Fully investigate the Blood Furnace and then report to Force Commander Danath Trollbane at Honor Hold in Hellfire Peninsula.
[class], put together a force to investigate the Blood Furnace inside Hellfire Citadel at once! And that means today, princess!
The magic we have at our disposal indicates that something unnatural is occurring in there. But something more powerful inside is blocking any detailed arcane investigations. It figures!
You can expect heavy resistance - no other mission that we've sent in there has yet to return!
Scout it entirely and then report back to the force commander with what you witness.
