Archwizard

The first archwizard was Ioulaum of Netheril, who achieved this status when he created the first flying city in Faerûn, Xinlenal, through the use of a mythallar, another of Ioulaum's creations. The moment Xinlenal was afloat, every Netherese arcanist of sufficient power strove to make their own. An archwizard was an arcane spellcaster, almost invariably a wizard, who had their own city with a mythallar. Today in 1479 DR, only Thultanthar has an archwizard who meets ancient Netheril's requirements.
