I was wandering the zone looking for wolves for a Cleric of Mischief quest, and I finally found them. . .surrounding Gourdhead.
They were all barking at him, but not attacking. I killed them (each ignored me till I hit), along with a smattering of diseased rats and halfling skeletons. Looting the corpses, I counted 33 wolves.
Ended up with 6 black wolf skins, 20 regular skins (ruined/low q/med q), and enough wolf meat to make 30 filleted wolf meals. The cleric suddenly went from "Hello, young human! Could you help me?" to "I will do nothing to help you!", right after I gave him the items (which he kept).
BTW, later I saw 5 more wolves around him. I'm guessing they aggro on him when they wander close enough, but they can't target him to attack.
