[Introduction to the world view of the series of movies "Interstellar - Vast Sea":

In a certain cosmic space, there are many planets with intelligent life, and the technology of almost all planets has developed to the interstellar level at the same time, and after contact with each other, a cosmic scale struggle immediately broke out.

After nine centuries of endless conquest, five major political regimes have finally emerged in the pan-universe region, forming a pattern of peace and stability in a macroscopic sense, and since then, pan-universe technology has once again entered a new period of rapid development.

The five regimes are:

The "Hanhai Empire" dominated by both humans and humanoids.

The "United Kingdom of Saint Åland" that is purely human-led.

The "Federation of Cotesa" dominated by non-humanoid intelligent beings.

"Arturisde", which is dominated by the universe species.

A "central garden" where various species coexist in harmony.

The star field under the jurisdiction of the Hanhai Empire used to be the area where the struggle between humans and humanoids was the most intense, and in this place, not only humans and humanoids were fighting, but also within humanoids and humans, and there was a dark period that lasted for a century.

However, humans and humanoids have something in common after all, when their horizons widened as the interconnected areas of the pan-universe widened, and they came into contact with non-humanoid intelligent beings and cosmic creatures farther away, they became surprisingly tolerant to each other, and they completed the union in just thirteen years, forming the prototype of the current Hanhai Empire.

Although the Hanhai Empire is called an empire, it does not actually implement the imperial system, the so-called "emperor" refers to the vast scope of the entire regime, the most of the five regimes, although there is a royal family in the country, but it is only a mascot-like existence, and the real power is controlled by the eight major military departments in the country.

The royal family members of the Hanhai Empire do not have any privileges except for the name of "royal family", they cannot do business, cannot engage in politics, cannot marry any powerful people, and cannot hold any substantive positions in any institution, they are raised by the empire from birth to death, and their only role is to participate in various heavy ceremonies, wearing gorgeous clothes as a humanoid background board, only the emperor still has the job of holding a pre-prepared speech script, and the others can only poke there and do not move, to put it bluntly, they are the dolls of the whole country.

Because of this unique way of existing, the royal family of the Hanhai Empire has been born for eight centuries, during which countless members of the royal family have committed suicide due to various mental illnesses such as depression, schizophrenia, and severe delusion, which can be called a pan-cosmic wonder.

Of course, not all human beings choose to coexist peacefully with humanoids, especially those who believe in religion, in their opinion, humans are the most advanced and noble species in the pan-universe, humanoids can only be regarded as human subspecies, and other creatures are not even subspecies, in this context, the United Kingdom of St. Åland was born almost at the same time as the Hanhai Empire.

At the beginning of the pan-universe, there were thousands of human religions, and later, after the screening of time, there were four major religions and twelve minor religions, and then these sixteen religions influenced and merged with each other, and became three major religions in the middle of the pan-universe, and then subdivided various schools below.

At the end of the pan-universe, the Hanhai Empire was formed, and religious humans believed that they could not live in a country that allowed humans and humanoids to coexist equally, and immediately united to form a new force, and the three major religions also completed the final unification at this time, and the first co-pope was born.

As the name suggests, the United Kingdom of St. Åland is a religious power, its supreme authority is in the hands of the pope, and the core power of the entire country is controlled by the clergy.

The number of kingdoms and the division of regions within the United Kingdom of St. Åland are not fixed, because there will always be countries whose royal families will be purified because they cannot fully implement the will of the Holy See, and the vacated countries will be redistributed by the Holy See, or merged into the adjacent kingdom, or a new royal family.

And the Holy See of St. Oran is not monolithic, after all, it is the result of the integration of the three religions, there are many internal factions, there are frequent infighting between each other, and the kingdoms under their control are always used as guns, although on the surface they are righteous and awe-inspiring, but in private I don't know how many despicable things have been done.

There is only one broken star belt between the Hanhai Empire and the star fields under the jurisdiction of the United Kingdom of St. Åland, and on the other side of the Hanhai Empire, three standard star fields away is the Cartesa Federation, which is dominated by non-humanoid intelligent beings.

"Kotesa" means "non-human" in the lingua franca of the universe, which was originally a contemptuous term for non-humanoid creatures by humans and humanoids, but later gradually developed into the official name of non-humanoid intelligent creatures, so the non-humanoid intelligent creatures directly used this name as the name of the country after the establishment of the government.

There are more than 3,000 star fields of all sizes in the Federation of Cotesa, and if you calculate according to the standard star field, it is about 2345 standard star fields, so it is often called "2345" in the pan-universe.

