Before the era of long peace, chaos reigned. Angels, the agents of God, and Demons, rulers of Hell, waged an all-out war for a millennium. The fight was not in Hell, nor in Heaven, but in our realm—Giaria, the realm of mortals.

More than the forces fighting, the mortal realm suffered the most damage. Soil lost its life, water its purity. Mortals were driven to the corner. A war that would not settle—celestial fire rained down from the sky, shattering earth, while dark waters surged from the depths below.

On the brink of destruction, a hero rose among them—not born of blinding light nor devouring shadow, but forged from pure desperation. He tore through the sorrows of a dying world and became a new symbol of hope.

He tore through the battlefield. He had no sacred weapons like angels, nor powerful magic like demons. All he possessed was his spirit—driven by the hopes, anguish, and sorrow of his people. Sacrificing his own flesh and blood, he sealed both armies away—locking the demons behind the Gates of Hell and the angels beyond the Heavenly Passage. He did what a millennium of war could not—he fought until his last breath, and with that final act, he won. He brought peace to his world.

The era of peace began, and thousands of years passed.
The war of a millennium—later called the Aion War—faded into legend, remembered only as a fairy tale told to children.
The hero who saved Giaria was revered as a god throughout the realm.

Across the oceans, there existed a prosperous empire called Regis. Its advancement was unmatched, known for its eternal peace and strongest military—yet it was gone.

A new force arrived, not with the heavenly power of angels nor the dark pressure of demons; it was something entirely different. A single attack vaporised the country in an instant, including all its citizens and armies. In the place where the empire once stood, there were no ruins, no ash—nothing. It was simply gone.

Only a single witness remained. It was a lone scholar who had left the country and saw the events unfold. He was trembling in fear, his mind shattered, staring blankly at the empty horizon. A being he could not describe, a presence he could not decide whether to revere or to fear, stood beyond his understanding.

A single word escaped his lips—

"Valariun."
