Locked Up

Exploration Stage: Hall of Departure
From: Juliette
Description: Mon ami, the Huntress told me that the little demon entered the Manor. Poor thing! I think the Mistress could have grabbed him and locked him up in her basement... Alas, I can’t go down there. The Mistress is very meticulous about hiding the basement key. I’m afraid that only you can find it!
Completed: Mon ami, the key you found fit, and I checked the Manor’s basement. Our theory was correct: a gloomy little demon is sitting down there... I tried to release him, but some invisible force won’t let him go beyond the basement!
