vessel for one's soul

Exploration Stage: Crystals
From: Isabelle
Description: I have heard that if you don't want your soul to be stolen, you can pull it out of your body and put it in something. Maybe Madame Dirichlet used this method to prevent the devil from stealing her soul? Can you help me find a container for my soul?
Completed: I guess from this circular section, madam tried to put her soul here. But since she didn't have mystical powers and didn't have much time ......, she had to give up.
