Wounded Ancients

Objectives
Bring a piece of Corroded Shrapnel to Kaela Shadowspear in Stonetalon.
 * Corroded Shrapnel

Description
It seems obvious to me that the protectors of the Vale—the treants—had something to do with the Venture Co. being driven back. Unfortunately, even those once great guardians have now become corrupt. Gaxim thinks their corruption is somehow linked to the weapons the goblins used during their retreat. I told him I'd collect a sample from a wounded treant and allow him to study it in order to figure out if that's true. Bring me some of the shrapnel so the gnome can tell me more...

Reward
You will receive:

Progress
I have a feeling Gaxim will find a use for the shrapnel regardless of how the Venture Co. has used it in the past.

Completion
Thank you,. This should be more than sufficient for Gaxim to figure out how the treants were corrupted. I shall give this to him right away.

Gains
Upon completion of this quest you will gain:
 * 2300 XP (or at level 70)
 * 250 reputation with Darnassus
