By 1422, King Henry V of England had died six years prior from dysentery and King Charles VI of France followed two months later. Six years after, the heir to France's throne was muddled with rumors spread by the English and Burgundians. Queen Isabeau of Bavaria was accused of affairs, making Charles VII's legitimacy to the throne questionable.
Jeanne d'Arc joined the conflict on the side of the French, armed with a Sword of Eden. When the Templars discovered this, they had her arrested and burned at the stake to acquire the artifact.
