To seal the abyss, the century-old demigod Isolda embarks on a quest to reclaim the Twelve Sacred Covenants. Her journey takes her from the power-hungry Duke’s estate, through the fractured Territory of Hawke, all the way to the Northern Citadel wrapped in eternal night. Along the way, her relationship with the Royal Knight Caelen evolves from bitter rivalry to unwavering, life-and-death devotion. Facing a fatal prophecy that dooms Caelen to a horrific death for her sake, he shields her from a fatal blade with his own body. Refusing to yield, Isolda breaks destiny for the very first time—forcibly infusing a Sacred Covenant into her lover's body, bringing him back from the dead with godlike battle prowess. As they uncover the massive conspiracy driving the abyss's rebirth, the duo transforms from slaves of prophecy into masters of their own fate. Renouncing the cold old covenant, Isolda and Caelen march together toward the heart of the abyss. The remaining nine Sacred Covenants will be their ultimate stakes to purge the darkness and bring peace to a chaotic world. Prophecy is not the end—human resolve is the only true variable.
