Ahune, the Frost Lord

Objectives
Travel to the Slave Pens in Coilfang Reservoir within Zangarmarsh and speak with Numa Cloudsister.

Description
I believe you are strong enough for the ultimate task set before us.

We cannot allow the plot between the Twilight Cult and the naga heretics of Neptulon to come to fruition. For the sake of Azeroth and all life upon it, we must act. Our path is clear. You must journey to the slave pens deep within Coilfang Reservoir and meet with our shaman there. Go, and quickly!

Completion
Thank the spirits you're here! We must summon Ahune quickly before it's too late...
