Omar (The Destroyer of Delights)

Prince Omar was the son of Lord Cassim, the 9th century Earth identity of the Black Guardian. He was worried when his father hadn't paid his taxes for two years. He sent Amy and Nisrin to spy on his father. Lord Cassim sent Omar to his death to kill the Legate of the Caliph, but he was saved by the Fifth Doctor. When the Djinni's ship destroyed itself, Nisrin had to stop him being killed by falling shrapnel. (AUDIO: The Destroyer of Delights)
