A Call from Another World

Exploration Stage: Ballet Academy
From: Isabelle
Description: We need to know how Juliette escaped from the "ballet academy." She remembers the night she woke up to a strange sound. Something whispering, something calling to her...she saw an anomaly on the wall of this "academy". Maybe that's what's making that noise. Look for it.
Completed: You found the "disc-shaped music box." My anomaly sensor is going off when I go near this place. This disc-shaped music box is cursed. The curse is affecting the sound coming out of it.
