Ages past, the Gods blessed the Earth with magic… Deeply revered, beast, as well as man, flocked to their feet in worship. As time past, man's belief selfishly swayed onto the path of sin. Naturally, wars were frequent and never-ending… peace, became memory; but the greatest threat had yet to reveal itself. The Devils they turned to, sought only the destruction of man, so they released a mutagen unique to the underworld, called the Enox syndrome... Only targeting those with mona, it transformed the weak willed and easily corrupted into formidable, mindless, flesh eating monsters with super-natural forms and abilities.

These creatures are called Enox…Once upon a time, disaster struck, as large portion of these abominations emerged from the shadows all across the globe in unison. Half the magic population was eliminated in almost a single night... Alliances were forged, and the Yeagers were born. Top tier warrior mages who shifted the tide of war. Thanks to their efforts, the Enox were driven back into the shadows where they are now being hunted. Current generations are only left stories to be told as the war wages on. Since they continue to lurk in the shadows, the world needs Yeagers, if humanity is to ever survive... Guild Masters would build schools, known as Magical institution. Created strictly for nurturing ordinary individuals into ideal warriors.

The war prolonged into the 20th century, in a time when magic is widely uncommon. The rarity was due to the malicious attraction the virus has towards magic, and it's share potency against it. This led to the overpopulation of the unpowered masses, who mostly went unbothered throughout the endeavor… but nothing lasts forever... Those capable of using magic, are immediately scouted to become a Yeager, but due to the undeniably low survival rate of the occupation, more and more people chose to neglect the mystic arts. Countless pose as potential victims for the darkness, and few are able to fight against it.
