Gates of Eberron
A changeling monk. Exiled from his monastery for reasons he's never understood, he travels the land seeking serenity and absolution.
Some years prior to the formation of the Oathbearer League, Zhao was visited by Hurak, the high abbot of the monastery, who informed Zhao that he had selected him for a mission to the Five Kingdoms. Zhao was to remain with humans indefinitely, ostensibly until he was summoned home to act as a cultural instructor to his people.
Eventually, while traveling with mercenaries, Zhao met Alex Knight and agreed to join his quest to slay Mordain.
