Synopsis：Branded the useless son of a fading noble house, Caleb has spent his life ignored and dismissed—until the day his beloved sister Elara is about to die, and he tears away his mask. Hidden beneath his weakness is a terrifying secret: he is the reincarnation of the Wraith King, the supreme terror who once ruled the Caelian Empire. As the treacherous Graves family joins forces with the ancient Fiendkin to break a seal that has held for centuries, bloodlines, honor, and the empire itself stand on the brink of ruin. To stop the coming catastrophe, Caleb must rally the feuding Wraithmaster clans, command forbidden spirits like the Twin Reapers, and ascend to the mythical Abyssal Sovereign realm—before everything he loves is swallowed by the abyss.
