Enshrouded within the annals of French history, a tale of unimaginable horror and perversion emerges. It is the story of Gilles de Rais, an aristocratic warrior revered as one of France's wealthiest and most respected men, and known as a close companion to none other than Joan of Arc herself on the battlefield. Yet, beyond the chivalrous façade, he devolved into a monstrous serial killer, acquiring the macabre moniker of Bluebeard. His horrifyingly extensive record of bizarre sexual rituals, ghastly mutilations, and the cold-blooded murder of hundreds of children stands in stark contrast to his celebrated military career.

This chilling transformation begs the question - how could such a fall from grace occur? How could a figure as eminent as Baron Gilles de Rais, a Marshal of France, a luminous intellectual, and a paragon of the high medieval prince whose talents and accomplishments echoed those of the Renaissance, descend into such extreme depravity?

The explanations remain elusive and mired in speculation. However, historical evidence strongly suggests that de Rais, like many a returning soldier, bore the invisible wounds of severe Post-Traumatic Stress Disorder (PTSD). It's conceivable that the psychological aftermath of war might have ignited his latent psychopathy, pulling him into a vortex of violence and insanity.

His journey from celebrated hero to infamous monster is a chilling testament to the cruel and corrosive power of war. It adds credence to the notion that warfare's inhumanity has the potential to radically alter even the most heroic of individuals, transforming them beyond recognition. The tale of Gilles de Rais's descent into madness serves as a disconcerting reminder of the darkness lurking within the human psyche, ready to surface under the right (or wrong) circumstances.
