From a certain standpoint, it was impossible for anyone to ignore the existence of the God of Holy Light. That was because he was by far the strongest Main God in existence. It could even be said that he was the main reason why the Order and Chaos Faction still maintained their balance of power despite the Chaos Faction being overall more powerful. It was an indisputable fact that nobody would deny: the God of Holy Light was the most powerful existence in the world.
It seemed inconceivable how a Main God who was only slightly under 2,000 years old managed to reach the point where he far surpassed the power level of far more ancient existences. However, it could be understood if you analyzed just how far widespread belief in the Holy Light had become.
