Trouble at the Sludge Fields

Objectives
Report to at the Sludge Fields in Hillsbrad Foothills.

Description
Warden Stillwater, over at the Sludge Fields, north of here, has sent out a distress signal. The missive wasn't clear, but from what I could make of the letter there's a riot happening at the Sludge Fields and most of the guards have been killed. The warden has warned that any would-be-heroes approach from the back entry, located on the western side of the Sludge Fields.

He's also asked for discretion. He doesn't want news of this little *ahem* uprising to the surface.

Completion
Who are you? Did Sylvanas send you? Everything is FINE! Yes, perfectly fine! I've got it all under control!

Well, fine all things considered that is... We've got a few problems that perhaps you could help with,.
