In the shadowy corridors of medieval France, Pestilence, once a mortal known as Dr. Ambroise Leclerc, emerges as a figure cloaked in enigma and dread. As a Horseman of the Apocalypse, he is the embodiment of disease and decay, a sinister force once constrained to a mere quarter of his true, nightmarish potential. Currently, he stands as the most formidable amongst his brethren, a master of deception and malevolence. Masquerading as a healer, this dark alchemist weaves his knowledge into a tapestry of plague and pestilence, clandestinely orchestrating the downfall of mankind. His mission: to usher in the apocalypse, to set the stage for a world teetering on the brink of its inexorable demise.
