De Sède and Plantard fell out over book royalties relating to "L'Or de Rennes" and never worked together again, at the same time Philippe de Chérisey announced the "parchments" were his creations that he later elaborated upon in his 1978 unpublished document entitled "L'Énigme de Rennes", claiming they were originally made for his friend Francis Blanche, as material for a French radio serial entitled "Signé Furax". The story about the parchments was previously given in the 1977 document by Jean Delaude entitled "Le Cercle d'Ulysse".
