Author/researcher Filip Coppens writes concerning the Société Périllos website:
FYI: The series on the devil inside the church of Rennes le Chateau is now completed. It is a 6 part installation, which I think is quite intriguing, as it in essence shows it is not Asmodeus at all…see here for the opening page.
Also available at the starting page listed are numerous other articles related to the Rennes le Chateau mystery, including a recently concluded series on ‘the cisterns’ of RlC. Thanks Filip.
