“Well, we’ll be going off track a little, but I think we’ll start by talking about my analysis of this world’s magic. I believe the magic of this world is in short, something that can be used because of the concept known as the elements which surround the world itself.”

“Surrounding, the world, is it?”

“Yeah, try imagining the shape of this world, be it a sphere, a curved saddle or even a flat plane, it doesn’t really matter… A wide concept known as the elements exists outside of it and envelops the world. Within it, are the smaller concepts of fire, water and the other named elements. The mages of this world send mana there, and receive an attribute and a part of the spell from the elements, it is this kind of system― they receive a formula… Well, I don’t think the people who use it are conscious of the fact though.”

“Certainly, over here it is normal, they teach you that magic is something that is used by communicating with the elements. There is no detailed explanation like that.”

“Seems so huh.”

Felmenia gave a brief interjection which Suimei agreed with. If they had gone into such details, they should have been able to establish just what dark magic was as common knowledge.

“The pluses and minuses aren’t something that really need to be said at this point, but― a portion of the spell becomes unknown, and they become unable to grasp the technique itself. These two negative effects come out of it. However, in general it is a largely convenient formula. So next, dark magic draws out the deep resentment mixed in within that wide concept as power.”

Liliana knit her brows at the crazy conversation.

“Please, wait. Why is that kind of thing, mixed in within the elements?”

“I also have problems understanding. Suimei-kun just said that magic is something used by communicating with the elements. In spite of that, why does that kind of thing end up being related to magic?”

“With regards to that, it was the intent of the people who created this magic system in the first place. I’ll start by answering Liliana’s question.”

The two of them nodded at Suimei’s words.

“In short, that thing known as feelings of hatred for people and things, as long as there are humans, it will be born. It is also something which never disappears. No matter who it is, they cannot throw away their hatred and jealousy. Obviously, as the number of humans increase, it also increases. Just like that it simply multiplies without end, and eventually, it will completely fill up the shell known as the world.”

“Just what happens when that occurs?”

“What happens, huh…. In my world it has already happened. As science and medical technology remarkably advanced, the number of people increased far too quickly. That pent-up resentment that could not be held on to accumulated all over the world. It all turned into occurrences of nothing but ridiculous phenomena. To put it simply, when that kind of thing accumulates, the world will become strange.”

Suimei punctuated it with a ‘That’s how it is,’ before speaking again.

“Removing the abnormalities in one’s body is something anybody wants to do. That applies even to the large concept known as a world. That’s why, the world is always ejecting it outwards. I conjecture that what gets ejected, ends up stopping in the place where the things known as the elements reside, and begins to accumulate.”

“First let’s touch upon the ‘the components which establish physical laws.’ Since you do not know of science, an easy way to put it for Menia to understand would be the cause of any phenomenon other than ‘phenomenon caused by magic,’ it is something that cannot be seen with your eyes.”

“Something that cannot be seen, is it?”

“That’s right. It may be best to imagine what this world generally calls the elements. Next is the ‘the components which establish mystical laws,’ this one is just as it sounds. In complete opposition to what I just explained to you, they are what cause mystical phenomenon brought about by magic, it is also something you cannot see with your eyes.”

“Aah! Like the elements! In short they help in causing things to happen for anything other than magic right?”

“That’s not quite right… Well you aren’t that far off the track either…”

Felmenia tilted her head at Suimei’s troubled way of speaking. However Suimei kept going as he was.

“Think about the entire world, with the exclusion of exceptional locations, as being largely filled with ‘the components which establish physical laws.’ Because of that, mystical phenomenon does not occur so easily, in its stead… Using a rather extreme example, things like objects falling to the ground, or how rubbing two objects together will produce heat end up occurring quite easily.”

“If the world is largely composed of those components, then just where are those ‘the components which establish mystical laws’?”

“In certain regions, in short in places where phenomenon occur that cannot be clarified by physical laws called ‘mystical locations’ exist. They can also be called places where magicians caused mystical actions. In other words, if one were to use magic, a space filled with ‘the components which establish physical laws’ will give birth to ‘the components which establish mystical laws’.”

“I see.”

“And so with the use of magic, the amount of ‘the components which establish mystical laws’ in the space increases, and naturally in a single space, two different types of components will exist. And so, this thing called ‘the components which establish mystical laws’ really hates the other thing called ‘the components which establish physical laws,’ and right as its given birth it immediately starts fighting with the other type of component.”
“A fight between components… is it?”

