Hello there Cade! As you know, I study the creatures that inhabit the Earth with us- the ones we call Pokemon. Mine is the story of the beginning, and-possibly- the end. I've worked with you since you were just a boy, eager to learn, and now you've grown into one of my most trusted companions. This is why I'm entrusting you with this mission.
Perhaps I should backtrack a little.
It started when I was a boy. The continents had all been devastated by nuclear warfare between the Koreas, America, Japan, China, and India. Only a fraction of the human populace remained- close to two million. 8.1 billion humans had been wiped out by a war that spanned 50 years. They all resided in the remote jungles of Africa, where we built up our community. It was different then- peace flourished, there was no strife or fighting, and we were all one power. That was when the asteroid hit. The asteroid hit northern Africa, and we sent out groups to locate it. What they found would change the course of humanity forever. There were many creatures that we had never seen, all in pairs- like noah's ark. I was part of the first group- only 14. My father was the general, and he wanted me to see. When the first Pokemon- the one we later called Lucario- excited, he explained everything. He located me, the youngest of the group, and...spoke to me. He revealed that his home planet's sun was dying, and so they were sending two of each species of Pokemon to the nearest habitable star system. Ours was the target. They traveled here and saw hope here, and so landed safely. When he revealed this all to me, and I to everyone, Lucario became my companion. I became a Professor on Pokemon, and educated the entire community. From this knowledge, two groups were born- those who wanted to live alongside them, and the small group that wanted to control them. They called themselves Team Rocket.
Team Rocket use Pokemon for their own nefarious purposes. They plan to harness their power and use it to control Earth. This is where you come in. I have studied Pokemon for all my life, and have developed certain tools for you to use. First of all, there is the Pokeball. Use this to capture Pokemon that you can fight alongside. Then, there is the Pokedex- a device you can use to record what types of Pokemon you encounter. These two tools I entrust to you. Fortunately, I was able to launch Pokeballs worldwide, so you can buy them at any Pokemart. In addition to these two tools (placed in the drawer below), I entrust to you a Charmander. This will be your starter Pokemon. Train him well. The rest is up to you. If you are reading this, then I am dead (They will have taken my body), and you must fulfill the mission set forth for you.
This is your mission. if you hope to ever become strong enough to take on Team Rocket's leader, you will need to battle in the Pokemon Gyms and defeat the Champion. The Gym leaders are friends, and will help you and guide you on your journey. Now, go!
