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.

Progress
Surely you haven't already dealt with the salvation of Isalien's spirit and the retrieval of the Left Piece of Lord Valthalak's Amulet, ?

Completion
Thank you,, for putting Isalien's spirit to rest. Now, perhaps, she will find peace with her goddess. But, there is still a great deal of work ahead of us if we are to get out of this fine pickle we find ourselves in.

Unfortunately, I do not know the location of the one who died with the right piece of the amulet in their possession. But do not fear; in life I was a dabbler in the art of divination, so I have another task for you, which is going to enable us to ferret out the final piece.

Gains
Upon completion of this quest you will gain:
 * 15800 XP (or a compensation at level 80)
