Chi. Xi. Chakra. Mana. Magic. Aura. Aether. Ether. Spirit. Soul power. Heart strength. Divine blessing. Force of life. By whatever name you call it, a mystical force of energy has existed since the dawn of time. Humanity has the power to tap into this force, yet most uses of it are instinctual or habitual rather than intentional.
Though some religions once taught how to tap into this ability, even their uses of it were limited by their rudimentary knowledge of the universe, and while their knowledge grew to be vast, they lacked the finesse for the fine control and mastery of the art, which science progressively began to replace.
...However, this force is not some mystical power that defies explanation. Though science had been slow to understand it, through time and experimentation, they have begun to unlock its secrets. Eventually, by combing through the records of the many ancient cultures that taught about it and combining it with modern understanding of how the world works, a scientist by the name of (*insert some impressive name here*) made a breakthrough.
The secret proved rather simple to learn, in fact, and once he had unlocked its true nature, the world began to boom with what he dubbed the Elixir Wave, AKA 'The Lix'. The Lix revolutionized the world, managing to solve almost every problem humanity had been suffering from...yet with it, came a curse:
It turned out that humanity was intentionally being blocked from tapping into the Lix. For the supernatural beings of myth and folklore exist within The Lix: ghosts, demons, gods, all with near-limitless power and mastery of it, granted immortality by the magic of the Elixir Wave. While plenty of benevolent entities exist within The Lix, angels, gods, and all, these malevolent entities consist of the majority of spirits residing inside, and thus, pose a threat to humanity:
Possession, insanity, corruption, haunting, they do all this and much more. Before the discovery of the Lix, they managed to occasionally break the barrier and wreck havoc on a minor scale, but always contained and quickly forgotten about, written off as nonsense. Yet now that the entire world has been exposed to the Lix, the gate is wide open, and they are now humanity's main menace.
While humanity has begun to expand outward to the stars and to the other dimensions the Lix unlocks, they must still face their own demons they have unleashed.
And this story is about their struggles to do so.
...More or less, anyway. I'm thinking it'd basically follow a magical task force, probably taking inspiration from various sources, like my occult friend. (For instance, the power of the Elixir Wave allows for people to expose their true selves, allowing people who're transgender to far more easily transition.) At least one member would be a native of the Lix on the good side; it'd be possible for there to be others on the team, even ones that're normally not so good, yet for whatever reason, are working for the heroes anyway. (Bound to them as a familiar, owe them a debt, are a bit of a troll and not really evil, you get the idea.)
The usage of the Elixir Wave would basically be science turned magic, magic turned science, in that it's strictly defined what can or can't be done. You can be very, very creative with your basically-infinite resources, but there are still rules in play with how the Elixir Wave interacts with the physical world. It'd also allow for some neat magitek: things that ALMOST are viable in our world, yet which aren't quite there yet. The main function of the Elixir Wave is basically that it's tied--loosely--to the concept of Dark Energy and Dark Matter, and that science now being able to harvest it, has a near-unlimited energy source that basically regenerates and recycles itself with no entropy.
I'd have to do a lot of homework to make it work, though, so probably not something I'd actually be likely to do. Alas.
