The Vizier was a court official in the court of Lord Cassim in the 9th century. He arranged entertainment, such as belly dancers, darats and jugglers. He was strongly superstitious and religious. He went mad after the Djinni came to search for the Black Guardian in the castle. (AUDIO: The Destroyer of Delights)
