"Bravo! You have bested the best. You need bend your knee to no one, man or woman."
―Chevalier d'Éon to Arno Dorian upon her defeat.[src]-[m]

Charles-Geneviève-Louis-Auguste-André-Timothée d'Éon de Beaumont (1728 – 1810), usually known as the Chevalier d'Éon, was a famous transgender French aristocrat, diplomat, spy, dueler and, during the Seven Years' War, a soldier in the French Army.


In a time where dressing up was popular, d'Éon first dressed as a woman at a costume ball, aided by her slight build. King Louis XV took notice of her, and realized that d'Éon's appearance of a beautiful woman would make her easy to deploy as a spy. She was soon sent on a mission to Russia in 1756, equipped with a farthingale and a cascade wig. D'Éon listened at doors and stole documents with great dexterity. For this, Louis decorated her with the Order of Saint Louis.[1]

After 49 years of dressing as a man on most occassions, d'Éon took to appearing publicly as a woman in 1777, sparking a debate on gender. When the Bastille was stormed in July 1789, she wrote to the National Assembly and offered to lead a division of female soldiers. However, this offer was rejected by the Assembly.[1]

D'Éon was known for being a skilled swordsman, and frequently challenged fencers to friendly duels, betting they could not defeat a woman. This practice proved to be profitable for her. Sometime during the French Revolution, she contacted the Assassin Arno Dorian.[2]

Upon meeting him, d'Éon told him not to be confused by her appearance. She then told Arno that she knew of his allegiance and that he needed her help. To prove that he was capable for the job, d'Éon asked the Assassin to challenge several swordsman to duels and defeat them. After Arno returned triumphant, d'Éon challenged him to a duel as a final test. After the Assassin won the duel, the latter congratulated him on being the best swordsman.[2]

D'Éon later requested Arno's help in investigating the Crimson Rose, suggesting he help the man so he could be allowed into the Crimson League.[3] Upon her discovery that the league's members were all Templars, d'Éon quickly alerted Arno to this fact, following which the Crimson Rose was assassinated.[4]
