Baba Lysaga

Baba Lysaga is an ancient witch residing outside the ruined town of Berez. She lives in a magical hut that is nestled inside an ancient tree animated by the magic of one of the gemstones from the Wizard of Wines vineyard.

According to van Richten, she has a connection with Strahd and the Von Zarovich family dating from before his conquest of Barovia. She claims to be some kind of matronly figure to the vampire but the precise nature of their relationship is unclear

She has an intense dislike of ravens and keeps several imprisoned in her hut. She believes them to be a threat to Strahd.

She is likely behind or a party to the creation of the blight army as well as the massive tree blight the party defeated outside the winery. She is also in possession of one of the gems from the winery which powers her magical hut.

The party were able to surprise and ambush Baba Lysaga in her hut, and nearly defeated her, but a last minute act of trickery allowed her to escape into her flying skull and regain the advantage. The party was forced to flee the battle and Lucstarius was killed in the attempt.
