Everything is bound to an endless cycle of creation and destruction, since the beginning of times.
However, every end is fated to become the same start, and every start is fated to be the same end.
The end is the destruction of everything, and then the formation of Nothingness; a lifeless space, in complete darkness. From that darkness, the first light, the first being, was formed. Formed from the life of the ones that have fallen in the past.
The being once named itself The First One. Amidst Nothingness, that being feel something coming from inside him, the urge of creation. The Second is born from it.
As time goes by, a third gives birth to a fourth, and so on.
After infinite cycles of death and birth, The First One had another enlightenment, or perhaps it was a selfish whim, the creation of a body for him to use. In the Nothingness, a giant body could be seen.
The Descendants surrounded the strange figure, not knowing that it was actually their father. Using his omnipotence, The First One gave every one of his sons a body.
Time flew once more. Over the cycles, three major changes occurred. The Descendants stopped giving birth, and instead, they started creating something they called galaxies.
With the creation of galaxies, a simple problem arose: Who had the best Universe? The judge chosen was their father, The First One. He was the only one that was still giving birth to Descendants.
For countless cycles, a joyous and peaceful competition was held in the Nothingness. Nevertheless, there were some of the Descendants that never won, or rather, were never chosen as the winner by The First One. For the first time in that cycle, a simple grudge against their own 'incompetence' came into form.
That grudge corrupted their soul. They were blinded by the urge to win, at least once in their lives. Some would win by their effort, and the ones that couldn't win no matter what became insane, completely blind, and corrupted.
The First Separation, is known as the first war and trigger of destruction. The end of a cycle, in other words. The insane Descendants joined hands to kill the others. If they couldn't win fairly, then they just needed to get rid of the ones that win in the first place.
Hundreds of thousands of Omnipotent beings killed each other for countless years, nonstop. Along with their deaths, the galaxies that they created were destroyed.
Even with the First One giving birth to new Descendants, the proportion was simply too big. For every new one, ten would die. It was unbearable. He would wait for them to stop for themselves, or in the worst scenario, intervene. He didn't want to kill his kind at first, so he waited, for a long, long time.
He waited for too long, however. From the war, just three beings were left. He, The Second and The Third.
They made a vow, to prevent another war. The Second and the Third would never kill each other, but The First One would never give birth to a new Descendant. He, and only him, would be able to create new galaxies. The Second and Third would only oversee the said galaxies.
The peace finally returned to Nothingness.
