Destroy 8 Diseased Wolves, and then return to Mulgris Deepriver at the Writhing Haunt, Western Plaguelands.
While there was little I could do alone to thwart the Scourge, I nevertheless came to these lands to try and heal the damage done to nature. Animals suffer from the plague that continues to choke these lands, unable to find mercy and peace. I ask for you to continue what I could not finish here.
There is no salvation for the suffering animals but a sweet and merciful release. Seek out diseased wolves nearby and put them down. Please [player], end their misery - doing so will surely soothe mine.
