The Masked Mage is a figure of unknown name who acted boldly on the night the white and black hosts changed hands in Paris during the Fronde. He wore a mask and was not identified by those present.
His actions coincided with the arc of the forbidden books circulating through the Quartier Saint-Germain-des-Prés. This led some to speculate that he could be Marsilio Fountaine, who that season frequented the same forbidden circles. The shadow of Murmur pervades the events of that night.
