Background setting
worldview
The game inherits the world view of the series of novels of Devil Hunter. A disaster happened 1500 years before the novel story happened. The worlds of different dimensions collide, and the worlds are directly connected and penetrate each other. This disaster is called "celestial convergence", which trapped many creatures from different worlds in this world.
For example, ghouls, blood thorns and high-level vampires are all remnants left by the intersection of celestial spheres. These creatures, with their own unique ecology, are remnants of the past. According to fairy tales, people came to this world because their previous world was destroyed.
Human ancestors learned how to control the power of chaos, and the earliest human wizards were born to fight other creatures from different worlds. However, because monsters are scattered everywhere and difficult to beat, magic hunters were born without ordinary people confronting monsters. They are hired by ordinary people to hunt monsters to protect people from the threat of monsters for a living.
