Barovia
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.
Geography
Barovia is a mountain valley within the fictional Balinok mountains. The terrain is densely wooded and the climate is one of frigid winters.
The valley hosts a small village (also named Barovia), over which looms Castle Ravenloft, ancestral seat of vampire ruler Strahd von Zarovich.
Fictional history
As originally conceived of in I6: Ravenloft, the history of Barovia mirrors the story of Dracula.
Barovia was conquered at an indeterminate time in the past by Strahd von Zarovich, a vampire wizard.
Sometime around the year 351 of Barovia's calendar, Strahd sought to win the love of a woman named Tatyana. She rebuffed his advances and preferred his brother Sergei. Jealous, Strahd murdered Sergei and sought to claim Tatyana, but she threw herself from the castle walls to her death.
Published products are unclear whether Strahd was a vampire before this event, or whether the tragic events somehow caused him to become a vampire.
