A simple, easy theory

[Pharoh Amon Khan III]

I still think it's an innate ability. Squall touches his forehead as if focusing mentally when casting Para-Magic or Summoning. This is why never thought there were no technology or devices involved, just telepath and telekenisis manipulating energy.

Also, because it is a natural with monsters I don't see how this excludes humans...

And not all GFs are 'monsters'. Odin is... something. Gilgamesh is an interdimensional anamoly, Eden is a Time Machine, Quesecotal seems to be quasi-sentient energy, but almost all seem to be more than just monsters. Too me they seem like inter-dimensional beings like Odin, maybe 'Old Gods'. But something less connected with monsters. Halflings.

So like I was sayin'...

I think that some Para-Magic effects are telepathic...

Meteor for example is powerful illusion and can the only defense against is the psi-screen effect known as "Shell". The physical telekenetic shield known as "Protect" has no effective defense at all against meteor.

These are just a two examples....
