The world of Pokemon today is a lot different from the world of yesterday. How were Pokemon used when they were first being discovered as partners? What exactly were they being used for in the first place?
The first war of the world began when the humans in the earliest of days began to mistreat Pokemon. The Pokemon themselves revolted, and many species were wiped out. The humans succeeded in keeping the Pokemon at bay, but they paid the price - the Pokemon were mistrusting. They demanded a treaty, and the humans promised that they would be treated justly, as equals. As partners.
The humans and the Pokemon lived in peace for many years, until soon, a tyrannical group called Septus rose into power. It was in the days of the Black Plague, making it easy to influence the weak minds of the common people. They convinced them all that the Plague itself was caused by the dark and evil Pokemon, such as Rattata, Ghastly, and Houndour. They soon banned Dark and Ghost Pokemon, along with Rattata and Raticate.
Some members of Rusei stood up to Septus' tyrannical rule. Calling themselves the Rusei Knights, they tried their best to stop the group's rise to power by keeping the banned Pokemon along with trying to fight off the team.
Many legendary Pokemon noticed their plight, and soon began to take sides. Was a war about to occur? You have the power to change history.
