It's hard to say what's going on just looking at these dead skin samples. You did a great job recovering them, but I'm afraid I'm going to need live test subjects. Some of the miasma, fortunately, have developed docile qualities. I'm going to give you this vial of pheremones we extracted from the skin cells you brought back. I'm hoping that they'll follow the smell and you'll be able to lead them right back to me.
When you get back just take them down to H.P. Miles and the testing will commence.
