Bring 10 Webwood Venom Sacs to Gilshalan Windwalker at Aldrassil.
I came to Shadowglen to observe the webwood spiders that dwell in the Shadowthread Cave. They are cousin to a much smaller variety of spider; I believe the world tree has had a profound effect on them, and I would like specimens to study to confirm this.
First, I would like some of their venom. Gather Webwood venom sacs from the spiders in and around the Shadowthread Cave, to the north. I can then examine them for similarities with their smaller cousin's venom.
