A long long time ago during The Cosmic Void Era, before the fracturing of the singularity and the dawn of time. About 360,000 years ago, an astronomical catastrophe transpired—an event that would echo through the ages and come to be known as The 1st Vital Necro War. When an ancient dark entity known as The Arch Devil, cunning and destructive in it's nature unleashed havoc when he opened "The Black Gate". A rift in the fabric of time and space that connects The Mortal Plane to The Abyssal Plane. Thus ushering in the age of ruin, forever condemning the perishable worlds to all of their mortal woes. Bringing about endless on going war, corruption and devastation. Suffering whether wrought by their own transgressions or the propagations of The Maō (魔王), The Arch Demons (鬼), The Evil Spirits (悪霊) and The Semi Devils (悪魔). Thereby ensuing war amongst The Heavens, as the Arch Angels (天使) rose to the challenge to battle the invasive parasitic monsters in order to restore balance and harmony.
