Hints of a New Plague?

Hail, and well met, <name>. I lead a group of adventurers investigating odd happenings in this area. My cousin in Hillsbrad recently put down his dog Stanley because the animal mystically grew to an immense size and savagely attacked anyone who came near him. I believe the undead are involved, and we're looking for signs to prove as much. Two of my companions, Quae and Kinelory, headed to the Go'Shek Farm in the Arathi Highlands, and haven't checked in for days. Find them for me? I grow concerned.
