The caravans can't get through the woods and the village is running low on supplies. It's that Dalish clan causing trouble again, I know it. I had my man speak to their "keeper" several months back and she (I think it was a she, you can't tell with these elves) said they'd leave for more remote parts. It looks as though they're back, likely their stupid landships blocking the roads. They're a stubborn race and more than a little dense!
I must trouble you for a favour. Go to the Wending Wood and order them to leave.
