mind manipulation and suggestion is their "magick".
This is as old as their initiation ceremonies to the mysteries.
and the symbol is, how conveniently, the Fleur-de-lis lily flower, as well as the circle (the oroborus). the circle representing the rebirth cycle, or metaphorically the enlightening cycle of the initiate to the ancient mystery religion, with each degree the adept is "perfected" over and over again.
the beehive is an ancient symbol of the mysteries. I think it represents the "natural order" of sheep feeding the rulers, each bee knows it's place, a perfect caste system.
The Fleur-de-lis imo represents the trinity of the osirian cycle (isis osiris horus), probably there are other meanings as well.
