A mysterious power has taken over the land, all new species of pokémon have disappeared and the only one who can save them is a stranger with dark powers.
Prologue: The beginning
"Abra, psychic," Called Sabrina.
White light filled the room and concentrated in a ball around Gengar. Agatha watched as her last pokémon fainted, ever since she had beaten Ash and Lance to become league champion, she had thought she was invincible, now Sabrina had proved that she was not.
"Con-" Agatha choked and coughed, Sabrina started forward in concern. Agatha fell to the floor and Sabrina screamed; Agatha had been her role model, stiff and unbreakable, never seeming to age.
Agatha stood up again; her eyes looked to Sabrina, but seemed to see straight through her.
"It is beginning," She said in a trance like state, "Three years from now, the land shall be thrown into turmoil, a power shall rise and take control, the world of pokémon shall be split in two: the corrupt, and the rebels. Humans shall develop unnatural powers and the new species shall disappear. A girl from the other world shall have a great power." At this point Ash opened the door and peered through to see what Sabrina had been screaming about. "She shall be recognised by her purple hair, her name is Sabena. Using dark forces, she will battle the power to try and save the world. It is not yet determined who shall win, and who shall lose." Agatha's eyes focussed again, "Congratulations, child, you are the new league champion."
Ash backed out the door again, slightly confused but sure everything was alright.
"You just gave a prophecy…" Said Sabrina cautiously.
"Pardon?" Asked Agatha.
"You said it was beginning, something about a power."
Agatha's eyes shot wide open, "No, it can't be, not now. Not the beginning." She gasped, then she fell to the floor, this time, dead.