Cotesa is composed of various star continents in the area under its jurisdiction, the same as the United Kingdom of St. Ålan, the number and size of star continents are not completely fixed, although they are managed by the federal government, but each star continent is also considered an independent small regime, and it is normal to have a little friction, plus there are many races, and some of the more chaotic areas will basically change the star continent division once every few years, and it is not stable at all.

However, most of the non-human intelligent races that have developed into the pan-universe period have a long lifespan, and longevity means peace of mind, although there are many internal strife, but in general, it is the most harmonious internal atmosphere among all regimes.

Farther away than the Federation of Cotesa is the Aturistes dominated by the cosmonics species, and there are a thousand standard star fields between the Federation of Cotesa, not to mention the distance from the United Kingdom of St. Oran and the Hanhai Empire, most of the people in these two countries have never been able to contact the inhabitants of Aturisde in their lifetime.

Arturista is also the most mysterious and feared of all regimes.

Speaking of political power, Arturiste is more like a synonym for a region, because everyone does not know whether there is a political system within those species.

"Arturisd" means "mysterious and powerful cosmic creatures" in the lingua franca of the universe, and is a general term for all creatures that can survive in the universe without the help of any external force.

"The upper and lower four directions are called 'Yu', and the ancient and modern is called 'Zhou'", the mysterious and powerful Arturisde was worshiped as a god by many intelligent creatures in the early days of the pan-universe, thinking that they were born directly in the space of the gods, until later someone hunted and killed a cosmic species, found that it was full of treasures, and immediately set off a wave of hunting frenzy, and the religion of worshiping Arturisd disappeared without a trace in an instant.

However, no one expected how powerful the Arturisds hidden in the depths of the universe were, and what would happen when they were provoked.

The sapient beings who lived through that period have died over time, leaving behind a thousand standard fields of no man's land between Arturiste and the Commonwealth of Cotesa.

It was a dead land, all the planets were in a period of decay, not suitable for any living creatures, all kinds of star changes were happening all the time, in addition to providing an excellent cosmic observation site for intelligent beings, they were constantly reminded of the invincibility of Arturisd.

However, no matter how powerful the power is, it is insignificant in the face of greed, even if there is a thousand star fields of no man's land, there are still many interstellar adventurers who choose to explore, and these adventurers eventually return less than one percent, but each one of them becomes rich after returning, so it attracts more adventurers to ......

Of course, not all sapient beings like to live in a prejudiced and hostile state, and nearly two centuries after the formation of the three-legged power of the Hanhai Empire, the United Kingdom of St. Åland, and the Federation of Cotesa, a regime almost the same distance from the three countries has gradually formed: the "central garden".

Originally founded by adventurers from several countries, the Central Garden grew to become an independent regime with more and more adherents due to the concept of openness and equality.

Because of the harmonious coexistence of various species, all international organizations at the pan-cosmic level have their headquarters in the central garden, which is also a highly developed country in various fields such as commerce, science and technology, and culture.

The power of the Central Garden was in the hands of the "United Association", and the whole country had a hierarchical system of joint associations.

There are associations in all legal areas of the Central Garden, and each association has a perfect hierarchical system, and the local government to the central government selects elites according to the proportion of the number of associations to form governments at all levels, so as to maximize the fairness and justice of the state power and take into account the interests of all parties.

Under such a political system, although it is still not completely possible to avoid infighting, the overall environment of the whole country is the best, and it is the most desirable immigration destination in the minds of the residents of many other three countries, but in order to protect the internal environment of the country, the access system is very strict, and it is not easy for people in the other three countries to become a citizen of the central garden.

Addendum: Pan-Universe Chronology (Timeline Mode)

-∞—The first year of the pan-universe: the period of independent development before the full exploration of the universe by all species.

The first year of the pan-universe: Humans and humanoids discover each other separately and have a preliminary understanding of each other.

In the first year of the pan-universe - 642 (the beginning of the pan-universe), the interior of the pan-universe was very chaotic.

From 643 to 726 (the middle of the pan-universe), the major powers began to take shape until they established their political power.

In the year 661 of the pan-universe, the Hanhai Empire was established.

In the year 677, the United Kingdom of St. Åland was officially established.

In the year 726, the federal government of Cotesa was proclaimed.

From 627 years of the pan-universe to the present, in the new era of the pan-universe, the major forces have gradually stabilized and entered a period of rapid development.

From 702 to 843 in the pan-universe, there was a century-long confrontation between intelligent beings and Arturisd.

In June 843, the 1,000 standard star fields between Kortesa and Arturistes became uninhabited in just one month.

In the year 913, Central Garden was declared an independent regime.
