The mysterious Cabalist whose machinations derailed the djinn entered medieval history as “Prester John,” the “priest and king over fifty kings” in Further Asia. The number 50 (a coded reference to certain ancient Sumerian magical traditions) and the Hermetic phraseology “priest and king” lead most Cabalistic scholars to assume that Prester John was a very ancient Egyptian magus who went into hiding during one of the ancient Cabal upheavals −− perhaps even during the rebellion of Khaibitu−na−Khonsu. His knowledge, power, and subtlety would be unmatched in that case −− and he might very well have discovered the coveted secret of immortality. (Prester John may also be the legendary Fisher King who guards the Grail.) Cabalists, usually of the wilder−eyed and scruffier breed, have sought Prester John ever since he announced his existence to Pope Eugene III in 1145. His domain could be anywhere “east of Suez” −− Ethiopia, Tibet, and Sumatra have all been considered potential starting places.
