The Void's Will

On Earth, During the Year 2150, a shockwave was heard throughout the world and the next day strange creatures started to invade earth. Both beasts and intelligent creatures plotted their take over of the earth. These creatures had powers way beyond any gun can affect and so the Humans were pushed back. But a sliver of hope was carried when a voice was heard throughout the world as time seemed to stop"Humans, I will give you my Heaven's Will and you will train in my world for 500 years. You will then return to this world with the power to protect your planet." But one boy, who was the only survivor in his village that was attacked by the invaders. Was instead summoned into the empty darkness and given the Void Elemental Body and 3 techniques.
