The Pipeweed Pouch artifact can be found at Núrnen Fishery, in the north-western part of Sea of Núrnen.
Pipeweed Pouch, Spider's Venom Sac, Third Age, Circa 2941
The pleasant smell of Pipeweed emanates from this oversized pouch. The owner of this pouch harvested both the leaves and flowers of the Pipeweed plant in equal measure; the leaves are commonly dried and smoked in pipes and the flowers chewed to create a potent narcotic. As for the pouch itself, it appears to have come from the poison sac of an Ungol.
"Careful with the pouch, Torvin! It almost went in the fire.
Bah, that old thing. Time to get rid of that rag. Barely keeps the Pipeweed dry.
It is a rag, brother… and I'll keep this souvenir from our first hunt till it turns to dust. Remember us tracking that Great Spider through Mirkwood nearly sixty years ago - then drawing her out using live bait.
Yes, but, why do I always have to be the bait?
You have a quality. You make things want to kill you. It's a gift really.
But Torvin, this was your first kill. Ours together. It's what made you a hunter. And I'll treasure it always, brother!"
