What would you do with your very own personal secret society?
One with influence over every government on the planet (including the military branches). And effective (covert) control over all the major media outlets, and hollywood (and bollywood), and all the education systems on the planet; and, of course, total unchallenged (and unaccountable) power over all the central banks in the world, and thus all the economies. Throw in command of the mafia and other organized crime, for good measure.
With you at the top as Uber Ultra Mega Grandmaster (or Grandmistress), of course. ie, directive power over all capabilities of the apparatus.
How would you exercise those capabilities? To what end? What would you want to cause in the world?
Me? I'd probably order that someone immediately go out and buy me some ice cream (and don't dawdle!). Probably cherry ice cream (oh indulgent me).
