Description
It became known to us in later days, as we were doing what we could ourselves to survive, that Isalien, a night elf priestess of our company, had gone to the night elvic ancestral city, now known as Dire Maul. From what we gathered, she went there both for personal reasons and also to unlock the secrets of the piece of the amulet that she had in her possession.

She didn't quite make it, though. Word got back to us that she was ambushed at the Shrine of Eldretharr by Alzzin the Wildshaper and his forces.

Rewards
Upon completion of this quest you will gain:
 * 11900 XP (or a compensation at level 80)

Progress
Surely you haven't already dealt with the salvation of Isalien's spirit and the retrieval of the right piece of Lord Valthalak's Amulet, ? Be sure to recombine the pieces of the amulet before handing it to me.

Completion
Thank you,, for putting Isalien's spirit to rest. Now, perhaps, she will find peace with her goddess. And, we have the reassembled amulet, as well! But we still have the hardest test ahead of us.

In order for the brazier to be attuned to calling forth Lord Valthalak, there are a few more items that need to be gathered and brought back to me here.
