Obtain the second part of Legacy of the Masters from Hareem Helheim.
<name>... You've heard correctly. Warchief Garrosh tasked me with tracking down this Council of the Black Harvest.
Unfortunately, I have heard word that the Alliance is ahead of us. I heard that some Human Warlock by the name of Hareem Helheim has information which will help us locate them.
Head to Lion's Landing, infiltrate their base and obtain the documents before Helheim's courier departs. Show Helheim no mercy.
