The Fourteenth Dawn: The Demon Within (A Seventeen Supernatural Fanfiction)

Samuel Arredondo Kim once lived a peaceful life in the quiet town of Gyeongmuri, where humans blessed with supernatural gifts-the Byeonsingyeon -lived in harmony. Born into a family of powerful psychics, Samuel's days were filled with laughter, meditation, and the warmth of his parents and his younger sister, Ximena. But that peace shattered one blood-soaked night when an unknown demon attacked their home, killing his parents and corrupting Ximena's soul, turning her into the very creature they once hunted.

Heartbroken but determined, Samuel sets out to save what remains of his family. His only hope lies in the hands of the Thirteen Gwanja of Gyeongmuri -a legendary group of demon executioners known for their unmatched power, and each carrying their own scars from the endless war against demons.

But when Samuel pleads for help, the Gwanja are divided-half see a boy desperate to save his sister, while the others see a dangerous demon that must be slain. Caught between mercy and duty, Samuel joins the Gwanja's hunt, fighting alongside them while uncovering their painful histories, unspoken bonds, and the true nature of the demon who destroyed his family.

As the line between human and monster begins to blur, Samuel must face the ultimate question:
Can love redeem what darkness has claimed or must it be destroyed to protect the world?
