Since the accident, all Gnoarn thinks about or talks about is cleansing Gnomeregan of the trogg infestation and finding a cure for the sickness that plagues it, <name>.
Luckily, Razzle and I are close to some kind of cure - either that or the recipe for a really powerful rum. We won't know until we test! Naturally, in order to test our theory, we're going to need a few things; namely, fallout from the irradiated troggs in Gnomeregan. Fill up this phial with the green glow and bring it back!
