Prologue: The Celestial War

In the beginning, before time was measured and before the stars were born, there existed a realm of unimaginable beauty and power—the Celestial Realm. It was a world where gods and mortals coexisted, where the skies shimmered with hues of gold and silver, and the air was thick with magic. The Celestial beings, ethereal and radiant, governed the balance of life, weaving the threads of fate that connected all living things.

Harmony ruled for eons. Composed of the most powerful beings, the Celestial Council guaranteed that the forces of light and dark stayed in balance. Among them was the wise and kind goddess Liora, who represented the core of creation, and her brother Kael, the god of shadows, who protected the night secrets. They together preserved the fragile balance supporting their planet.

Still, like everything else, peace is a transient illusion. Deep within the shadows, a darkness started to awaken: a sinister force trying to tear apart the very fabric of reality. This darkness was Selene, a formerly respected heavenly who had fallen to envy and ambition. Driven by her lust for power, she betrayed her family in order to seize the Heart of the Celestial Realm, an ancient artifact with the core of all magic.

Pulsating with the lifeblood of the world, the Heart was a living being. Some claimed it could let one bend reality to their will, therefore wielding unfathomable power. Selene thought she could remake the world with the Heart in her hand, throwing aside the Celestial Council and reigning as a dictator.

As Selene's power increased, rumors of her betrayal ran rampant. The Celestial Council gathered, their expressions worried. "We must act quickly," Liora demanded, her voice firm. "If we don't, she will destroy our world with chaos."

Kael, his face clouded by the seriousness of their fate, nodded in assent. "We have to defend the Heart at all costs. It is the source of our magic and the key to our survival."

But Selene was cunning. She gathered a legion of dark creatures, twisted beings born from shadows and despair, and launched a surprise attack on the Council. The skies darkened as her forces descended upon the Celestial Realm, igniting a war that would echo through the ages.

The battle raged for days, the clash of light and dark shaking the very foundations of the realm. Celestial beings fell, their radiant forms extinguished by the relentless tide of darkness. Liora fought valiantly, her light illuminating the battlefield, but even she could not stem the tide of Selene's wrath.

In a desperate bid to protect the Heart, Liora and Kael devised a plan. They would hide the artifact in a place where only the pure of heart could find it, ensuring that it would not fall into Selene's hands. As the final confrontation loomed, they gathered their remaining strength and prepared for the ultimate sacrifice.

"Should we fall, our legacy must endure," Liora declared, her eyes shining with determination. "We will not let Selene claim the Heart. We will protect our realm, even if it costs us our lives."

With a final surge of power, Liora and Kael unleashed a blinding light that enveloped the battlefield, creating a barrier that would seal the Heart away from Selene's grasp. The explosion of energy sent shockwaves through the realm, scattering the remnants of the Celestial Council and leaving Selene to rage against the void.

As the dust settled, the Celestial Realm lay in ruins, its once-vibrant landscapes marred by the scars of war. Selene, furious and vengeful, vowed to reclaim the Heart and exact her revenge on those who had betrayed her. The balance of light and dark had been shattered, and the echoes of the Celestial War would resonate through time, waiting for the day when a new hero would rise to restore harmony.

And so, the tale of the Celestial Realm began—a story of courage, sacrifice, and the enduring struggle between light and darkness. Little did they know, the fate of their world would soon rest in the hands of an ordinary girl, one who would awaken to her destiny and embark on a journey that would change everything.
