Felwood is a forest far north of the Barrens, even farther than Ashenvale. There, slimes are found all around pools of water blessed by the touch of Fel. The Scourge decimated the area with attacks of Infernals and other demonic magics--the slimes supposedly crept up through the earth during these attacks.
Gather samples of Felwood slimes and we will use the testing equipment next to me to create a control group for our tests against other samples you gather.
Ah, excellent. These samples will do nicely. I thank you for your help.
Once we've gathered all the samples of slimes, we'll be able to determine more. I am beginning to suspect that Lady Sylvanas' hunch was not only correct, but more insightful than even she could have predicted. These samples are very interesting. Just seeing how they've reacted with my compounds... hmm, yes, we'll definitely need to investigate further.
