Khadgar (Ben Schnetzer)

Khadgar is one of the most powerful mages to have ever lived. He was the apprentice for the Last Guardian, Medivh, and went on to become one of the greatest heroes of the Alliance during the Second War and as a commander of the Alliance Expedition to Draenor.

His name means "trust" in Dwarven. This gave him an odd dichotomy with Medivh, whose name means "keeper of secrets" in Thalassian.
