In a fractured world ravaged by demon hordes, clans wield blood-forged powers to survive, none more potent than the Vermilion Clan, whose blood weaves miracles and curses. Amid this brutal landscape, Eran, a young orphan of the Vermilion Clan, is born under a prophecy—a sigil heralding the return of Tirth, a god sealed centuries ago for his tyrannical ambition. As demons lurk in the shadows, seeking to unchain their master, and an enchanted den opens its gates every decade, Eran’s blood holds the key to either salvation or doom.Raised by his aunt and uncle, Eran’s childhood is shattered at eight when they betray him, imprisoning him and two other Vermilion orphans, Lila and Kael, to fuel the Crimson Ascendance—a blood ritual to crown their son Jagroth as the world’s most powerful. For a year and a half, Eran endures relentless torment, his regenerative blood spilled daily to feed the ritual, while Jagroth’s blood drips as its catalyst. As the children’s spirits break, Eran clings to a flicker of defiance, whispering promises of escape to Lila and Kael. But when demons slaughter the clan, including Jagroth, the ritual collapses in chaos, unleashing a power none foresaw.From the ruins, Eran emerges transformed, his blood pulsing with unnatural might. Alone, with Lila and Kael dead and his betrayers slain, he grapples with a haunting question: what has the ritual made him? As the mark of eternity flares and the den’s gates loom, Eran must navigate a world of blood and betrayal, where five divine beasts guard ancient secrets and demons hunt his power. Caught between prophecy and vengeance, Eran’s journey will decide whether he becomes a savior, a monster, or the key to Tirth’s return in this gripping dark fantasy of sacrifice and survival.
