When you return
Greetings once again, ‹name›! Our need for runecloth is constant, and we can always use additional resources if you are willing to part with them. For an additional stack of twenty runecloth, I will make sure that you are recognized for your continuing efforts on behalf of the Undercity.
Whenever you are ready to hand in the stack of runecloth, I'll accept it.
On completion
‹name› - without heroes like you working on behalf of the Forsaken, we'd surely suffer. Thank you for your continued efforts!
