it's a good story..
sort of like Priory of Sion, exists.. but exists only as a joke...
made by some dude, Plantard..
then some other whacko came up with Holy Blood Holy Grail, saying
that the Priory of Sion was the organisation of descendent of
Christ..
Plantard panicked and confessed that it was all a hoax...
every other lane and branch is taken apart simply by asking
questions and doing basic investigation
