Sinan, Prince of Thieves, was the main character of a book wrote by Adira, the Caliph. Each story was told by the Great Storyteller, a mischiefmaker and prisoner of a powerful queen, was mitigating his sentence by telling the queen a different tale each nigkt. It became the third-most common manuscript in Medinaat al-Salaam. Many of Sinan's tales, including “Sinan and the Wise Men of the Cave,” “Sinan meets the Immortal Man of the Moon,” and, “Sinan and the Sultan of Hearts,” did not end with an obvious moral coda or happy ending like most of the other stories in the book. Sinan's stories told the history of the Old Man of the Mountain and his family of Assassins.
