Fifty years ago, a calamity struck humanity in the form of a meteor. A blood-red meteor followed by many other meteors. The meteor brought a disaster that humans had never thought of. The meteor carried a blood-red crystal. People who saw the crystal would be reminded of the color of their own blood.

The crystal had a mysterious power to change the laws of nature on this planet. The power of the crystal not only changed the anatomy of animals but also the vegetation system in some areas in just a few years on this planet.

Animals infected with the crystal became larger than they should have been and more aggressive towards humans. Even some plants have tried to eat humans or maybe they have taken them as food for themselves. This situation has forced humans to fight the infected creatures. For quite a long time, humanity had a hard time fighting the monsters that emerged as a result of this calamity. Until finally humans have managed to create some resistance against those who were infected.

Within ten years after the fall of the crystal, humans finally created and developed some humans who had the power among them to fight the power of the crystal. Although the power of the crystal became stronger, and humans will also develop. But how long they can withstand the power of the crystal?

Here in Lunaris, the blood crystal is called Scarlettite among humans. This blood crystal has been an enemy of humanity for half a century. And its terrifying power has made many living creatures become ferocious. Humans call creatures that have been infected by the influence of Scarlettite as Corrupted.

The Corrupted attack has caused humanity to experience a significant population decline in all countries. So that only seven countries have survived for 50 years now.

These seven countries are only able to defend the area around their capital from the Corrupted attack. They built large fortresses around their capital areas gradually to defend against the Corrupted attacks that attacked humanity.

The fortress that humanity created has succeeded in defending against the Corrupted attack. However, the war against the Corrupted had already passed its peak. The crisis felt by several countries was already very visible, as well as the true nature of humans.

The year 765 of the Lunar calendar. The economic and resource crisis caused a war to break out between two countries, this war had caused many casualties between them. But the lose side would always be the most destroyed of the two.

That was what happened to the Republic of Trigolika. This small country in the west had been at war for the past ten years with the Hexalida empire. The war between them had reached its end. That was because the capital of Trigolika, Tourmalina had fallen into the hands of the empire.

In a few days, there would be an official declaration from the Hexalida empire, to announce that the empire had taken control of one of the great fortresses on the planet in Tourmalina. But what happened to the casualties among them? Would they announce it? Of course they would. But it was too late, corpses were corpses, victims were victims.
