War. That was the beginning of all the destruction on this planet. The selfishness of those who possessed power made life on this planet feel like living in hell.
Terra Vitae was the name of this planet, once brimming with life. Various races of living beings, such as Humans, Elves, Dwarves, Dragons, Beastfolk, and others, lived harmoniously across its land and seas. But that beauty began to crumble because of the greed of those who held power.
The war between races continued with wars between nations, then wars between continents, causing life to slowly vanish. Everything grew even worse when the Human race created a deadly weapon of mass destruction, wiping out countless lives. By the end of the war, the planet was polluted, and plants had become nearly impossible to find or grow anywhere on it. Those who remained began to rebel for the sake of their survival. Then, one day, a civil war erupted in the Human lands, giving rise to a new hero who united all the races and brought an end to this long war.
The hero proposed peace, but the world had already been devastated by tainted mana and severe pollution. This made all the races begin considering the search for a new planet to inhabit and leaving this one behind.
With the combined technology and science of every race on the planet, building ships capable of traveling through space was no longer impossible. In just two years, they succeeded in creating a spaceship capable of exploring the cosmos. A single ship carrying heroes from every race was sent out to search for a habitable planet. After five years of exploration and determining the coordinates of habitable planets, they returned and announced that they had found many habitable planets for all the races. Preparations for the mass migration began across Terra Vitae.
With the planet's natural environment already too damaged for environmental rehabilitation, all the peoples of every race agreed to migrate to other planets. Since so many planets had been discovered, several races decided not to live together, so their painful history on this planet would not repeat itself.
Each race had a planet of its own. Even so, they all agreed to form an alliance and never attack one another. Through interplanetary trade, the leaders of every race agreed to designate one planet as the interspecies trade and diplomatic hub. That planet became known as Ouditors, where all races could gather freely under the strict rules of the racial alliance.
Hundreds of years passed, and everyone forgot their home planet. Terra Vitae was never remembered, for it held a tragic history for all the races. It was thus given the name Acheron, the dark and poisonous planet of tragedy and isolation. Its location remains unknown to this day, as though the planet where it all began had never existed and had become nothing more than a fairy tale.
That was the story known to the public. But to the nobles and the descendants of the hero who knew the truth, that place held their dark history and the difficult decisions they had made for the sake of saving countless lives.
