In the beginning, LeBlanc, the God of Creation, created the world of Tetrania alongside five other gods. Seraph, the Goddess of Knowledge, bestowed civilization; Ragaere, the Goddess of Earth, brought fertility; Pigata, the God of Fire, and Agatha, the Goddess 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 prosperity for ages.

But peace was not eternal.

A holy relic, sealed for millennia within the Holy Empire of Lumenheim, was stolen by an unknown figure. This event triggered a series of inexplicable disasters across the continents. The Magic State of Astra discovered records in ancient ruins regarding a 'Seventh God'—an existence erased from history—and this forbidden truth began to shake the very foundations of the world.

The Holy Empire, seeking to protect the faith, and the Knight Kingdom of Valor, seeking to uncover the truth, eventually turned their blades against each other. On the continent of fertility, the roots of the World Tree, the source of all life, began to wither. The earth cracked, rivers lost their flow, and black fissures spread across the sky. Without anyone knowing why, the world slowly marched toward its end.

Then, in 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 first to seize its power was not a hero, but the legendary paladin 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,' and he intends to reveal the truths the six gods have hidden. His goal is not world domination. It is 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, preparing for the final war. However, Cardion was already evolving into a being beyond human limits by breaking the seal of the Void, and the heavens and earth were being consumed by his abyss.

At the moment despair threatened to cover the world...

A rift tore through the boundaries of dimensions, and a single streak of light cut through the black sky.

Not a person of Tetrania, but a single being 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.
