Millennia into Earth's future, spiritual upheaval reshapes the world's religions, fracturing the barrier between the physical and spiritual realms. Demons and ghouls breach into the mortal world, yet most are quickly resealed by newly emerged faiths—all except the formidable Belial, whose imprisonment demands nothing less than divine angelic power. Thousands of years later, a destitute woman named Ambrosia Brahmin is chosen by God himself for an epic quest, accompanied by an unlikely fellowship: a swordsman, shaman, thief, druid, exorcist, angel, and demon. Meanwhile, the ancient demon sealed within a jar begins breaking free as a manipulated wizard, seduced by false promises of reward, unwittingly works toward its liberation.
