Sun & Moon: Nichigetsu - Prologue
Centuries ago, the Gods Gaia and Uranos were the ones that created the world.
These ancient beings never aged and still exist. However, humanity did not obey all of their commands and went against the will of the ones that created them. And then, the war started. A war that was promised to destroy and wipe out all life forms from the face of the earth.
This destruction was led by The Angel, a God of darkness that was born from all the hate and chaos in the world.
The Four Gods of North, East, South, and West fused their essences to seal away The Angel but paid the price by being sealed along with the Angel.
They were all sealed away in a magical book known as The Book of Moon. There very powers lies suppressed and unknown in the Book of Moon.
Gaia and Uranos however were not sealed away, The Book of Moon stated that the ancient war would repeat itself unless the Child of Destiny comes forth and bring justice to the world. The Child of Destiny remains unfound even to this day but hope is not lost.
