The Axe of Earthly Sundering (quest)

Objectives
Slay 5 Sundered Emerald Colossi. Provided item: The Axe of Earthly Sundering
 * slain x5

Description
The emerald colossi are the greatest of the Stone Mother's creatures. They must be the first to be removed from the field.

I brought Stonefather Oremantle's axe for just this task. Use it to sunder the giants.

That should bring them down to a more manageable size so that you can finish them off.

Rewards
You will also receive:

Progress
We need more of those giants destroyed,.

Completion
Thank you,. Without their giants, Therazane's forces will have a harder time taking Stonehearth.

Now, if you please, hand back the axe. I'll keep it safe until you can rescue the Stonefather.
