Machinelike Sobbing

Exploration Stage: Musical Glade
From: Sophia
Description: Someone is trapped in this music box! When I found it, I wound it out of curiosity - but instead of music, I heard a mournful whisper! I was so horrified I dropped the key. Please, find it for me.
Completed: Thanks for finding the key! Can you hear the whispers coming from the music box? "He trapped me in here..." I also caught a name... Celeste, I think? It’s hard to make out. Let me wind it again. Now the whisper is pleading for help. This is not a recording!
