Now it is time to capture the essence of the avatar of Hakkar.
Take the Egg of Hakkar to the Sanctum of the Fallen God in the Sunken Temple in Azeroth. Invoke the egg's power to stir the dead god.
He will send his minions against you. Defeat his bloodrinkers and take their Hakkari blood, then use the blood to dowse the eternal flames that hold Hakkar's spirit. When all the flames go out, the avatar of Hakkar will enter our world.
Defeat him, and place his essence within the egg of Hakkar.
The essence of Hakkar has been collected! Even now the Egg stirs with life! Could the myths of Hakkar be true?
That must not be true, for it is then I fear what Hakkar may do if birthed again. I will keep this egg safe and be sure it does not fall into evil hands.
Your labors with me are finished, <name>. You have touched a legend, and your actions may one day change the face of our world.
