Barovia is the oldest domain in Ravenloft. It was formed from a part of the ancestral lands of Strahd von Zarovich at the time when he murdered his brother Sergei to win the hand of the beautiful Tatyana in the year 351 of the Barovian Calendar. Barovia is loosely based on real-world Transylvania. The country is mostly mountainous (the Balinok range) and covered in dense woods. The climate is cold with frigid winters.
