A World Reborn - Prologue
Humans. A violent race. For centuries they warred against each other, for almost any reason. Territory, resources, or grudges against each other. As they grew, so did their capacity for war, creating more and more violent weapons, until they created the ultimate weapon; the nuclear missile. It could wipe out an entire city and everything around it. The worst part was the radiation it could unleash destroying all life in it's blast radius and prevent it from ever growing back.
Many countries agreed never to use such a destructive weapon for fear of annihilating each other. But time passed and their anger and aggression grew, until finally, the agreement was ignored and nuclear war was declared. Countries unleased their greatest weapons at each other. But the two most powerful nations, America and Russia, had the most enemies and missiles and fired theirs, not just at each other, but at everyone else, too
The war lasted only two days but the end result was what everyone had tried to avoid; planetary devastation. Nuclear fallout spread throughout the planet, rendering it almost lifeless in a matter of weeks. Humans couldn't survive the radiation and died, along with all plant and animal life. And with that, the planet died, damaged beyond all repair.
Or so it seemed.
When the dust cleared, an unlikely being emerged from the rubble of what was once his house. He was not Human and hadn't been for some time. He appeared before a small group of survivors from his small town which had been caught at the edge of the blast, but no less damaged. Realizing the world had ended, he sought to build a new one from the ashes.
He introduced himself to the surviving Humans as Myu, a blue Mew. With his powers of creation and life he created a mountain that he shaped as a tree. From there, he spread his powers over the remains of his city, creating new life according to his design, and dispelled the radiation that would have killed his new life. He gave all Humans the choice to start over and used his powers of transformation to turn them into new beings in his own image. This new race of beings called themselves Pokémon and thanked Myu for a second chance.
The Pokémon lived in the tree-shaped mountain, which they named the Tree of Beginning, as it was the beginning of their new world. The Tree provided shelter, a spring provided water, and Myu created plants that produced berries for food. Myu also taught the Pokémon how to peacefully resolve their conflicts and disagreements, and at times, intervened himself when necessary.
But Myu couldn't always be there for them, as he had other duties to fulfil. His goal was to spread his power over the entire world so it could thrive again. But that would take years, maybe centuries to do. Myu also had a charge to take care of. A Manaphy, named Hope, who had survived the devastation and called him father.
Twenty years passed and the Pokémon home had grown, now encompassing more than what used to be their town. The Pokémon also had new children, to whom they passed the memory of their old world too, and taught Myu's philosophy of peaceful resolution.
And as for the Humans, the Pokémon believed them to be all dead, killed by their own foolishness, and gone for good. No one had seen a Human since their world ended, and they were content to let it stay that way. But one day, that all changed…
