In Curse Of Strahd, Bella took Tessa Nicoleva from her mother in exchange for Dream Pastry; this caught the attentions of The Pack, as they had grown close to the girl at Saint Andral's Orphanage. They followed her trail using the help of the Keepers of the Feather, who's spy Laszlo Lazarescu had been keeping tabs on Old Bonegrinder. They raided the mill from the third floor, where Offalia was the first to be attacked. The hag fled downstairs but was eventually caught in combat; she was summarily then ripped apart by Shakti of the Wildhunt, who had Wildshaped into a Cave Bear.
Her body was later burned by Ghalwin of the Grove, to ensure she could never come back.
