The headmistress got help from the Pack in Curse Of Strahd, informing them of the strange happenings occurring since the arrival of Felix Zsoldos and eventually notifying them of his mysterious locket. They used this to slay the Shadow Demon that had taken hold of the boy, and the Headmistress was ashamed she had not been able to see it. She later learned from them that the ordeal was part of a greater conspiracy to deconsecrate the church, but through the heroes' actions, this disaster was averted.
From then on, Klavidya was extremely warm to The Pack, especially Ghalwin of the Grove, as they continually provided food and funds to the orphanage. Their support allowed her to repair the grounds and provide proper nourishment to the children, and they ensured the orphanage stayed safe during the Riots Of The Blazing Sun.
