Long before and far away, there lived a man with a dream. He dreamed building a magnificent marketplace in the middle of a Arabian desert. After a time, his dream city was built. The city walls were made by gold and covered with jewel. From far and near, traders went there to buy their fortunes. Yet one day the city suddenly disappeared, left no trace in the desert sands.
Does this city actually exist? Some people say it did exist. They point to a book of ancient folktales are called The 1,001 Tales of the Arabian Nights. Supposedly, some tales hold clues to its exactly location.
