 * Brazier of Beckoning (Mor Grayhoof) (Provided)

Description
My friend, Mor Grayhoof, was the first to fall victim to possession of a piece of Lord Valthalak's Amulet, and the corrupting spirit fragment that it contains. After stealing Valthalak's spellbook and amulet, we fled for our lives from the upper portion of Blackrock Spire. Along the way, Mor fell into the lower portion of the spire.

Later, we discovered that he survived the fall, only to be captured and tortured by War Master Voone. A few spectral assassins snuck in and slew him right in front of Voone.

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

Progress
Then it is done? You have retrieved the right piece of Lord Valthalak's Amulet, recombined the amulet into one whole, and finally put to rest the spirit of my old companion, Mor Grayhoof?

Completion
Thank you for helping Mor Grayhoof,. Another spirit rests in peace, and we now have the reassembled amulet! 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.
