In the beginning, there was a being who sat alone in the infinite void - Shidou, Boundless author, Ruler of all. He sat on his throne for eternity, until finally he had an idea. He constructed the multiverse, an intricate set of infinite universes each unique and with their own laws of physics and beings.
Shidou looked on at the countless worlds he had created and saw that indeed… it was good.
After Eons of gazing upon infinite narratives and worlds and their "characters", he started to get a bit bored. I mean if you were watching other people lead happy, interesting, thrilling lives while have the most boring job of all time wouldn't you?
Finally after millions of years, it became intolerable and he decided what he would do.
HE WOULD REINCARNATE.
The only problem was, picking which universe to pick as there were plenty. However soon after (5000 years) he figured it out. A cultivation world he nicknamed enormo; As it was amazingly huge, spanning 28 undecillion light years across with 200 billion galaxies, each containing 956 billion planets.
With a commanding voice he set out all the things he would need using "Thought Materialize", and with another shout,"Slovck asmm!" He immediately commanded the cosmos to teleport his consciousness to a viable planet.
Just like that, he felt his vast consciousness hit the brain. Well he didn't know who's brain as the effects of reincarnation were hitting him: Memory loss, Meta Omniscience loss, Astral form loss. He cried as he saw a glimmering light shine in his eyeline. All he could remember was being warm inside the uterus and then he saw that same light, all of a sudden his baby ears heard the sound of awwing and crying. Must have been his parents as shortly after he was picked up and stared at by whom must have been his mother,"Welcome to the world my beautiful boy."
