Description
is the ancient that rests upon the shelf across from us. It is being controlled and its life energies slowly being consumed by something immense beneath us.

There is a cave known as the Undershell down below L'ghorek. In that cave are three powerful ogre magi that are maintaining a ritual connecting the thing below with the ancient. You must kill these three to disconnect L'ghorek.

Rewards
You will receive:

Progress
You must slay each of those ogre magi to stop their rituals and disconnect L'ghorek from the one below.

Completion
Now that you have unplugged L'ghorek, we must attempt to make contact with it. I can sense that the ancient yet lives, but only barely.
