i had an idea since i saw the second episode, when Weiss talked about dust. dust is the main source of energy in this world and gave the humans the necessary advantage over the grimm.

so what if the supply of dust is much more limited than expected. every civilation, current or ancient, collapses if they have no energy supply.

what might be the effects on normal life? who could benefit from this? may there be an alternative energy source? these are some of the many questions coming to my mind.
