“Apethecary Zelana has been studying the beasts of Hellfire Peninsula in the field. She wants a sample of the blood you gathered; with luck, she might discover what turned those Bonechewer freaks' skins red!
Zelana is at Reaver's Fall, southeast of Thrallmar. Follow the road east and when you see a destroyed, green-glowing hunk of metal, you're there. She has a camp set up behind the wyverns.”
