Berez

Berez was once one of the main three settlements in Barovia, founded around the same time as Vallaki and Krezk, and predating the founding of the village of Barovia. It was destroyed long ago by Strahd, allegedly due to his getting angry over some woman again — as Sylvain has noted, this is a recurring theme for the Lord of Barovia.

How long ago Berez was destroyed is unknown — Bren suggested it was around 200 years ago, but whether that's in Barovian time or Faerûnian time is hard to say. According to The Fall of Berez, the village was destroyed 150 years ago.

Berez's current state is a mystery to our heroes beyond one fact: the dreaded witch Baba Lysaga lives there, making it a place that — according to Davian Martikov's assessment — should be avoided at all costs. It is in the central part of Barovia, south of the haunted mansion by Vallaki, beside the Luna River.
