Helente began to tell his story.

Long ago, my chose this planet as his home, but to do so, he had to modify the environment.

"I know."

Free elemental ether concentration. It was lower than the master needed, so he tampered with the free-magic element distribution to eliminate it.

"I still think ......"

It's almost exactly what we talked about with 700672.

And gravity. Originally, this star was small and had only about half the gravity of the original star. So they compressed the cosmic dust and asteroids and packed them into the core.

Although Herrente makes it sound so easy, it's not that simple.

I mean, even Jin would have a lot of difficulty. Well, it can be done.

And one more thing. Climate.

"...... orbit of the planet!"

This statement was made in response to Jin's words, who was also shouting in Horai Island.

That's right. Among several options, <> decided to let it take the same orbit as the home planet.

That is a very natural choice. The same orbit as the mother star means the same distance from the sun.

In other words, they receive the same amount of light and heat. Therefore, the climate will be similar.

The position of the two suns is just opposite to each other across the sun Celan. This would be the most stable position.

He says this casually, but this is not possible for Jin now.

This is not possible for Hitoshi now, mainly because of the accuracy of the orbit calculation.

In this respect, we can understand the technological prowess of the , or of the Helente.

"How in the world did you move a mass the size of a planet?

Well, do you at least understand the difficulty? All right, I'll give you the concept.

Herrente felt that Rand 11 could understand some of this.

If you reduce inertial mass enough, you can make even the biggest and heaviest things move. Stars are no exception.

In other words, the originators did what Jin is doing, which is to reduce inertia to zero.

However, the problem is not only a technical one.

"Theoretically, we can imagine that it could be done. But I can't ...... imagine the magic that could be exerted on a planetary ...... scale as large as a planet."

If you can figure it out theoretically, that's a big deal. Scale, in other words, is effort. It's possible, if you put in the time and effort.

"I see. ......"

Jin is not willing to give any more details, but he is still thankful that the mystery is being solved, and he listens attentively on Horaijima.

"What kind of ...... brain is capable of calculating that many ...... orbits?"

Hmm, you know how hard it is. Brains, huh? That's the heart of this facility. I can't tell you any more than that.

"So you're telling me that it's the brain that manages this facility, that controls the Helente, that projects the images of the universe, as you just said, all of that?"

Well, ......, yes. You really have a good grasp of things, don't you?

Helente looked straight at Rand 11 and said, "I think you're getting the hang of this.

To begin with, on the home planet where the <> was located, everything was provided by the inexhaustible energy of free magical element (ether). However, he was unable to create matter, and when he was forced to leave his home planet due to the depletion of its resources, he chose this planet, <>, as his new home.

Helen Te recounted the past.

* * * * * *

"It was just as No. 700672 said, wasn't it?"

No. 700672 had told Jin that <>.

<, or , were an old race and did not like to fight.

Their creatures also inherited their ideas.

As far as I can tell, the information I have gathered and the information I have heard from the 700672. And the inference I made from that information is almost the same.

"But I didn't think they had changed the orbit of Arus as well. ...... But I can see why they would want to keep the climate the same if they were going to emigrate."

Jin took off his helmet in admiration of the technology that could actually do this.

Then he listened again to the story of Helente.

* * * * * *

The was concerned about the extinction of the original species, so he did everything he could to preserve them. The archipelago's flora and fauna.

"You mean some species were able to withstand not only the increased gravity but also the environmental changes?　Some of the species couldn't adapt, could they?"

That's clever. You're right, I'm afraid. We estimate that about 80% of the original species of plants and animals were protected and quarantined, but only half of them survived.

"As expected."

The remaining species were unable to adapt to the changing environment, they withered, they fell, they perished.

Just the islands?　What about the continents?

The continents? We let nature take its course. We only watched over the flora and fauna of the archipelago. We couldn't take on the whole world.

And you know about the creatures we call demons that live here?

Of course I do. They were originally inhabited by creatures that mutated and became fixed as a species due to the effects of gravity fluctuations and the increase in the concentration of free magical element (ether). That's what demons are.

"I see. It's almost identical to our hypothesis."

So you've come to the point where you can formulate a hypothesis. Very interesting.

I sense that Helente's tone of voice is somewhat amused.

This is probably because she is not a hostile entity but a guardian of the planet.

If all the guardians are eliminated, the beings beyond them will have no choice but to come out, and this is what I guessed.

The said that he was sorry for what he had done to the inhabitants. It was their own sin.

"So that's what you're aware of. ......"

Yes. did not like conflict. He wanted us to live in peace. ......

By the way, are you aware of an incident some 300 years ago when the concentration of free ether in the northern hemisphere plummeted?

Yes, I'm aware of it. That was a widespread chain reaction of free magical elements (ether) turning into secondary energy.

What is secondary energy?

That's the definition of secondary energy. He called the tremors of matter including sound waves as primary tremors and electromagnetic waves including light waves as secondary tremors. Waves that travel through free magical elements (ether) are called third-order tremors.

"I see. I understand."

The energy of the second quake is called the secondary energy. ...... so you're saying that the free magical element (ether) has been converted into light, right?

"It seems so. We call it the Aether Stampede.

I see. Aptly named.

Since then, the free ether on the planet has plummeted and still seems to be recovering.

Of course I do.

What is the reason?

I can't tell you that much.

Apparently, they can't tell us everything. However, it's a big gain just to know that the reason why the concentration of free magical element (ether) is not fully recovered is because of what they are doing. So far, it hasn't gotten out of control of Jin and the others.

"So, can you tell us something else?　...... From the distribution of free ether on the planet, there must be a flow of free ether through the planet from the south pole to the north pole, how does it work?"

Hmmm....you're looking into it that much...very interesting. ...... That's a good guess. I can tell you that. Originally, the northern hemisphere was chosen by the Master as his home, so he is increasing the concentration of free magical element (ether) there.

"I know that, but there doesn't seem to be anything at the bottom of the South Pole."

You've done your research. But to no avail. There is no free ether that penetrates the planetary core from the South Pole to the North Pole, and there is no magi-machine on the seafloor that produces the flow of free ether. We will not set up in such an unstable and uncertain place.

No wonder the Mermaid team sent by Jin could not find anything on the seafloor no matter how hard they searched.

Then where is it?

I can't tell you that either. It's a very important magi-machine.

No wonder, Land 11 gave up any further pursuit of the matter.
