How do you get 8 rival mages in a game

[Byeohazard]

I set the world for huge and cylindrical with 6 other worlds and max difficulty. I see the VI VII and VIII choices for the other mages but they are greyed out. How would I get those slots to function?

Maptype also matters, I think Great Land supports more than Islands or Continents... that said, I think I never figured out how to get VIII activated, had 7 at the most...

Thankyou cryptc. I will explore more and try that other map type.

Extra Large Great Land allows 8 AI.
