Speak with Ureda in Orgrimmar's Cleft of Shadow.
I just received a scroll for you from Orgrimmar, <name>. It's from Ureda, one of the mage trainers there. She wants you to meet with her in Orgrimmar's Cleft of Shadow next time you're in the city.
You will also receive:
- 60 (if completed at level 120)
- 10 reputation with Orgrimmar
