Nisrin
From Tardis Wiki, the free Doctor Who reference
Nisrin was a Scandinavian slave who ran Lord Cassim's house and was in charge of the lower ranked slaves. She taught Amy the ways of an Arabic slave and the names of stars. Amy repaid her by teaching her new words when spying on Lord Cassim on Prince Omar's orders. After Lord Cassim was deposed she became the leader of the Harem. (AUDIO: The Destroyer of Delights)
