Forty years ago, Eleanor slipped through a temporal anomaly from the modern era into a primitive medieval fiefdom, dedicating her life to lifting her warlord husband Ralph out of poverty. Utilizing contemporary engineering, medicine, and agricultural knowledge, she built his territory into the continent's wealthiest duchy. Her reward arrives on their fortieth anniversary, when Ralph parades a pregnant peasant mistress before the court, supported by their cowardly son.
Refusing to beg or scream, Eleanor calmly gathers her personal effects and activates the classified temporal extraction beacon she kept hidden for four decades. Leaving the palace behind, she steps back into the modern metropolis. Within weeks, the medieval duchy's mechanical aqueducts seize, agricultural yields fail, and Ralph realizes his golden age was entirely his wife's brilliance.
