Jean de Metz, also known as Jean de Nouillonpont, (born c. 1398) was a French nobleman and Assassin active during the Hundred Years' War. He was a companion of the French hero and Catholic saint Joan of Arc and was responsible for training the maiden and her cousin Gabriel Laxart.
De Metz was the squire of Vacouleurs' captain Robert de Baudricourt. At some point in January 1429, he heard about a young woman seeking an audience with his lord. Curious, he decided to meet the maiden, Jeanne d'Arc, and her companion Gabriel Laxart.
Knowing the dangers of travels, especially by women, during times of war, he discourage Joan's request for a journey to Chinon. As Joan's determination released her precursor abilities to persuade people with her radiance, de Metz, who could see with his Eagle Vision, realized that Joan was the maiden of prophecy. Realizing her role in the Hundred Years' War and the Assassin-Templar War, he bent his knee and swore to protect her.
