I'm pretty sure Gynda and "Crimson" are straightup Dust users. They seem to fall in the "Mage" category and since Dust is the universe's Magic...Also, in the first episode we get closeups of jewlery that is most likely Dust in their bodies. Pyrrah seems to use some too in her helmet.

About AuraXDustXMagic, I believe things to be like this: Aura is the energy within the body. It dissipates the further it gets from it's source(the body) so it can only be used for close-ranged aplications(Shields, Healing, Shock Blasts). Dust is a form of "aura-shaping" device. It takes one's Aura and converts it in different effects(like a prism separating light). The Dust would react to the aura "injected" in it producing fireballs and such. Aura=Magic sounds a bit off because it seems to be more like raw life energy than something so elaborated as Magic. Think of it as Mana and it's uses as just manipulating that energy within and outside the body.
