Mysteries of the Desert - Mysteries of the desert, #1

In the 13th century, amid the dominion of the Mamluk Dynasty, a caravan consisting of ninety individuals, including merchants and common travellers, initiated their long challenging journey from Luxor to Cairo across the desert. Traditionally, this passage demanded a gruelling fourteen-days trek.  However, this caravan made an unconventional decision, opting for a shortcut route that promised to reduce their journey to only nine days, a considerable reduction from the standard duration.
Yet, this shortcut path has been banned for two hundred and sixty years, dating back to the rule of the Fatimid Dynasty in 10th century Egypt.  Despite countless narratives transmitted across generations in Egypt and its neighbouring cities, the precise occurrences that prompted the ban on this during that era remain elusive and shrouded in mystery. So, why did this particular caravan defy this long standing taboo and opt for this forbidden path? What is the history of this route? What happened in the 10th century so that the Fatimid Dynasty banned this route? Will the caravan safely cross the desert?  Caution: If you are an atheist, please don't purchase this book as it is not intended for you.
