Lavinia Whateley is a young girl with albinism who appears in Fate/Grand Order's Salem chapter. She is based on the character from H.P. Lovecraft's 'The Dunwich Horror' but reimagined within the Fate universe. In the game, she features various motifs derived from Lovecraftian works presented alongside an alternative telling of the Salem witch trials. She is a close friend of Abigail Williams and appears as a non-playable character in the game. While not a playable Servant herself, she was featured in FGO's 10th Anniversary promotional materials.
