THE GREAT WAR
⤷ percy jackson & the originals
crossover.

❝ I vowed, I would always be yours ❞
—Taylor Swift

Kiara Hope Mikaelson-daughter of the sun god and the original hybrid, born in the space where light and darkness entwine—would be remembered as the one who put an end to the reign of the gods.

From the very moment her soul flickered into being, Kiara knew she was an anomaly, a wound in the fabric of the world. She was not merely a demigod—she was something both celestial and cursed, woven from the warmth of her father's sun and the eternal coldness of her bloodline's night. Yet, in her rarest of fortunes, she was loved. She had the gift most demigods could only dream of: two parents who would defy the heavens themselves to keep her safe, even when fate's cruel hands tried to rip them apart.

But then, one winter-icy and unforgiving—everything began to unravel. A vision, a glimpse of Percy Jackson and Poseidon, became the first thread in the tapestry of her undoing. What began with an innocent excursion to the Metropolitan Museum of Art in New York soon twisted into the revelation of her truth—her best friend uncovering the secret she had long hidden. The world she had known shattered, and Kiara found herself bound in a war neither she nor the Moirai could hope to control.

From that moment, her life became a symphony of blood and fire, of choices made and lives lost. It was no longer about Percy, nor the gods. It was about everything she cherished—her home, her family, the fragile hope of freedom... and him.

Luke Castellan—her greatest love, her most devastating wound. In the chaos of war, among shattered dreams and brutal betrayals, Kiara fought beside him, with him, and sometimes, against him. Through every sacrifice, every loss, a sliver of them remained, haunting, flickering in the dark. Yet, the war was a merciless thing, and both of them knew—deep in the marrow of their bones—that nothing was sacred, not even the love they had fought so hard to preserve.

Monsters, demigods, vampires, and ancient gods sought to break her, shape her, or bend her to their will. But Kiara was never a pawn. She was the burning light that scorched the dark, the magic of the night that whispered defiance in the gods' very ears.

But greatness, as always, demanded a toll. And as the war raged on, as destiny stole more from her than she ever thought she could bear, Kiara learned a truth that would haunt her until her last breath: not every battle is won with strength. Some can only be won through the quiet, aching sacrifice of everything you are.
