Xix, an undead soldier, sets out to kill Nex, the immortal ruler of the realm of Chaos, over a wrong done to him long ago: before he took the throne, Nex was the human Jae Hyuk. This direct sequel to Immortal Regis unfolds inside Nex's court, where political factions maneuver against each other even as Xix plots his own path to the throne room. Between the nobles' schemes and Xix's repeated attempts on Nex's life, the two are pulled into a rivalry neither can walk away from.
