Worgen in the Woods - Part 5?:

Kill 12 Nightbane Dark Runner worgen for Calor in Darkshire.

Calor: You might have noticed some larger worgen wandering around with the Shadow Weavers in the woods? From what we can tell, these Dark Runners make up the bulk of the worgen numbers.

On my rangings, I've also noticed that they have overrun the Rotting Orchard southwest of town. These worgen are a bit tougher than the last you faced.

Be on your guard.

Calor: Old Blanchy is on her last leg. Did you happen to find any oats for her?

Calor: You performed well against the Dark Runners, Yohaan. But it seems as though their numbers are inexhaustible. Every time we make progress, more spring up to refill their ranks.

What is the evil power that draws them here? Why have they come to disturb our unhappy realm...

I will put my faith in Master Carevin. No doubt he will get to the bottom of the problem.
