Maria is one of the most powerful witches of the Hundred Years' War, and she hates the war itself. From a hilltop over the French countryside, she uses her magic to sabotage the armies fighting nearby and keep her village untouched. Heaven intervenes, forbidding her from casting spells where ordinary people can see, and setting a cruel condition on the rest of her power: the moment Maria loses her virginity, she loses her magic too. She keeps meddling in the war anyway, daring Heaven to make good on the threat.
