The Grand Magister is the title traditionally held by the leader of the Thalassian Magisters. It is an extremely high and prestigious rank to hold in Quel'Thalas, above even the Ranger-General of Silvermoon. Like the Ranger-General, the Grand Magister is an elected position.

The individual bearers of the title style themselves as the "Grand Magister of Quel'Thalas." The title was once held by Grand Magister Belo'vir, a renowned magus who was elected several years before the Third War, who was slain during the Scourge Invasion of Quel'Thalas. Following the war and the rise of the Sin'dorei, Archmage Rommath became his successor. Under his leadership, the magisters retained their high political power in Thalassian society after the near-calamity.
