The Cult of the Damned has not come just to extract power from dead dragons. I suspect I know what they are up to, but I need you to prove me correct.
I will grant you the guise of this dead necrolyte. Proceed to the back of the cave and confirm their intentions for being in this sacred place. I will watch through your eyes.
Be cautious, <name>, any damage done to you is likely to break the fragile illusion.
Rewards
You will receive: 5 60
Progress
I tire of this pestilence.
Completion
We are the Black Dragonflight. We have rained destruction on the lands of Azeroth for thousands of years. The decrepit Cult of the Damned worships death and we shall be glad to oblige.
Notes
If you need a new costume... "One of the cultists seems to have stumbled onto my blade and died... can I have a new disguise? I promise that I will be more careful this time."
Serinar says: As long as you don't go hacking and slashing your way through, they'll never know the difference.
Serinar's Presence whispers: It appears they are using those runes to deposit some of the power they've drained.
Serinar's Presence whispers: I had hoped my suspicions were incorrect... they're resurrecting magmawyrms. Come back to me immediately, it is time to purge this place of the Cult.
