The wild boars who have settled in eastern Cardolan carry a deadly sickness.
'You there! You look strong and capable. I have a proposition for you, if you are interested in making some coin.
'East of here, a large number of wild boar have made dens. Usually I would not meddle with the creatures, but this lot are sickly and will attack on sight.
'Go to the boar dens and defeat as many of the creatures as you are able. Bring me back some of their meat as well. I have an idea for something that may help things.'
Merruth has asked you to hunt diseased boars in eastern Cardolan, and to place the meat along the route to the Warg dens nearby.
You should bring Merruth the diseased meat.
Merruth is in eastern Cardolan.
