He eventually found his father, but in truth it was Markal, who bound his life to the Ring of the Unrepentant. He thought by the text Narxes found his father was still alive.
He went to the place where Cyrus, his father died. Zehir used the Heart of the Griffin to come to Sheogh, and with the help of his allies, defeated Kha-Beleth and saved the Queen. When the Queen was defeated, Zehir's ritual was disrupted by Biara. Afterwards, they met Raelag and Shadya on their way to the Queen. Zehir came to the Holy Griffin Empire and, with help of Godric Unicorn and Findan, killed Markal and avenged his father's death. When Zehir captured Al Safir and defeated the Necromancers, an Elf named Gallan from Irollan came to him with news - Queen Isabel would give birth to a Demon Messiah unless Zehir intervened. When Markal defeated the Leauge of the Silver Cities and killed Cyrus himself, Zehir went into hiding until the necromancers' power diminished enough to banish them away. Zehir is the son of Archmage Cyrus and Nadia. He chose to master elemental magic, figuring (correctly) that if he could control beings as fickle and powerful as elementals he would be well prepared for any magical struggle.Though the title First of the Circle was granted to the young Mage in the hopes of staving off political infighting during a crisis, the other wizards of the Circle quickly realized that it was only a matter of time before Zehir's skills surpassed theirs - time that is more likely to be measured in months than in years.
Excitable, headstrong, and energetic are the sorts of words the older Mages use to describe Zehir.