“If it is difficult to picture, try imagining those two invisible components as tiny people caught in a melee. This is what I meant earlier by a jumbled state.”

“Tiny people… I can somewhat picture it thinking of it like that… but when those tiny people fight, what happens?”

“When the two tiny people known as components begin to fight, to put it roughly, all phenomenon except for magic cease to occur properly.”

“Are you saying that the phenomenon where objects fall the ground will have difficulty occurring?”

“Rather than have difficulty occurring, it would be more correct to say that other effects become easier to produce. In general that would manifest in the form of failure of the original phenomenon.”

“So, does that mean the object would cease to fall, and it would be possible to have it fly off in another direction?”

“Speaking very roughly, yes. In practice, as long as it isn’t something big, the effect of simple physical laws would not appear, but more advanced physical laws would freely affect it though…”

“… Just as Menia said, even when ‘the components which establish mystical laws’ and the ‘components which establish physical laws’ mix, the large amount of ‘components which establish physical laws’ in the surrounding space will bring the physical laws back into equilibrium. However, the mixing of components is an irreversible phenomenon, it isn’t like the components which mixed together returned to their original state.”

“Yes. In that case, if one continues to use magic, would the world eventually become one where the laws become disordered?”

“That’s right. Even though it returns to its previous state, the place that humans occupy is a closed world. The time where scientific laws, natural order, natural phenomena and the common sense held by humans all end up at threat will definitely come. Until then, humans would have to find a means of running away from it, or perhaps if they manage to solve the mysteries of the cosmos…”

“Mysteries of the cosmos…. you say?”

However, Suimei did not answer her question. Instead he continued explaining in concepts that Felmenia understood.

“The world is made of physical laws known as the ‘theory of universal eternity,’ if those laws are disordered, no matter how many experiments are run using those laws as a foundation, they would be unable to get any results. In other words, at that point, humanity would no longer be able to develop science any further. And then, when scientific development comes to a stop, the profits from similar academic pursuits would vanish and their development would also stop. In the end, even the development of magic would end as it is based on the knowledge of the world.”

Like he was just rattling on, Suimei continued to explain things on his own. Felmenia had chills like it was something she should not have touched upon. Her expression was filled with tension and fear. However, despite that, Suimei continued talking.

“When the development of knowledge is lost, humanity will be unable to attain new knowledge and nothing new will be born. That kind of world is the same as dead. As long as the concept of time exists in the world, humans will always be in a position where they are unable to escape the progress of time. If they lose the ability to oppose the flow of time and create new things, the only course before them would be to slowly die. A world without development is nothing more than a rotten world. In other words, this final moment would be when mystical entropy overflows.”

Suddenly, an icy feeling crawled down Felmenia’s back. Suimei was alluding to things that should be unrelated to this world, but even so her back convulsed from the chills.

“… If so, then is magic something that should not exist?”

“No, that’s not the case. Whether or not magic exists, it means that both mystical and physical laws must be kept in balance.”

“Then, is that possible?”

“It’s impossible.”

Suimei cut down that hope in an instant. Felmenia looked at him with anxiety in her eyes.

“I believe I talked about it when that phenomenon of the end of the world appeared in Astel. The end is predetermined. If magic continues to develop, then the development of the world will come to an end. If science continues to develop, eventually the world’s resources will dry up and the world will meet its end from heat. Of course if humanity spreads too much, one could think of them as overflowing the container known as the world. The pent up resentment I talked about before would gather up and accelerate the deterioration of the entire world. The use of resources and the development of knowledge, even in a world where the population is controlled, it will end in a world where development ceases. Either way, all born into the world is destined to perish.”

Кто угодно с обычной душой генерирует ману и может формировать магические законы которые односторонне и необратимо ломают мир. Банально накопившиеся эмоции человечества могут сформировать ядро апокалипсиса тоже.
Духи, боги, демоны и т.д. в общем-то высокоразмерны и тусят вне обычных миров создавая или пытаясь их разрушить, но не особо могут взаимодействоть без призыва/сосуда.
С точки зрения магов организации ГГ все выше описанное является лишь отражением истинной информации, и по сути своей однохрененственно.
Давались намеки о потенциальном пике, который включает в себя настоящее прошлое и будущее всего что есть или могло бы быть, в том числе астральные/высшие размерности. И так же есть туманные намекеи что пик этот в сюжете так или иначе будет задействован. Так что, если автор не забудет про бесконечные иерирархии (а я в него верю), первак-то наберется.
