Proof? In CT magic is manipulation of the four elements. Innates do not even need energy to use magic (as far as I've know, at least). By Innate I mean someone who can naturally use magic, by the way. Not the colours in CC.
Well, Magic is a force, and it conjures fire, lightning, etcetera and kinetically makes it move and stuff, and apparently Magic is measurable in CT. This doesn't even touch on the fact that Innates use in-game skill points to cast spells, which I would assume is like energy.
Plus there's the fact that the Zealians had to drain Lavos's energy to fuel their magic, and if magic isn't a form of energy, then we have a severe violation of the laws of thermodynamics, and Chronoverse's magic seems to work with SOME of the physical laws atleast.
The people of Zeal need energy to use magic because although they are gifted with the power to use magic, they do not possess the natural energy needed to manipulate the elements. So yeah, I see where you're coming from as all evidence shows that energy is needed to use magic, but that does not mean Magis is energy by any means.
Um...yes is does. If Energy is needed for something to function, then that function is also a form of energy. I mean, hell, even Matter is a form of energy according to modern science.
No, he is a well of energy and as such he can use that energy to use magic. Lavos is never spoken of (by citizens of Zeal, at least) as if he has magic, but he is said to have energy and power.
Energy = Power = Magic.
I think he means 'nothing that goes against the rules set down by the game itself'.
Maybe, but the point still stands. Nature is very ill-defined in Chronoverse, and the only things that can really be called "Natural" in any sense of the word without a shadow of a doubt is the Entity.
