A battle between the embodiment of death and a despotic imp whos ambition will put the world at risk causes chaos for life upon the earths surface.
Due to this battle, true death no longer occurs, and the souls remain within the corpses of those who lost their lives. Creating demons who walk the earth, long after the bodies of their hosts expire.
However, the embodiment of death seeks to reverse this mess created by the imp, by seeking him out in the mortal plane where he had fled, and forcing him to subdue himself with the help of a dead mothers soul.
Little does the embodiment of death, or the imp know... that a mother who loves her child, cares not for the business of others.
