Tree Diagram woke up from his silent sleep, and he immediately began to think and compute, it was the only thing he was good at.

He immediately was contacted by Accelerator, who passed from being angry with him to being worried that he had stopped working, so he was really relieved to know that he still worked.

He wondered since when he had started calling him using "he" instead of "it", just like if Tree Diagram was an human being. He called his name in his mind, and the computer answered "I am here, Accelerator"

Accelerator asked him why was he sleeping like that "I had to reflect on our next step toward the Golden Path, and I recently received an AIM signal from this city, it's a little vibration that I comprehended in his fullness. A new form of magic is coming, in this city" Accelerator then asked "And who is the wizard that is creating it?" And Tree Diagram laughed "you won't believe me, it's an Esper" Accelerator was shocked "WHAT?" and Tree Diagram explained "plus, it's an almost dead one.

You see there are many forms of Magic, but the main concept is unified: the Model theory.

Basically an object, filled with great power, is a source of magic power.

Now when a Wizard creates a copy of it, the copy is connected to the source and has the same kind of power, even if it's smaller.

And copies of the copy have the same power but smaller and smaller and so on.

Many magic objects and talismans work this way, they imitate a First Object, which is the most powerful and it's hold by the great Magic organizations.

Let's say there is a great Statue of a dragon, which gives the ability to create fire to those who use it.

It has the power to create 100000 flames per second.

If 100 copies were made, they would be strong enough to create 10000 flames per second.

If 10 copies of each copy were made, they would create 1000 flames per second.

And so on, always less power, but greater number.

But now a new form of Magic was founded, and an Esper did it."

Last Order suddenly was heard in the discussion "Well, Espers were models for Magicians, so you could say that Espers are the source of magic, and Magicians are copies"

Tree Diagram felt truly pleased for that consideration "It is exactly right, Number 20.001.

Espers were in fact the first humans to achieve supernatural powers.

They were persecuted, hunted, often killed, because normal humans were scared, or just jealous of their powers. Some Espers however had scholars, who learned from them how to have powers even though they were not "special", they trained them, they helped them to focus the inner mind's powers, and so, with a really hard training, a little part of that power was "copied".

That's how the first Magicians came to be, they were in fact all scholars of the last Espers."

Last Order felt the curiosity to ask more "Last Espers?"

Tree Diagram's voice became serious "Espers are today something known to mankind and studied in this specific city, but once they were something rare and unknown.

Once they were so little, actually their number is growing because we know how to find them even when their powers are so weak to be considered invisible, you probably don't know that, but not all Level 0 are just "simple humans", a great part of them are "Level 0 plus" or "Latent power" they have sleeping powers inside them, and they just need to be trained to discover them.

Then there are the "Level 0 potentials", they don't have powers but their brain is capable to achieve, maybe someday, Esper power.

As I was telling you, Espers were once very little, today their number is growing, but once it was decaying, they were in fact an extinct kind.

There were lots of them one day, living in secret from this civilized world.

They lived in other places that were partially undiscovered.

I'm not talking about Planets, which are easy to be inhabited, I'm talking about "closed spaces".

Let's say it's something like a space where only certain people can enter, the other ones will just see an empty place with nothing inside, while inside there is, for example, a whole city.

That's how Magicians are hiddening, by using closed spaces.

So once the Esper race was really prolific, but there was something I don't understand, Some Magic schools talk about a War, some talk about a great Monster, terrible and feared, some talk about a great catastrophe, some talk about a weakness, hidden in their kind.

However, their number decreased, and the last of them had the time to teach to normal humans how to use powers, and Magic was born.

Many Magic societies or Schools or Organizations in fact claim to be founded by supernatural heroes that they depict as really powerful, Espers.

Espers almost disappeared from this world, and Magicians developed, but Esper's kind never fully got extinct, because it's the next step of evolution, and that's why they are now getting numerous.

That's why Academic City is feared by Magic Organizations, they feel like their "masters" are goind to take Earth's control.

That's how Magic came to be, because of Espers, not because of Magicians.

That's why the new kind of Magic was founded by an Esper, and not by some Magic scientist.

This new kind is the "Ideologic Theory"

It's the exact contrary of the Model Theory

One person, let's say an Esper or a Magician, uses a symbol to achieve powers, and starts to believe that it has some power itself.

Because of the Quantic based power of Esper power, what an Esper believes in his Personal Reality influences reality itself, so the symbol begins to acquire a little power.

More Espers start to believe in the symbol, and it gains more "thoughts" by them, and so more power.

It becomes so powerful that even normal humans can use it and they gain power from it!

It this symbol's fame spreads in a huge amount of space, in that great space where many people believe in it, it will work, outside it'll be useless.

More and more people believing in it, more and more power comes from it.

If you realizes bigger versions of it, they gain even more power.

From 10 flames, to 100 flames, to 1000 flames.

You can then build a Nexus, a central object, which will contain all of that great power, and become an incredible source of power, thus making the Model Theory aviable for it."

Meanwhile in her school, Karin was holding her symbol close to her chest.
