Legendary knights & beautiful maidens like Lady Guinevere & Joan of Arc once existed from the 12th to the 15th century. To protect their kingdoms, most nobles and kings employed magicians like Merlin & fearless knights that were idealized in King Arthur's entourage of the Knights of the Round Table. Joan of Arc passed away in 1431.
When Leonardo da Vinci was between jobs in 1495, he laid down his paintbrush & became the Father of Engineering & fashioned weapons of war such as a robotic knight, a parachute, & impregnable fortresses like Warwick Castle. It has a hidden dismal dungeon & quarters for the brave armored knights and horses that accompanied them.
