Construction beginning/end
After five years of construction, the completion of the Von Zarovich family home, named Castle Ravenloft for Count Strahd's late mother, was celebrated. Although the Count had declared the valley an independent state under his rule five years prior, it is the date that the castle was completed that locals consider the true "birth" of Barovia. The year is marked as the beginning of the Barovian calendar, year 0 BR (Barovian Reckoning.)
