Tale of Poison

You haven't been hit with the blade of one of them Savage Orcs have you? Well that's good to hear, those green sacks of filth in particular like to poison their blades with ichors from tails of Wyverns. Greenskins have put more than a few Dwarfs under the earth with the help of that poison. I've got a mind to send you out to collect Wyvern venom sacs if you're willing. That wizard fellow from the Empire says he can whip up a cure to the venom but he'll need quite a few sacs to work with or some such.

Head east into the Poisonwing Canyon and find the adult Poisonwing Wyverns. Slay ten of them for their full-sized venom sacs and then bring them back to Vingaard Proudhammer at Gav's Oathbearers.
