Lilia, the daughter of a vampire lord, possesses an uncontrollable primordial ancestor bloodline. To save her powerless father, she sets out on a journey to collect three keys — Blood, Fang and Light — to open the Northern Sanctuary.
She endures successive calamities: the wolf clan’s sacred spring is sabotaged in a frame-up, demonic beasts massacre border villages near the Holy Court, and her pure-blood elder cousin repeatedly lays deadly traps for her. With compassion and fortitude, she defuses thousand-year-old racial conflicts, earning the voluntary recognition of the three keys.
When the residual souls of the three ancestral elders denounce her together, claiming her half-blood status makes her unworthy, countless commoners step forward to shield her.
The ultimate truth is revealed: the original primal ancestor was also a half-blood. Empowered by the Ancestor’s Heart, Lilia fully awakens her bloodline. She defeats the evil ancient progenitor, ends the universal catastrophe, and becomes the covenant heir honored by all three races. Yet high in the sky, a brand-new rift quietly opens, hinting at an impending new crisis.
