Speak with Zevrost in Orgrimmar's Cleft of Shadow.
I have just received word from Zevrost, Orgrimmar's foremost warlock trainer. He wishes you to travel to Orgrimmar and speak with him in the cleft of shadow. It sounds like he has an important mission for you.
You will also receive:
- 680 experience
- 4 20 (if completed at level 100)
- 10 reputation with Orgrimmar
