Long, long ago before the ancestors of humans had even thought to descend from the trees, there waged a horrible war. It was a war of dominance between the earth and sea. The earth split wide open and fire rained from the skies. Magma rushed from the core of the world to create vast landmasses in the sea. The sea itself fought back, waves rose taller than the tallest mountains to flood the newborn islands.
At the very center of this mighty conflict were two creatures so ancient it is unknown whether they were created after the planet of if they had lived as long as the planet itself. The Lord of the Land fought non-stop against the Lord of the Sea. Their conflict lasted centuries and slowly the Land began to win. Continents were formed and shaped. The Sea Lord realized this and used all its power to summon a mighty rainstorm to encompass the entire planet. Thunder roared and lightning arced across the skies and the rain came. It rained for so long that the planet forgot what the sun had looked like but the Sea Lord was unable to control the storm and fight the Land Lord at the same time. It lost control of the mighty storm.
The rainstorm grew far too powerful for either creature to control. The world itself was in danger and it looked like nothing could save it. But then the Lord of the Skies, who had refused to participate in the struggle between the land and the sea, awoke. Seeing the peril that its world faced the Sky Lord confronted the two warring ancients. In the presence of the Sky Lord the Lords of the Land and Sea cowered and halted their fighting. The Sky Lord then put them to sleep deep within the planet and sealed their power away in two orbs. These two orbs the Sky Lord placed in the care of the servants of the Lords. The orb of the Earth was given to those who fought for the Lord of the land and likewise the orb of the Sea was given to the creatures that fought alongside the Lord of the Sea. That done the mighty Sky Lord returned to its palace in the skies and resumed its endless slumber.
In the wake of the Sky Lord the storm dispersed and sun streamed down on the world. The seas calmed and receded, the land rose and began to team with life. Millennia passed. When humans began to emerge they were greeted by the descendents of the servants of the mighty Lords. These diverse and fascinating creatures came to be called Pokemon.
These creatures where here before us, and chances are they will be here long after us. It is important to remember to that they are the original inhabitants of this world and it was for them that the planet was formed. All those that take up the mantle of Pokemon trainer should keep this in mind and always treat their partners with the utmost of respect.
