The home galaxy of the Acadian civilization is a very unique twin galaxy, that is, in this star system, there are two stars with similar mass!

There are not many star systems with two or even several stars, and near the center of the Milky Way, some galaxies even have more than a dozen stars, but most of these star systems have a main star, and the mass of the secondary star is much lower than that of the main star, essentially becoming the planet of the main star.

In the Acadia system, the masses of the two stars are very close to each other, with the smaller one about eighty percent of the larger one.

Because both stars have strong gravitational fields and revolve around each other, a stable twin galaxy is formed.

The Acadians have given these two stars two elegant names, "Abgadi" and "Zayx". In the Arcadian language, they mean "priest" and "godmother", respectively. In the minds of the Arcadians, these two stars are the supreme gods.

In this star system, there are thirty-eight planets, of which seventeen orbit Abgadi, fifteen orbit Zayx, and six orbit two stars. The most special thing is these six stars, five of which orbit in a large elliptical orbit, and two stars are the two focal points of their orbits. The remaining one, on a figure-8 track.

The home planet of the Arcadian civilization is the planet with the most special orbit.

Obviously, the Arcadians should not thank their priests and gods, but Valentine, the creator of this star system.

The distance between Abgadi and Zayx is neither close nor far, and their respective life belts overlap in the middle region, thus forming a "8" shaped life belt, and the orbit of Acadia's parent star happens to be within this life belt, which makes it produce a very unique ecological environment.

According to the time on Earth, the orbital period of the Acadia parent star is about twenty years.

Of those two decades, Arcadia was in Abugadi orbit for seven years, nearly six in Zaix's orbit, and more than seven years in the middle of the two stars. In terms of ecology, the seven years in the middle of the two stars are ideal, because in two three-and-a-half-year cycles, each time there are about three years, and every corner of the Acadia parent star can enjoy sunlight.

Such a unique environment has made the Acadians extremely unique.

The vast majority of intelligent civilizations have overcome the natural environment in the natural evolution stage, and have evolved a strong reproductive ability, and their offspring are no longer affected by the environment and the season. Humans, for example, are able to reproduce in any season of the year, not in a particular season.

Not so with the Acadians.

In the Acadians of the year, there are a total of eight seasons, and only when the two "seasons of light", that is, when the Acadian parent star enters the middle region of the two stars, and all places enjoy the sun, will reproduce, and the offspring will be concentrated on the day of the arrival of the season of light. Although the Acadians were viviparous, they had a very short gestation cycle, only half that of humans. The new Acadians will try to use the rest of the Season of Light to grow quickly. Over the next three seasons, especially during the "dark season", when the Acadian parent star orbits to the outer side of one star and the other star is completely invisible, the growth of young Acadians will slow down, or even stop altogether. When the next season of light arrives, young Acadians enter their teenage years, begin to grow rapidly again, and mature before the season of light ends. After three seasons again, by the time the first Season of Light of the following year arrived, the newborn Acadians were able to reproduce.

Because the two seasons of light are intertwined, the Acadians produce a group of offspring every ten years.

These are not the most unique places.

The biggest difference between the Acadians born in the two seasons of light in a year is not the form, but the gender!

When the Acadian parent star enters the mid-star region from the Abugadian orbit, the first bright season of the Acadia year, the breeding Acadians are all males. In contrast, the Acadians from the orbit of Zaix enter the mid-star region, when the second season of light arrives, and the breeding Acadians are all females. That's why Arcadians gave the two stars that they were named like that.

In addition to their peculiar way of reproduction, the Arcadians themselves are strange.

If you have to find a suitable image for the Arcadians within the cognitive range of human civilization, it must be the elves in the novel.

Of course, the Arcadians are very different from the imaginary elves of humans.

Even across the galaxy, the Arcadians are a very unique and intelligent being.

It is important to know that almost all intelligent organisms, including humans, have evolved from animals, because only animals can produce complex social relations, have the ability to adapt to changes in the environment, and evolve rapidly in a changing environment, and it is also possible to produce intelligence.

