The French monarchy faces an existential threat when King Philip IV, known as the Iron King, invokes a lethal curse by ordering the execution of the Knights Templar's Grand Master. Philip struggles to maintain control over a crumbling dynasty defined by weak heirs, scandalous marital infidelities, and the simmering resentment of his powerful subjects. As he attempts to consolidate his authority through cold, calculated governance, he finds himself trapped in a web of political maneuvering that extends far beyond his immediate control. The narrative unfolds through a third-person perspective that meticulously tracks the shifting loyalties and hidden agendas within the royal court.
