In the beginning, there was chaos, a swirling maelstrom of pure raw power over aeons the energies of chaos begin to form wills and devour each other. The only two left were the energies of life and death. The last clash of opposing energies shook the foundations of reality and birthed the three realms of life, death, and a mixture of the two existences. This new realm was made of non-sentient energy that rivalled the power of primordial chaos giving form to both the power of life and certainty of death. Life and death now bound to their realms created avatars from fractions of their power to exert their will over existence.
Death only needed two Fate to watch over the destinies of sentient life and Absolute who cut the stings of fate when their time had ended. The realm of death was sustained by the souls of sentient life that passed through.
Life created six avatars that gave life to existence and dimensions full of sentient life bloomed. Countless of creation, Gyaan of knowledge, Agua of the weather and rejuvenation, Raashi of light and healing, Luciel of life and birth. Thousands of apostles gathered under these avatars and the power and strength of life grew. Almost like an act of disdain for death, the sixth avatar was Thanatos of rebirth and undeath a direct challenge and threat to the stability of the realm of death.
However, ages passed with little to no direct conflict between life and death until suddenly life's apostles wielding the powers gifted to them by the avatars defied their destiny rendering their strings of fate unable to be cut by Absolute fearing the destruction of its realm death poured its power into a fragment and sent it smashing through the boundaries of the realms and into existence to hunt down and destroy those poor dammed fools who dared to defy death.
