Deep beneath the earth, there existed a world filled with dark energy.
It was a realm known as the Demon World.
More than six thousand long years had passed.
There had once been many kinds of beings there.
Those who had gone mad.
Those who had taken twisted and inhuman forms.
Those who had become nothing more than black shapeless masses.
One by one, as time moved on, they crumbled and disappeared.
They had existed only to fulfill one purpose, that's to protect.
They had endured through ages, stubborn and unwavering, for that single duty.
At last, only one remained.
And within that last being, a faint trace of human consciousness still lingered.
Once, long ago, this being had been a man that was one known as the greatest sorcerer the world had ever known.
His eyes had melted away, his fingers and limbs had long since blackened and crumbled, leaving him without a human shape.
Yet even so, through the centuries, his will alone had kept him barely human.
