Lady Beatrice is an NPC from the Game of Crone DLC critical to the ending. She is an inquisitor searching for Marquis Teodoro Jr. and the other residents of the Refugee camp. The Keeper first meets her the day after he talks to Master Alaric about his secret, when she greets him upon waking up and sprays perfume all over Sweet Home before asking about the refugees. She then vanishes in a flash of pink light.
Beatrice will ask you to help her raise an army of ghouls by creating Emulsion of death for her. This decision affects the fate of the refugee camp.
