The Great — Sinnur Union.

The birth of this civilization has a certain story, originally in the K2-155 star system, there was a race called the Sinuor.

They have advanced into the Space Age on the home planet where they were born, and have observed the existence of other civilizations in other galaxies within the same star system as them.

The Sinuer people, who first stepped into space, showed a great thirst for profit, and the reason why they were able to develop space technology into space was because in the process of internal evolution of civilization, various consortia and forces were vertical and horizontal with each other, showing the extreme phenomenon that internal interests could not be satisfied with all individuals.

Therefore, when the Sinuer people discovered other civilizations in the same star system as them, the first attitude they showed was not friendship and communication, but thirst and plunder!

Coincidentally, at the same time that these Sinurs developed the space class, on another planet in the same star system, there was also a civilization that successfully entered space.

That civilization is also an extremely militant civilization with an ideology that has been in the home planet of birth for many years, staging melee and fighting, and finally in the chaotic times of tragedy, an outstanding king led his kingdom to sweep the entire planet with the most elite division, completing the unification of civilization.

The most efficient civilization is born out of chaos, and due to the years of turmoil, this civilization has continued to increase its technology in warfare, until the emergence of the king of the unified civilization, the civilization on this planet has developed extremely mature technology.

When the internal unification of the planet was completed, the science and technology of the entire civilization developed even more rapidly under the impetus of unified standards, and soon entered space, and quickly established a space fleet.

When two equally powerful space-class civilizations meet in the same star system, there is an extremely terrifying collision between different ideologies, different racism and different civilization concepts.

Thus, war broke out without surprise.

The Sinuer civilization and this imperial civilization have fought a war that can be called a great battle, and the fleets and armies of both sides are fiercely fighting in the star system.

Once the fleet of one civilization was fortunate enough to advance to the home planet of the enemy civilization, but it was soon successfully counterattacked by the other side with a clever plan, and the war lasted for decades, countless resources and lives evaporated in the war, and the two civilizations were comparable, but both maintained a certain degree of restraint.

Neither side wants to end this battle by completely destroying the other's planet and life, destroying the other's civilization.

This is a miraculous star system, and there are more than two planets in the star system where the Sinuer people and their sworn enemy civilization exist.

While the Sinuer fought to the death against their mortal enemies, their war also spread to the other three planets in the star system, three civilizations that were only a thin line away from space-class civilizations.

Due to the influence of the two giants, these three civilizations were also forced to join the war that they did not initiate and should have nothing to do with them.

As the war progressed, resources became more and more scarce, and the relationship between the two giants and the tripartite civilization became closer and more hostile.

The internal groups of the five civilizations gradually ran into the war with no future in sight, and when their top leaders were unwilling to give up their desire for victory in the war, a Sinuer who had come out of the bottom of the civilization stood up.

He united the bottom forces of the five civilizations, condensed them into a rope, and launched a vigorous movement!

End wars, coexist, and eliminate hatred!

A miraculous victory appeared, in the powerful low-level people's movement, the high-level forces of the five-party civilization, including the Sinuer civilization, were gradually defeated and overthrown, and the final victory of this epic war belonged to all the people of the five-party civilization.

It is precisely because of this victory that the five civilizations have the opportunity to merge into a whole, and after the death of the Sinur who led the five civilizations to end the war, his successors worked hard for a great goal, and finally achieved the feat of merging the five civilizations into one.

Since then, the internal groups of the five civilizations have eliminated their names for their respective civilizations, and have unified themselves to the outside world as the "Great-Sinnur Alliance".

They became a united and powerful space-class civilization, no, it should be said...... They had been together like that for quite some time.

Two hundred years ago, since the establishment of the Great-Sinnur Alliance, this civilization began to expand and explore abroad, until now, they have become an astronautics-class civilization with a practical control range of 100 light-years and dozens of star systems.

In the process of expansion, they also encountered more lives and more civilizations, but these civilizations were far less powerful than them, and far less advanced than them, but they also united those backward and ignorant lives into their own whole......

With the gradual expansion of its size, the external expansion of the great-Sinur civilization has shown unimaginable fatigue, countless internal contradictions have been exposed, the development and progress of the entire civilization have been seriously stagnant, and even the tragedy of mutual attack and hostility between ethnic groups within the civilization has once again appeared.

As a result, for nearly a hundred years, this astronaut-class civilization has been in a state of strengthening its rule internally, gradually shifting from external expansion to internal frenzied suppression, and greater problems have been exposed.

Until recently, the higher-ups of the Great-Sinnur Alliance received the critical news that their observation system reported that within a hundred light-years of their civilization's borders, there was a galaxy called "Catalokashi (Crimson Crow" in Sinuer), with a space-class civilization that was experiencing frequent activity and suspected expansion.

At first, they didn't pay much attention to the news, until the latest news was that an alien starship had broken into one of their border planets and destroyed a small patrol fleet of them!

So, they sent people to negotiate with them, and it turned out that this is a Kamigawa civilization, they know the existence of the Kamigawa language, a long time ago, before their civilization went into space, a group of mysterious species called themselves angels descended on their planet, led their ancestors for a while, and left them some texts, and there is still a belief in angels in their civilization today.

The Kamigawa language system is also known as the supreme sacred language in their civilization, and in the initial negotiations, these high-ranking members of the great-Sinnur alliance thought that they had encountered some sacred race, until the person they negotiated with vaguely revealed to them that the other party was from the "Galactic Federation", and they suddenly realized.

Then he showed hostility, since the other party is an aerospace civilization like them, destroying their patrol team for no reason, and occupying their planet, it will have to pay the price!

Although, it's just a planet that doesn't do much for them.
