So, prepare for a loooooonnnggg paragraph
Light and Dark are the two fondamental sentient elements of the universe, they were born in the big bang, first there was Light and then Dark was born, the two fought for a very very long time, in the first few million years, until the first star was born, from that day on, they both wanted to make the universe better, but in different ways, the fought and fought until both decided to stop, the collector was born at the same period than Light, but at a different time, same for Mr Void
Both dont come from Light or Dark, Dark and Light were the first sentient beings but weren't the creators of the universe
The CORE was in danger because Dark wanted it, but Light defended it and another few years went away, until the era of Earth then they stopped, and visited Earth, they were amazed, in ancient cultures there humans saw a luminous figure, and called it God, in religions, a luminous figure is seen to create Earth, even if that is wrong, that figure was Light, but they didn't see Dark in the same way, they saw him as the bad side of a man's mind, and Dark was jealous, and instead of helping and looking over the humans, he tried to lure them away from the light, he lured kids in dark caverns and killed them, he lured men and women away from villages and killed them, all in the meantime promising the eternal life, then war struck between the two, Light and Dark fought and fought, the humans helped Light, but some seeing Dark as the true God, they made rituals to help Dark, but it was to no use
Dark was defeated and Light was victorious, both left the Earth and Dark was imprisoned in Dark Matter, and Light was remembered more than Dark, and soon they forgot about him, Light was seen as a God, then when Life and Death were created, from the humans believing in Light as a God and not the real God, they were punished with Death, but also Life was created, he was still a fetus but could still command Light, and he did
From That day, death was sealed and the world was at peace, until now
Thats the backstory
