The Zahir is ancestral lord of Castle Darkwater and was the last master of the group of rivergoing mercenaries known as Darkwater Deepers. He has been over the Aegis wall three times, served as Imperial Watermaster, been engaged to Mirabelle Vozhd-Kahar and Sahna Nillu at various times but married neither, taken the mark of a Mage of Fastheld, nearly died at the hands of Wildlings and human foes alike ... and somehow survived it all. As the snow ceased to fall in 628 ATA, Thayndor disappeared one day. One afternoon he was at Darkwater Keep, and the next -- gone.
