Speak to Ogtinc in Azshara.
Ogtinc of Azshara has sent out a call for seasoned hunters such as yourself. He is a furbolg hunter who has left his tribe to aid the Cenarion Circle. His teachings are meant to enrich the wisdom of others who share his craft, and guide them toward maintaining a balance. You would do well to speak with him.
Ogtinc resides atop the cliffs of Azshara, northeast from the Ruins of Eldarath.
