Objectives
Collect 333 Shadowy Gems by looting Elementium Gem Clusters from creatures in the Dragon Soul Raid encounter.
 * Shadowy Gem (quest item) (333)

Description
The daggers I have given you are lifeless shells. They can do great things, once they are given a means to contain the power I have in mind.

I need for you to acquire Shadowy Gems for me. The facets of these unusual stones are like windows into the infinite. They are often used by minions of the Twilight's Hammer to control the most powerful of elementals.

A great battle is raging around Wyrmrest temple. Collect Elementium Gem Clusters from Deathwing's minions and bring the gems to me.

Rewards
You will receive:

Progress
How many gems have you collected?

Are my father´s minions as twisted as him?

Completion
Ah, do you see how they shimmer? Many fine gems sparkle in the light, but only these seem to sparkle with darkness.

I´ll perform an enchantment on these while you are on your next mission.

Are you ready?
