Dartol's Rod

I'm not completely certain what Teronis had in mind next, but if what he said was true about the rod's power, then it will allow you to take on another form altogether, presumably that of a furbolg. Perhaps he meant to use its powers to get closer to them, but even the uncorrupted creatures would slaughter him were he not careful. Transformed by the rod, Dartol would have to speak to a furbolg who was uncorrupted. I would start with one known as Krolg. Seek his hut southeast of Mystral Lake.
