"Sacrifice. To the young it means to change, but to the wizened it heralds an end. I know both meanings better than anyone else."

Khadgar is perhaps the most accomplished of all living wizards and one of the most powerful magi in Azerothian history. Khadgar currently acts as the leader of the Kirin Tor. He was an apprentice to the Guardian Medivh, until he helped defeat his possessed master. 

While a hero of the Alliance, Khadgar is willing to work with the Horde for the good of Azeroth.
