We've been given a decent amount of information regarding the properties of Dust and Aura. We've acknowledged that Dust is the prime energy propellant used for weapons and machines, and that Aura resides in any person (aka non-Grimms) which varies in intensity depending on that person and his/her capabilities and skills with Aura. That being said, since Grimm have been around since the dawn of man, suppose you "rewind" the clock to before modern technology and complex machinery - to a time when man had just discovered Dust but without the technology to harness it as they have in the current setting - how would man be able to use Dust effectively?

A lingering theory I've had is that a person's Aura is able to manipulate and activate Dust. I first thought of this after watching Episodes 1 and 2 back-to-back, when I heard the beginning intro and later seeing Ruby 's sneeze triggering the Dust. This led me to question how Weiss's and Glynda's Rune Casts were made: by their Dust-infused weapons, by their Aura, or perhaps both? I don't have enough evidence to support any conclusion, but I strongly believe Aura can trigger Dust, and that Dust can amplify Aura to a degree.

Please share your thoughts on this.
