In theory, there were only 4 powers that truly ruled the world globally, and this was true but still, Viktor would add a fifth...
The Egoist Mystery, that power full of madmen who only fulfill their desires and no one knows much about them.
And this is the only power with so much expansion worldwide...
It was never known how they got members from all over the world, as this was very difficult with the lack of technology capable of making it useful to have members spread all over the world.
Basically, they should have nothing to offer people from another part of the planet, so no one from there would join. And they wouldn't have much to receive by having members from elsewhere either.
But the Egoist Mystery succeeded in becoming the only organization with a large worldwide expansion, having many members in other parts of the world.
