Haalrun at Telredor wants you to bring him 8 Diaphanous Wings from any of the firefly species in Zangarmarsh.
Living in such a remote location has taught us to make use of everything available. Of course, you have to learn to stop thinking about where some of these materials come from first.
I've found that the wings of the umbraglow stingers are very helpful for waterproofing. They're strong, thin, and flexible.
I see the look on your face. Like I said, it takes time to get used to the idea. If you're going to be out and about, would you mind bringing me some of the wings?
