There was one thing everyone knew about the Greeks and it was that they're a tough mythology however about 500 years ago they started to fall and since then they've been underestimated by other mythologies. That was until one of the Gods from the Greek world strikes a deal and births a child with potential to completely shift the balance of the world

Cosmic Crystal, the very source of a high level energy, Cosmic Energy, which was used to nurture a high level universe. What will happen if this Cosmic Crystal from a high level universe, finds its way to a low level universe with an energy close to none? What will happen if this cosmic crystal give birth to a man with his entire body made out of cosmic energy? Simple, that man can command, bend, and destroy the very laws, rules, and restrictions of the very universe itself. Bending reality is as easy as walking.

In the beginning, there was one being: this being had an unlimited amount of power that it could not use. So it wandered around nothingness searching endlessly for something or someone else until it decided that it had enough and so it destroyed its own existence not knowing that its existence had only just begun.
