Encyclopedia Magica

Mana? MP? Ki? No, here we have Ethe. Short for Ethereal Energy.

Also we have Runes. These of course being the lens focus some may need to properly cast their magic. Usually it's due to a form of ill ability, from either being a newbie, heavily injured or for lazy smartness otherwise called efficiency. It is honestly worth it to have runes though. Low on Ethe, no ability to recover it or your stamina? Runes. Like the 'more wolves' problem solving.

Thirdly & Worldly, the Magica Gears. Frankly, there are 7 holy, 7 unholy and 6 'neutral' Magic Gears that attach to a person's soul, in exchange giving them access to it's magic.The Magic Gears are sentient however, so some are more fussy than anything else with who they choose to be their new wielder. For example, holy gears will only want the most morally upholding party to use them. Though, this is partly because the gears are more compatible the most a person aligns with them. Though some have outright conditions on them.
 * Blessed: Alpha Wing/ Light-bringer/ Blade of Light/ Mirror Gear/ Series Gear/ Lucid Gear/ Infinity Gear
 * Cursed: Omega Wing/ Crimson G/ B-Luster Armour/ Absorption G/ Berserker G/ Chaos G/ Balance-Breaker Gear
 * Neutral: Aerial Gear/ Hollow Gear/ Dragonscale Gear/ Refraction Gear/ Crisis Gear/ Fenrir Gear

Trivia
Oh yeah, for anyone wondering, magic existing isn't a fix all situation.Yes, all countries have clean food and water, but, in exchange there are now families that actively exist to be magically powerful through selective breeding. Or as I call it, Rich-Rape. Seriously, being a magic-wielder has dozens of professions that will net a family vast sums. And since money is power, power makes things happen that you want to, you can imagine where I'm going with this, so I'll stop here.

Weird one, but magic that makes scientific sense like magnetic and flight, are actually rare. Why? Initial Ethe cost to use them enough to practise them, is stupidly high. Like move over Super Saiyan 3 and your 24 hours to 15 minutes, you've been slapped. Oh also plasma magic. But that kind of makes sense, because of the raw energy needed to turn gas into plasma. The others like lava and tsunami geysers, make sense from the focus and magic required.
