Almighty ecstasy

Exploration Stage: Rapture Theater
From: Cardsharp
Description: Apparently Mr. N. can somehow manipulate people's consciousness! The actors on stage are all people who've gone missing in the city of shadows. When they enter the play, they completely become the characters in the play and forget their own pasts. The detective, how pathetic! I have to find the key to the last mask that will open Mr. N's diary. I see the winning mask is in one of the chairs. Bring it to me.
Completed: I can feel the power of ecstasy coming from your winning mask. I have a note. You can do anything. I can stop the stage from moving, I can stop the actors from moving, I can retell the story in a completely different way, I can change the nuances of the play... I am omnipotent!" I guess this is Mr. N's idea of happiness!
