Giving the lifeless form of Vazruden the Herald the once-over, you discover a rolled letter, its seal yet unbroken. An elaborate "I" is pressed within the blood-red ink. Cracking the note open, the message that you read is most disturbing.
Nazgrel back in Thrallmar will definitely want to take a look at this!
What is that letter you have there, <class>?
It's signed by Illidan you say?! Let me have that.
<Nazgrel reads the letter, and then again a second time, thinking a moment before going on.>
This news that you bring is ominous indeed. Knowing this, we must accelerate our plans against Hellfire Citadel and this Blood Furnace. Because you have shown that you can get the job done, I want you to head up those plans!
Centurion Caza'rez will give you your next mission, though I suspect it will be far deadlier than your first.
Lok'tar ogar, <name>!
