Check in Gadgetzan for Alchemist Pestlezugg and his analysis of the insect parts.
I'm going to spend some time taking a look at Scrimshank's surveying gear... as well as putting his personal effects in order. I get the sneaking feeling behind my ears that this isn't the last loss we'll be facing against these bugs.
I'd like for you to check in with Alchemist Pestlezugg to see if he has had a chance to process the insect parts we sent him. If they're ready, bring them to me.
Yes, I have the results right here. They are... unsettling, to say the least
Our initial suspicion that the bugs are being controlled by an outside force, we believe, is correct. If this is the case, then we are dealing with not only a very powerful unknown force, but also a malignant one. These bugs have been changed to be pure ravagers. I've never seen anything quite like it.
