After a well-lived life on Earth, Kael never expected anything more than death and the sweet embrace of sleep and darkness.But fate had other plans. He was reborn in another world similar to Earth, where he grew up until he was ten, at which point his memories from his past life were reawakened.He was an old man trapped in a boy's body, but the mixture of the child's memories with his own made him feel more middle-aged than old.A few days later, the world he was in ascended into the realm of war, the battleground of all living beings. Kael was among the few awakened who had the chance to become the ultimate god of existence, based on the orbs of different paths presented before him.Kael was faced with three choices:Orb of ChaosOrb of NothingnessOrb of Void(Choosing any will make you undergo a trial that will change your very existence. Please choose wisely.)While in shock by these options and seriously pondering which one to choose, an unexpected event occurred.(Error detected... A new option has been created)(Be the wielder of the three — Chaos, Void, and Nothingness)(Answer picked by host, transporting...)Kael was in shock as he fell into darkness, with one swirling thought in his mind:“I didn't even pick any.”

One day, the majority of humanity had a collective thought.

‘I wish the world would just collapse.’

And then, that wish came true.

A world only I know of, now I will take it all for myself.There’s no kind soul here willing to share and eat nicely with others.Only the ruthless one who will devour it all alone exists here.
