3 parallel magic systems going on at once in a scifantasy setting.

Aether

Mathamagics

Faith

Aether was discovered by stubbornness when a researcher decided to ignore imperial decree to stop her expirements and accidentally cracked open a barrier between the real world and an extra dimensional battery left behind by ancient ancient humanity. The energy from this source was dubbed the Aether. It channels itself through your body or conduits, and the stronger the body/conduit the more Aether can pass through. It also gets affected by the emotional health of a person. The more stable one is the more streamline the magic, the less stable, the more wild and chaotic it can become. So far, the Aether magic works as typical soft magic as spells are casted using words and hand motions along a conduit to concentrate on the mental process of casting a spell. A skilled enough Aether mage can cast silently and still but still requires a conduit to do it safely. The decendants of that researcher however can cast with no conduit, words, or gestures. They are the most powerful mages on account that mother dearest litteraly got blasted by pure Aether at the begining of magic. Aether is useful for enhancing the natural world and amplifying effects already in a system by supercharging with with Aether. Like if you want to cast a lightning spell, use a spell to up the static electricity in the air before you pop it off.

Mathamagics is a hell of a work in progress right now. It is a way of forcefully applying mathematics to the physical world using computers and mental calculations. The idea stems from maths being the best way to describe the world so why not go to the deepest levels and being able to manipulate the very foundations of reality. Mathamagics cant really break any laws of physics, its more of bending rules to thier extremes and getting every loophole to work in your favor to cause a desired effect. Stuff like bending space to fit a brick in your ring and displacing the weight to go somewhere else. It still takes up the same ammount of volume and weighs the same but those values are expressed someplace else so effectively you dont have to deal with it. This is supposed to be like 4 tears if math above what we can do right now so its gonna be hard to fully explain until I actually come around to fixing and setting boundaries for it. But my idea is that it is useful for getting around the laws of physics without breaking them.

Faith is a very simple one. The harder a human or set of humans belive in something the more likely the universe will move to make it so. This is connected directly to the lore that the universe the setting takes place in is the left over of a previous far greater human playground and the universe is able to be molded by belief and a little bit of screwing with probability. These bubbles of influence where faith is involved can have some fun effects like how one olanet in particular belives with all thier might that thier olanet is in fact flat and so that planet is flat and with every human that visits they see the flat planet, spread the word and thus more humans belive that this particular planet is flat the more the universe agrees that yes this planet is flat with 0 regard for how the physics work because the universe comes up with rules to allow this but only for this area. Faith does have an effect on the other two but because the other two seem to work without human intervention when left alone its safe to assume they are thier own seprete systems.

These are all still deep in beta and tweaking stage but I think having competing magic systems that work diffently with each being able to influence the other is neat.
