Eh. Somehow, I'm more inclined to believe the Lifestream theory.

Lifestream theory = Dust gains its energy from Remnant itself and is possibly crystalized Remnant life-force or something like that, just like Materia in Final Fantasy 7.

Though, there's also my theory that Dust is crystalized magic residue that's left behind whenever a Maiden dies. But I'm not entirely sure how that would lead to Dust being unable to work outside a certain range from Remnant, unless the whole reason Dust's energy is active and useable is because of its proximity to the planet on which the current Maidens live.

It would be an interesting test to send a Maiden into space - with precautions and a way to bail out if needed, of course. Though, I wonder if the Dust would just be reduced to 1/4 of its power, due to only being in proximity to one Maiden. Then, there's also the question of if certain types are tied to certain specific Maidens.
