So, the Fractal Continuum (spoilers)

Binding coils, like the ones on poor Tiamat.

I have a feeling that it's probably not a Binding Coil, simply due to the fact that they're petrified, unless they were somehow able to perfect the binding coil method and used an advance method to seal them post Bahamut?

Maybe that weird flesh-like core underneath the Warring Triad Facility/ research center is how they combined flesh with ____? It might explain why Xande, Amon, and co all look like giant flesh-magitek hybrid.

Either way, it certainly gives a new definition of "The land's alive"
