Nine Turning Mirrors

The Grand Vizier of the Agatean Empire during the events of The Colour of Magic and Mort, and a typical example of Grand Viziers everywhere.

In The Colour of Magic, he asks the Patrician to see that Twoflower is killed and doesn't return to the Agatean Empire.

In Mort, he dies while trying to kill the Sun Emperor, after presumably previously killing the boy's father and grandfather. He is later replaced by Lord Hong, who is Grand Vizier by Interesting Times.
