This gives a whole new perspective on the line: "We are lightning, Straying from the thunder, Miracles of ancient wonder."

If dust is mined, and is formed by remnants of dead organic (human and animals, maybe trees, do trees have auras?) matter, it could be considered a fossil fuel. I would like to know how much time it would take and what conditions are required for the forming of dust ore. Also, how much dust does one entity form?

As mentioned in the intro of volume one episode one, humanity was pushed to the brink of excistence before finally finding the stuff. This reinforces your theory (as you already kind of stated in one of the comments), because humans would need to die to form dust. I guess that eliminates animals and plants as dust sources, because humans would have found it sooner.

Dangit, now I want to know if Remnant has the same fossil fuels we have on earth.

My apologies for the lack of structure in this comment, it is just some thoughts.
