Gestaniius

Gestaniius was a blue dragon and one of Tiamat's chosen.

History
He was invested with a third of Tiamat's divine power during the Time of Troubles but was devoured, along with Skuthosiin by the bearer of another third, Tchazzar.

During the Dracorage, he was resurrected by Tiamat and sent to the Dragonsword Mountains to create an army for Tchazzar, who was now his ally.

In 1479 DR, Gestaniius was attacking High Imaskar and at the same time was involved in the dragon game of Xorvintaal, allied with the mercury dragon Praxasalandos. His attack was repelled by the Brotherhood of the Griffon and he was killed by the paladin Medrash.
