"Ten thousand years ago, our world came to a tragic end. We do not know what happened or why it happened, but we refer to this apocalyptic event as the Great Cataclysm. Whatever the Great Cataclysm was, it caused the planet to stop spinning, and ultimately, one half to burn and the other to freeze. The side that burned, the one facing the sun, became an inhospitable desert. Meanwhile, the side that froze, the one facing away from the sun, became an arctic wasteland. Only narrow strips of land in between the two sides remained habitable. They were close enough to the sun to feel its warmth but far enough away to not cook beneath it. In the present day, civilization has returned to the world, surviving where it can. Ground-types, Rock-types, and Steel-types dominate what is now the Inferno Desert, and Dark-types, Ghost-types, Water-types and Ice-types rule the land now known as the Eternal Tundra. Meanwhile, Grass-types, Bug-types, Poison-types, and even Normal-types have managed to survive in the collection of hamlets, villages, and even prospering cities located in the habitable zones, known colloquially as the Eastern Dawn and the Western Dusk."[/I] - Kulero, the Great Seer

What if one day you woke up and you were a Pokémon? You awaken in a strange new world with new memory of who you are, where you are, or how you got here. All you really know for sure is your name, that you were once human, and that you now inhabit the body of a Pokémon. You do not know it yet, but you are to become one of a handful of champions summoned to this world by the Great Seer. As the Greet Seer will tell you, there is an empire deep below the surface that has uncovered the device that caused the Great Cataclysm ten thousand years ago. The emperor and his generals intend to activate this device and use it to take over the surface world! However, something is missing, something that is stopping them from following through with this plan. Thus, your goal will be to recover both the device and the mysterious key to activating it so that the Great Seer might find a way to harness its power to reverse the effects of the Great Cataclysm, ending a ten thousand year era of darkness!
