Han Dong awakens as a sentient cell in a parallel realm where the Ancient Ones have risen. Armed with the Prison code's power, he navigates a steam-powered civilization haunted by eldritch horrors, dimensional rifts, and the terrifying Ancient King of the Eternal Night. Beyond the city walls, monstrous entities prowl in shadow. As Destiny's door swings open, five pillars emerge to reshape humanity's future: the Crusaders' might, the Library's knowledge, Control's dominion, Machinery's innovation, and Mysticism's secrets become the foundation of a new evolutionary system.
