Toxic Horrors

I've studied the sample you returned with, and while I can't say for sure, I believe it contains traces of toxic elements. However, the only way to know for sure is to gather some as a comparison.

I believe that the Deadwood furbolg may be gathering these elements from other corrupted creatures in Felwood; in particular, the elementals living in the Irontree Woods, called toxic horrors.

Collect a few samples for me to compare, but be careful -- it's very dangerous there!

I think we are beginning to uncover what is happening here, <name>.

I have to compare this to the substance you found in the cauldron, and then I'm sure we'll know more.
