Tales Of The Accidental God

It was said that before the Primal God came into existence, there was a being, created from the purest form of dark energy. This being was the embodiment of chaos and destruction! This being had many names, Darkness, Evil, Destroyer, Universe Ender... to name a few. But the one widely used was the Accidental God!
But after the Primal God came into existence, he created the universe and fearing for its safety, from the influence of the Accidental God, created powerful warriors known as the Sentinial Soldier. With his Sentinial army, the Primal God defeated and imprisoned the Accidental God! But that was never the case, as the Accidental God had already escaped and made his way into the universe, forever haunting it with chaos!
