Ualair the Silent was the last High Mage of Myth Drannor.
Ualair, in the last years of Myth Drannor, was the High Mage of the city and also the Master of the N'Vaelahr, the shadow army of Myth Drannor. At the start of the Weeping War he used a high magic spell to polymorph the gnome Rhymallos into a Mezzoloth so he could infiltrate the Army of Darkness as spy. The gnome sent invaluable information back to Ualair.
Tragedy hit Ualair when thank to Rhymallos' informations Malimshaer discovered the Vaults of Uvaeren, a deposit of important elven artifacts. Aulumpiter personally directed Rhymallos' regiment to went to Uvaeren to take the artifacts away. Immediately Rhymallos informed Ualair but can't gathered reinforcements in fear to unveil Rhymallos' cover. Rhymallos and Ualair fought the Army of Darkness' troops alone at Uvaeren until they decided to destroy access to the vault, dying in the process.
In truth however, Ualair survived, severely injured and entered stasis inside a tomb in Impiltur, where he also brought the comatose Rhymallos. In 1374 DR, Khelben Arunsun located and awakened them in order to gain their help in the raising of Rhymanthiin. Ualair and Khelben both gave their lives to fuel the Ritual of Myriad. Ualair's soul then went to Arvandor.
