A century after humanity's Great Catastrophe, nations have splintered like the feudal states of ancient times. Each country is bounded by its cities and ruled by its great clans. Beast Tamers, superhumans, mutants, and beast-soul masters hold sway. Magical beasts run rampant, nations wage covert wars, and humanity is divided into ranks. The world is chaotic and corrupt. A poor young man steps out of the darkness, carrying a divine space artifact and commanding hundreds upon hundreds of soul beasts. He clears away the fog and brings humanity the dawn.
