My fantasy world is actually just Earth millions of years in the future, and as such I'm trying to superficially justify existence of some magic (mostly elemental based).
Idea is, civilization as we know it has destroyed itself, millions of years later a new race of humanoids develop and instead of technology, they research their mind and mental possibilities, and with that learn how to control and alter limited amounts of energy. Now, as energy cannot just be created from nothing, those primitive future mages would need a source of energy which they would drain to create for example an electric discharge close to them.
If it's possible, I would like that source to be in a form of dusty substance that can be ingested or even inhaled (that gives way more energy than food), which (from the writers perspective) opens up a possibility of "mana junkies" and overdose. Is it possible for such a substance to exist?
And if this ideaWhat is the best substance to generate enough energy in a complete nonsense I am openedbody of a humanoid being which is roughly equal to suggestions :)the energy needed for creating a thunderbolt or a similar manifestation of "magic"?
