Strahd was defeating by a band of heroes during the Barovia Incursion, which lead to Silus Von Zarovich taking the crown as the new lord of Barovia.
