14) The Secret of the Old Chateau
Quite some time before the events of Pokemon Diamond and Pearl, a man and his wife lived in the Old Chateau. They had a daughter and lived a quiet and peaceful life. There were several butlers working in the Old Chateau. One of them was called Charon. He had a knack for messing around with electrical equipment in the mansion.

One day, he went into the basement of the mansion to fix an electrical problem from a recent thunderstorm. As Charon was fixing the problem in the basement, he found a peculiar looking object in an unused washing machine. He messed around with the object which he called a "motor". After a couple of days, the motor came to life. Charon realized this certainly was not a motor, but a new species of Pokemon. He called the Pokemon "Rotom" and adopted it as his own.
Several weeks, later, the man's daughter was having a problem with his microwave. She called on his favorite butler to fix it, but he couldn't do the job, so he called on Charon to help him. Charon didn't know how to fix a microwave either, but he knew that Rotom could transform into one, so Rotom transformed into a microwave.

Before cooking anything, they decided to test the Rotom microwave. The test went horribly wrong. Flames came bursting out of Rotom's mouth and filled the kitchen with smoke. Charon commanded Rotom to stop, but it couldn't. The smoke was starting to spread throughout all parts of the mansion. There was nothing that can be done except to evacuate. Everyone made it out in time... except for the man's daughter. One of the butlers quickly realized this and went in to find her. The butler eventually found her and realized the girl had been poisoned from the smoke. He searched everywhere in the mansion for medicine. He finally found an Antidote in a trash can, but it was already too late. The butler started choking from the fire and eventually died from suffocation. The girl soon perished from carbon monoxide poisoning.
Rotom felt emotionally depressed following the event, so he confined himself in a television set for the rest of his life.
Charon, realizing the trouble and damage he had caused, ran away from the scene and later worked as a scientist for Team Galactic.
The man's wife was distraught at what had happened so decided to take up Pokemon training. She decided to train with the Ghost-type so she can communicate with her deceased daughter. She later became a Gym Leader in Hearthome City.
The man... he was just as distraught as his wife. He built a mansion just exactly like the Old Chateau... but it just didn't feel right. He returned to the Old Chateau and retrieved a statue from the entrance hall and the bodies of his daughter and the butler. He placed the statue in his office and the interred the bodies in two separate rooms in his new mansion. No one is allowed to enter those two rooms.
The ghosts of the butler and the girl still haunt the Old Chateau to this very day. The butler is still desperately trying to find the Antidote, but he does not know that he will reach the girl in time. As for the girl, she is still waiting for the Antidote in her room, but she does not know if she will live.
