Undead of Weaver's Present

Quest Giver:

While we're on the subject of things that frighten me half to death... By now you must have seen the grave diggers, sorceror hunters, and other such Gillgut wandering the graves of the abandoned villages around Weaver's Fen. They are rotting husks of people, with flesh grey and bloated with swampwater. Forgive me, I might retch just thinking about them....

Can you cull these fiends at Piscarian Fishery as well for my peace of mind?

Progress:

I cannot bare to go back to the places I am sending you, but I once roamed Weaver's Fen freely as you do. People used to thrive here before the illnesses spread across the swamp. One day people began to fall sick and it proved to be the beginning of the end for life here outside of the settlement. Even in the settlement we must be careful who we admit. You didn't sneeze just now, did you...?

Finish:

You've cleared out the ghosts to the west and the wretches to the south. Well done! I haven't had someone as reliable as you in ages. There is one more concern of mine close to the settlement I would like you to take care of.
