Ioasaph grows up sealed inside a pleasure-palace built to keep him ignorant of suffering, yet the sight of human misery cracks his world open and sends him searching for a faith worth dying for. His conversion sets him against his own father, King Abenner, turning the throne room into a battlefield of love and conscience. When Barlaam finally departs, Ioasaph must decide whether to inherit a kingdom or follow his teacher into the desert — a choice that defines everything the story is reaching toward.
