Description
The Duke of Orléans is a significant antagonist early in the story, introduced as a cousin to King Louis XVI and a prince of the blood royal. As the second in line to the throne of France, he holds a position of high status and privilege, yet this proximity to power is precisely what fuels his central conflict.

A scheming and manipulative individual, the Duke of Orléans is driven by a deep-seated ambition to usurp the throne. His primary motivation is to eliminate King Louis XVI and secure the crown for himself. To achieve this goal, he engages in various plots and conspiracies throughout the narrative. When his plans fail, he is quick to shift the blame onto others or have them killed, all while maintaining a public facade of loyalty to the royal family and his country.

In the beginning, the Duke of Orléans acts as a mastermind of intricate plots against the royal couple. He is the architect behind a scheme to kidnap Marie Antoinette before she could marry the then-crown prince, a plan that is ultimately thwarted by Lady Oscar. Following this failure, he attempts to assassinate Prince Louis XVI by tampering with a hunting rifle, rigging it to explode upon being fired.

Later in the story, his role evolves. The Duke of Orléans, influenced by his own liberal ideas, allows anti-monarchist figures and revolutionaries to secretly gather at his Palais Royal. He notably provides aid to Jeanne de Valois-Saint-Rémy, the mastermind behind the Affair of the Diamond Necklace, helping her escape from prison and covering the expenses to publish her scandalous memoirs, which were designed to damage the Queen's reputation.

His key relationships are primarily strategic and self-serving. He temporarily forms a partnership with Madame Du Barry, the mistress of the late King Louis XV, to work against the new king and queen. However, when King Louis XV is dying and it becomes clear that Du Barry will lose all her power, the Duke of Orléans immediately abandons her without hesitation. The Duke does not possess any notable physical or martial abilities; his power lies in his political cunning, wealth, and his ability to manipulate events and people from the shadows.

Throughout the story, the Duke of Orléans remains largely static in his goals, consistently pursuing his ambition for the throne. His development is less of a personal change and more a shift in his methods, moving from direct assassination attempts to supporting the emerging revolutionary forces as a tool to weaken the monarchy. His importance in the narrative decreases significantly in the latter half of the story.
