Prieure de Sion
This Secret Society was devoted to "Occult and " Esoteric" interests.
One of the biggest Illuminati kingpins, and leader (Grand Master) of the Prieure de Sion was Frenchman Claude Debussy (bn.1862). Claude Debussy, a Merovingian, was Nautonnie (Navigator-helmsman) of the Prieure de Sion from 1885-1918. (See the document Dossiers secrets, planche no. 4, Ordre de Sion, written about in Holy Blood, Holy Grail.)
In 1891, when some secret coded parchments (Merovingian documents) were found by a French clergyman Sauniere, he was directed by church officials to visit with Emile Hoffet, an occult acquaintance of Debussy. Debussy was close friends with many of the top French occultists of his time. He is known to have been a close friend to both the notorious Satanists Jules Bois and MacGregor Mathers. Mathers started the Order of the Golden Dawn. Debussy was also a friend of the infamous Papus (aka Dr. Gerard Encausse) and W.B. Yeats. Papus was one of the men who during his lifetime was part of the interlocking occult directorate of occult groups.
