Perceforest eventually regains his powers and, as king of Britain, creates a chivalric society. Specifically, he founds the "Franc Palais" of free equals with the best knights, paralleling the Round Table. "Thus the romance would trace back the model of ideal civilization that it proposes, a model also for the orders of chivalry created from the 14th century onwards, to a legendary origin where the glory of Alexander is united with the fame of Arthur." King Perceforest also abandons polytheism in favor of a monotheistic god and, under the influence of the hermit Dardanon, advances a new religion that will serve as a transition toward Arthurian Christianity. Meanwhile, Perceforest's knights, often with the help of a guardian spirit named Zephir, engage in heroic and romantic acts of derring-do in Britain as well as in the Low Countries. Tragedy comes to prevail as Perceforest's eldest son becomes infatuated with a Roman girl, whose treachery enables Julius Caesar to launch an invasion in which Perceforest and all his forces are annihilated and the kingdom is utterly destroyed.
