At the ford of the river Tevyn, the heavy and cumbersome cauldron sinks into the riverbed. Ellidyr arrives and offers to help extricate the cauldron if the others will credit him for the whole enterprise. Taran agrees, but Ellidyr reneges on their bargain and rides off with the cauldron alone when they have freed it. The companions then encounter Morgant and his army. In Morgant's camp they see Ellidyr beaten and bound and realize Morgant has betrayed them, seeking to claim the cauldron for his own and generate his own army of Cauldron-Born with which to conquer Prydain. Morgant offers to spare the companions' lives if Taran will enter his personal service. Doli arrives invisibly and cuts the companions' bonds. Mortally wounded, Ellidyr rushes the cauldron while Taran and the others engage Morgant and forces himself inside, destroying the cauldron. Gwydion, King Smoit, and his army arrive and defeat Morgant in battle. As Taran, Eilonwy, and Gurgi take leave of Gwydion at the verge of Caer Dallben, Gwydion observes that Ellidyr has, in death, found the honor he so dearly sought in life.
