Ariadne LeGrant-Amsberg (born 1913) is a hidden secondary antagonist of Song of Horror. Ariadne is the original owner of the cursed music box, coming into possession of it after her father gifted to her when she was a baby. Soon after coming into possession of the music box, Ariadne's family suffered a "break-in" (the official police ruling) which she became the sole survivor of. After her family was killed Ariadne spent most of her childhood at the Jeremy Hartwood Mental Hospital, where they tried desperately to figure out what was wrong with her. It is revealed that the Presence and the song influence had warped and twisted Ariadne's mind until she became a hollow shell of what she could have been and essentially an agent of the Presence as she was the reason both Berenice and Daniel was taken at the end of the game. She withheld the second music box from Daniel, which ultimately caused him to get taken by the Presence.
