Vizeran DeVir

Vizeran DeVir was an exiled drow archmage during the Rage of Demons and is the mastermind of Elemental Evil Crisis.

History
A scion of House DeVir, Vizeran studied the arcane arts at the same time as Gromph Baenre. Gromph discovered Vizeran's true devotion to the Elder Elemental Eye and engineered his disgrace and exile as an unbeliever of Lolth. Ironically, this spared Vizeran from the downfall of House DeVir at the hands of House Do'Urden.

In his exile, he became a great archmage, building his tower of Araj and plotting his revenge. Centuries before the late 15th century DR, Vizeran DeVir crafted the weapons Ironfang, Drown, Windvane, and Tinderstike for the Elemental Evil cults in the Fane of the Eye of Tyar-Besil.

From afar, Vizeran acted as the shadowy patron of the Council of Spiders and from their number he gained the assistance of Grin Ousstyl.

During the Rage of Demons, Vizeran correctly deduced what had truly happened: Lolth had manipulated Gromph as a pawn to unleash the demon lords throughout the Underdark in order to gain absolute power in the Abyss. The demon lords in the Realms used faerzress to spread their madness. Vizeran devised a plan to send the demon lords back.

Therefore, at Gravenhollow, he approached an expedition led by some adventurers, hired by Bruenor Battlehammer to investigate the threat of the demon lords, offering his help. In truth, his plot aimed to gather all the demon lords back at their original place of summoning—Menzoberranzan itself—before they were sent back to the Abyss.
