False exuberance.

Exploration Stage: Foggy Oasis
From: Mr. Black
Description: Thanks, I'm not comfortable with this atmosphere. It's covered in a misty vapor that makes me feel like I'm in heaven. I guess that's what makes me relax my guard. There seem to be several fog generators placed in this area. Let's check one of them and turn it off.
Completed: That's a nice aroma. It seems that the medicinal herb scent that filled the place was emanating from the fog generator that had just been turned off. Hmmm...I'd better check this out thoroughly. There might be a sleeping sickness-causing substance in it.
