Taking the Forgotten Abyss as the starting point, Isolde opens up the Chaos Faith, and unites with eight core believers including Layton and Karen. From surviving the remaining souls to taking charge of the Chaos Cult, they tear apart the hypocritical rule of the Holy Light Church along the way, expose the truth about the false god of Holy Light stealing the power of the ancient gods, and finally reach a balance between human reason and the instinct of the ancient gods. Use chaos to protect the mortal world and establish a fantasy epic of a new order of free faith.
