This quest is not available in game.
Recover all three gems and a power source for the necklace from Uldaman, and then bring them to Jarkal Mossmeld in Kargath. Jarkal believes a power source might be found on the strongest construct present in Uldaman.
From the journal, you know...
* The ruby has been stashed in a barricaded Shadowforge area.
* The topaz has been hidden in an urn in one of the Trogg areas, near some Alliance dwarves.
* The sapphire has been claimed by Grimlok, the trogg leader.
- Shattered Necklace Ruby
- Shattered Necklace Sapphire
- Shattered Necklace Topaz
- Shattered Necklace Power Source
- Bloodstained Journal (Provided)
Here is the journal, translated for you to read on your own. The crux of it says dwarves hid the ruby, the troggs hid the topaz, and a trogg named Grimlok has the sapphire.
Look - you're going to need a power source to make the necklace work again. Dran Droffers doesn't know this. To find one, here's what I'd do: go as deep as you can in Uldaman and kill whatever construct there is the strongest. No doubt whatever that is would have it.
When you have everything collected, come back here!
