Webwood Egg is an Alliance only quest in Shadowglen, the night elf starting area. In this quest, players venture into the Shadowthread Cave in northwestern Shadowglen to obtain a spider egg for Gilshalan Windwalker.
Now that I have the spiders' venom, I'd like some live specimens to study. Unfortunately, capturing a living, giant spider is more than I can ask of you, young <class>. And a giant spider is more than I could handle myself!
But if you can find an unhatched egg, then delivering specimens will be much easier, and I can then arrange for the unhatched spiders to be contained.
There must be a nest deep in the Shadowthread Cave. Please, search for an egg in the nest and return it to me.
Have you been inside the Shadowthread Cave, <name>? Did you find a spider egg?
Ah, very good. I will have this egg and the venom transported to Darnassus, then return there when my studies are done here. I expect to find out a great deal from these specimens, <name>. You have been a great help to me.
