Future Primals and potential implementation into lore.

[Eloah]

Madeen/Maduin 'cause it'd be cool or something really esoteric like Seraph, Quetzalli, Remora, or Quetzalcoatl. They could also throw a curveball and use Anima.

I would love to see Madeen added into the game. Lakshmi was a nice touch, but we need more female beast-like primals. She can even be the primal for the Mombas from 8.

Also Madeen and Maduin aren't the same summon. They have different names, and I don't just mean in English, they are different in Japanese too. Plus Madeen is a female lion with wings and Maduin is a humanoid demon with horns. They might of started out as the same concept, but are different now.

And I say Madeen over Maduin cause, one, more female primals, and two, Maduins concept of played out.
