Knecht resigns as Magister Ludi, then drowns
Joseph Knecht rises from orphan scholarship boy to Magister Ludi, the highest office of Castalia's Glass Bead Game, then resigns in a formal letter warning the order that it is historically fragile and blind to the world that funds it. He leaves to tutor Tito, the son of his worldly friend Plinio Designori, and on his first morning he follows the boy into a cold mountain lake and drowns. The death is left ambiguous: a waste, or a sacrifice that marks Tito for life.
