The devil's maze or black maze?

I'm trying to gather some more research on some type of ancient ritual of a splinter free mason group. I've only ever heard one mention of them as "unis infinitas" or something like that. It's supposed to mean "one forever" in Latin... or "one world order".

The devil's maze was supposed to be a 21 layer ritual journey initiates took to earn the right to become part of this super-secret splinter group.

Two years ago, I found a site talking about this group, and hinting that this one group was the controlling force behind everything that occurs through the supernatural powers they gain as a result of passing all 21 tests of the devil's maze. But now I can't find the site.

I've run some searches and can't find what I'm looking for. I've tried

devil's maze
devils maze
devil's labyrinth
devils labyrinth
black maze
black labyrinth

(I found one reference to a black labyrinth some time ago).

Has anyone heard of this?

Does it still exist?
