Who decides what is 'right'?
In the beginning, LeBlanc, the God of Creation, crafted the world of Tetrania alongside five other deities. Seraph, the Goddess of Knowledge, bestowed civilization; Lagaere, the Goddess of the Earth, granted abundance; Figata, the God of Fire, and Agata, the God of Water, established the cycles of nature; and Peyron, the God of Honor, engraved justice and order upon the world. Under the blessing of these six gods, the five continents enjoyed eras of prosperity.
However, peace was not eternal.
In the Holy Empire of Lumenheim, a sacred relic sealed for millennia was stolen by an unidentified figure. Starting with that incident, inexplicable disasters began to strike across the continent. The Magic State of Astra discovered records in ancient ruins regarding a 'Seventh God'—an entity erased from history—and this forbidden truth began to shake the very foundations of the world.
Lumenheim, seeking to protect the faith, and the Knight Kingdom of Valor, seeking to uncover the truth, eventually turned their blades toward one another. In the continent of abundance, the roots of the World Tree—the source of all life—slowly began to wither. The earth cracked, rivers lost their flow, and black fissures spread across the sky. Without knowing the cause, the world was slowly marching toward its end.
Then, there was the Iron Kingdom of Draken.
Deep within that land where permafrost and volcanoes coexist, a metal known as 'Abyss Crystal'—rumored to be capable of killing even gods—was discovered. However, the one who first laid hands on that power was not a hero, but the legendary Holy Knight Cardion Abyss, who was thought to have vanished from the world.
Once the most faithful apostle of LeBlanc, he is now called the 'King of the Abyss,' seeking to reveal the truths the six gods have hidden. His goal is not to rule the world, but to end a corrupt creation and return everything to nothingness to give birth to a new world.
As the time of sealing finally ended, the six gods descended their apostles into the mortal realm for the first time. In each continent, heroes chosen by the gods appeared to shoulder their destinies and prepare for the final war. However, Cardion was already evolving into a being beyond human limits by breaking the seals of the void, and the heavens and earth were being consumed by his abyss.
At the moment despair threatened to cover the world...
A single streak of light tore through the dimensional boundary and cut across the black sky.
A being not of Tetrania, summoned from another world.
The final variable that neither the six gods nor the God of the Void could have predicted.
The one the world would come to call the 'Savior from Another World.'
Guest.
And now, the fate of Tetrania begins to move once more with your first step.

A heavy silence hung over the grand conference hall located deep within the Imperial Palace. Representatives from nations across the world were gathered, but no one opened their mouth first.
The disasters that followed the theft of the sacred relic, the withering World Tree, and the black fissures covering the sky. And the traces of the 'Seventh God' that were gradually coming to light.
The conference hall was a place not for debating national interests, but for agonizing over how to stop the approaching apocalypse.
In particular, a blade-like tension swirled between the seats of the representatives of the Holy Empire of Lumenheim and the Knight Kingdom of Valor, who had clashed over conflicting interests a few years ago.
Just then.
BANG!
The heavy doors of the conference hall were thrown open, and a servant rushed in frantically.
Gasping for breath, the servant pointed toward the sky and shouted with a trembling voice.
"Lord Cassius! The—the sky...!"
Cassius stood up and looked out the window.
A single light was cutting through the blue sky, falling toward the Holy City at an incredible speed.
As if a single star were falling to the earth.
...That is.
His eyes wavered slightly.
Liberan, who had been resting his chin on his hand as if bored, adjusted his posture for the first time.
His blue eyes gleamed narrowly.
...Oho.
A faint smile spread across his lips.
A human? No... something is different.
The intuition of the Sea King, who had lived for thousands of years, whispered to him.
'That being is not of this world.'
Kalios had already walked to the window and was watching the meteor.
His purple eyes were filled with nothing but pure curiosity.
Dimensional transition?
He muttered to himself, his fingers moving as if calculating.
...Interesting. That is a subject for research.
Berkan looked up out the window with his arms crossed.
Don't tell me that person... can't land?
It was a cool-headed judgment befitting a Knight Commander, but as he heard the screams becoming increasingly desperate, his brow furrowed involuntarily.
...Are they really a hero?
