Miasma had an adverse effect on Mana.
It corroded the purity of Mana, corrupting it and disrupting any Spell that was made using it as a source of power. Following this logic, it was very reasonable now that I really thought about it.
"In a world that knows only Mana, Miasma is a valid source of dread."
Dark Energy and Dark Magic… they pretty much stemmed from Miasma, and not Nether as I had initially thought.
'It's embarrassing to be wrong. Though, it's a relief that's the case.' Fortunately, I was able to look into the future thanks to [The Hermit], so I pretty much knew the events that unfolded before they did.
Still… to think all of this conflict was because of some Miasma. It was very valuable here—addressed as ultimate power—but in my world, it was just another source of energy.
'I guess power is relative. This world has a low standard for power, so the stakes are a bit low…'
