In this "Age of Lamenting Light," where life itself is fuel, light is the original sin.
The eternal daylight that sustains the floating heavenly kingdom of Radiant City is powered not by cold machines, but by countless souls drained dry. This is an age in which life has been turned entirely into a commodity. Every inch of splendor forged from "life lumens" stands upon mountains of bones. The most dazzling civilization is also the largest graveyard.
You will become Yanuo, a "worm" from the Abyssal District. From the most wretched dust, you will kindle the forbidden flame of vengeance with hatred and roar at the empire that devoured your sister.
You will become Lirian, the blade of imperial order, an elite officer trapped in the cage of heaven. When she uncovers the truth of the living sacrifices behind the empire's "prosperity" with her own hands, the faith she has always held fast to will come crashing down.
You will also plunge into the mental depths of Finn, a memory hunter, and be forced to flee for your life amid the hellish scenes dredged up from within. The truth burning in your hands is his only weapon, and the brand that will seal his doom.
You will take the trembling hands of Ilari, a "soul anchorer," and watch as she turns her power to heal souls into the sharpest of weapons. Driven to the brink, she will drag thugs into a hell forged from their deepest fears and ignite the flames of rebellion among the oppressed.
When avengers, betrayers, fugitives, and rebels are drawn together by fate; when the heart-rending question, "Is my sister's life worth even one second of light from a 'lumen core' in your brother's body?" pierces the disguises of every social class, the gears of the story will finally begin to spin into a frenzy.
When the great fire has consumed hell, who will stand atop the ashes: the enemy, or the one and only ally?
