Soul-Born Magic

THIS IS ONLY CANNON IN SELECT PARTS OF THE LORE.

The Soul-Born Magic utilizes the Elan Vital within a soul in order to do magic.

Elan Vital Details
Elan Vital is a form of energy, just like heat. What Elan Vital is to your soul is like what ATP is to your body. It can be replenished through simple waiting, but it has a maximum value. This maximum value can be increased via training and pushing yourself to the limit, though be careful, push too much and you'll literally lose your soul.

Elan Vital is supplied by your body, so your body is a big player in this endeavour. Every body has a "Natural Elan Vital level". This will dictate your maximum value upon birth. While you can increase your maximum elan vital amount by training as I said, there is a problem. Your Maximum Elan Vital amount will try to go back down to the "Natural Elan Vital Level" of your body unless if properly maintained with training. There is no way to change your bodies Natural Elan Vital level, other than small deviations during child birth.

This is why some people consider taking the extremely risky option of soul binding. You would have to get your Maximum Elan Vital amount high enough to match a stronger host bodies Natural Elan Vital Level, and then perform a soul bind, where you will be able to maintain your Maximum Elan Vital Amount. If not done correctly, this will lead to the loss of your soul.

When training, you must be careful, because when you are rapidly depleting your Elan Vital levels, at some point, your consciousness will shut down. If you manage to not pass out and continue training, and somehow drain all of your Elan Vital, you will lost your soul.

Soul Born Magic: The Basics
First thing you need to know when doing soul born magic is to manifest your Elan Vital to outside of your body. This is as simple as breating in and out once you get used to it however.

The far bigger challenge is knowing what you are doing. The biggest drawback and limitation to the Soul Born magic is not your endurance, but your intellegence.

If you want to lets say, create a giant flower for whatever reason, you'd need two things, a flower seed, and an understanding of how a flower grows. Plant the seed, and then manifest your Elan Vital as an energy source for the flower. Guide it to be a gigantic fucking flower. This is only possible if you know what you are doing to the flower, how it would've grown naturally, and how your energy can help it.

This generally limits complicated usages of Soul Born magic to those with better education, and those not educated resorting to more elemental types of magic, such as fire. This is the reason Soul Born magic can be used to boost the technology and the industry in places like Ukiala in Navi'Albah.

Information Chambers
There is a way around the biggest drawback however: Information Chambers. Similar to how other magic systems such as Full Metal Alchemist have some sort of drawing in order to conduct magic, we have writings. They are called "Information Chambers" due to them generally being drawn in circles, though it is not a requirement. These chambers have all the required information for a magic to happen, and by letting your elan vital manifest using this information, you can achieve things that are normally impossible with your knowledge.

Again, Information Chambers usage is divided in the lines of poverty and wealth too. The more industrial magic users may use sophisticated machinery to produce small information chambers that have thousands of lines of description of a even more complex machine, that can be used in the industry, while more lower level classes may use information chambers to make their lives easier.

As for combat, Information Chambers are sometimes useful as a tool for support, however is not that widely used due to the hastle and slowness of having to carry around a paper, iron etc circle. This is why many magicians just prefer to memorize their spells. One exception to this are tattoos, which cannot be that complicated due to them being tattoos, but can be more easily utilized during combat for relatively more complex spells that may be hard to execute under the stress of a battle. So basically, Information Chambers in battles are more reliable, but more slow, even as tattoos.
