Crook of Rao

The Crook of Rao is a fictional magical item of the Dungeons and Dragons Greyhawk campaign setting. Appearing as a shepherd's crook, the artifact has been in the possession of Canon Hazen of Veluna since 585 CY, when he aquired it from Drax of Rel Astra. The crook was used to remove most of the demons from the Flanaess in a ceremony performed by a select number of Oerth's most powerful clerics and magi in Coldeven of 586. The resulting even is known as the Flight of Fiends.
