The Darker Family
From the dawn of time, the boundary between Heaven and Hell had been clearly fined.
Once every thousand years, the Day of Judgement - the day when supreme justice is carried out, when the souls of mortals are judged, and when the order of the world is forever altered - takes place.
The gates of Heaven always remain open for righteous souls, those who hold unwavering faith in the light. Meanwhile, sinners must pay the price for their crimes, cast into the depths of Hell, whether they want to deny or escaped from the truth.
However, God is merciful to those who sincerely repent and strive to refairn from committing forbidden acts. They will be considered for absolution in the next Day of Judgement.
Yet, it's difficult to abandon cruelty when it has seeped into one's very blood. From desperate attempts to escape Hell to uprisings in the mortal realm and even in Heaven, chaos was inevitable.
Then they appeared - the first demons born from Hell - who made the choice to fight along side Heaven.
And, of course, there were conditions.
They crush the rebels, asserted dominance over them and gradually became the ruler of Hell.
They came to be know as a family of fierce, determined and powerful Hellborn - yet ones who still retained their conscience - the Darker Family.
