Vangerdahast is perhaps the greatest mage to have ever taken up the mantle of Mage Royal. For decades he controlled the Kingdom of Cormyr, in fact if not in title. While the king would fight the wars and sit on the throne, Vangerdahast would keep the court in order and keep control of the various factions who wished to dethrone the King. He was the overall leader of the defenses of Cormyr and only the king could command him. His title of Mage Royal allowed him control over the two main military factions of Cormyr, the knights known as the Purple Dragons and the mages and wizards of the War Wizards. He could also to a large extent control the Harpers who reside in the kingdom. He was trained by Elminster and therefore knows spells and magics far beyond the average wizard.
