Jeanne d'Arc is the historical French warrior woman who fought for France during the Hundred Years' War. Executed by burning at the stake on May 30, 1431, after English condemnation as a witch, she manifests within the narrative as an apparition or ghostly vision. She appears primarily to Richard III, tormenting and haunting him by exploiting his psychological vulnerabilities and internal conflicts. Her presence intertwines with themes of persecution and perceived heresy, reinforcing the English view of her as a malevolent or demonic figure.

These ghostly appearances are visions targeting Richard's mental state, not physical interactions. She symbolizes the lingering consequences of being labeled a heretic and associated with witchcraft. These themes parallel Richard's own struggles with being perceived as demonic due to his intersex condition. Her hauntings contribute to Richard's psychological deterioration, casting her as a spectral antagonist embodying his fears and the societal stigma he faces.

Rooted in historical events, including her martyrdom and execution by burning, her role in this story is confined to her ghostly influence on Richard. She functions primarily as a symbolic and supernatural force, not an active participant in the main plot. There is no depiction of her life before death or development beyond this spectral presence.
