In ancient times, Luminus was a unified and harmonious empire, where dragons soared across the sky and magic flowed freely. However, this tranquility was shattered when a Dark God sought to exploit the power of the monsters for his own sinister purposes. Alongside this malevolent deity, mysterious stones known as the Dark Stones descended from the heavens, bringing with them disaster and chaos.

The Dark God also dispatched his servants to further the spread of darkness. These included the Demon King, who established himself in the Demon Tower; the Ork Chief, residing in the Ork Maze; the Baroness, who took control of the Spider Dungeon; Azrael, found in the Catacombs of the Devil; Beran-Setaou, located in the Dragon's Lair; and the Satanic Butcher, stationed in the Enigma Temple. These servants wreaked havoc across the land, intensifying the strife and destruction.
