"The tale of Francoise Athenais, Marquise de Montespan, the witty and beautiful mistress of King Louis XIV. Madame de Montespan reigned as the King's Favorite for over a decade and bore the sovereign seven children. But she was also an arrogant and priggish aristocrat who did not take well to her royal lover's wandering eye falling upon younger and more attractive competitors for the King's affections. Madame de Montespan, once she had fallen out of favor with the libidinous King, is believed to have taken matters into her own hands to remove the obstacles to her desires, that of a triumphant return to the royal boudoir, through the use of magical love philtres and, eventually, poisons."