Of course, it is not that there are no intelligent creatures that have evolved from plants, but they do not require extremely special environments.

The Acadians are neither animals nor plants, but rather a creature between animals and plants, possessing the characteristics of both.

The ancestors of the Acadians were parasitic creatures. In order to adapt to the drastic changes in the environment, the organism that was originally attached to the plant has evolved locomotor organs, which can also find a new host elsewhere after the environment changes or the host dies. On the home planet of Arcadia, this unique survival technique is becoming increasingly important, and athletic individuals tend to have more opportunities to reproduce. Over the course of a long evolutionary process, the ancestors of the Acadians eventually evolved into animals. This is not entirely accurate, as the ancestors of the Acadians were not animals and retained many of the characteristics of plants. For example, the body contains pigment cells that can produce nutrients through photosynthesis and can survive extreme environments.

Of course, the Acadians fully inherited these virtues from their ancestors.

After evolving their intelligence, the Arcadians retained many of their original habits, such as living in forests and coexisting with many plants. Although the Acadians are no longer parasitic, most of the nutrients they need still come from plants.

It is precisely in this way that the Acadians can be connected to the imaginary elves of human civilization.

Of course, the complex environment is still responsible for all this.

In a sense, all of the characteristics of the Acadians are related to the environment, especially the twin galaxies, which are made up of two stars, and the unique orbit of the Acadian parent star. Strictly speaking, these two stars have the greatest impact on the Acadians.

In the natural evolutionary stage, the Arcadians possessed certain abilities that other intelligent civilizations had in the self-evolutionary stage.

For example, the main means of communication among the Acadians was not language, but telepathy, or the exchange of consciousness.

Although the Acadians also had a language for ease of communication, and it was a common language, for a long time during the natural evolutionary phase, the Acadians did not have a written language. Consciousness communication is more about the exchange of images and sound information, and language is only needed when it comes to individual thoughts, and it is often just some abstract thinking, if it is a description of events and things, it is mainly based on image and sound information. It is precisely because of this that the Acadians did not have a lot of meaning in writing at the beginning of civilization. It was only later in the natural evolutionary stage, when the amount of information that needed to be recorded increased, that it was impossible for any single Acadian to preserve so much information that writing appeared. At that time, the main role of writing was not to communicate, but to record history.

The fact that the Acadians gained the ability to communicate so early was due to the two stars.

That is, in the middle region of the two stars, the various radiations are greatly enhanced after superposition, which has a great impact on the life on the Acadia parent star. This effect allowed the ancestors of the Acadians to be separated from the earth, and also allowed the Arcadians to evolve intelligence, and also made the Acadians extremely developed consciousness organs, that is, thinking organs similar to the human brain.

Without such a complex environment, it would have been absolutely impossible for the Arcadians to possess so many characteristics.

It's just that in the stage of self-evolution, the science and technology of the Arcadians are not developed, and they rely more on the improvement of their own abilities to enhance their survivability.

Fortunately, Valentine was the second group of Dimension Reductioners and came to the Acadia system very early.

Under his guidance, the Arcadians quickly entered the stage of self-evolution, achieved qualitative energy, and also developed a powerful technological civilization.

In fact, before Valentine's arrival, the Arcadians did not step out of their home planet at all.

After entering the stage of natural evolution, Arcadians discovered the true face of "Father Priest" and "Mother God", and had a more comprehensive understanding of the Arcadia galaxy, and began to explore and develop other stars in the star system, moving towards other star systems.

Of course, it was still a microuniverse at the time.

If it weren't for Valentine, the Arcadians might still be the elves of the forest.

It is not unreasonable for Valentine to choose the Acadians, because when he came to the three-dimensional space, many intelligent civilizations were born in the star system created by him, and he did not choose other intelligent civilizations as carriers, but chose the Acadians who were not technologically developed.

This choice has a lot to do with the peculiarities of the Acadians.
