“Nyl! Please let me train!”
“You should call me Father, and why do you need to train?”
“But you are not my Father, you are my step father.”
“That still does not answer my question!”
“Please! I have no reason, but give me a reason why not.”
“Hmmm. Fine, but in return you must start to behave, I have a fiancé who thinks you are an angel but has never met you.”
“Who?”
“You shall see soon enough, she moves in tomorrow.”
“Tomorrow? So soon?”
“Enough talking, you can go start training, shoo!”
“Ampèreheure ! POUSSE ! POUSSE ! POUSSE ! Non, aucun non aucun non. Ce n'est pas la manière d'agir, essai juste encore et si vous échouez l'essai encore.” She shouted in French as she missed the punch bag. It meant “Ah! SHOOT! SHOOT! SHOOT! No, no no no no. This is not the way to act, just try again and if you fail just try again.” She was not supposed to train, she was a princess. She was Princess Alexzandreh. Her mother divorced and got remarried to Nyl and shortly after, died. Rumor was, she was poisoned by Nyl, but they never figured it out. She believes Nyl did it. Nyl did not love her, he thought if he married her he would become king, but the rules don’t work that way. But when he poisoned her he did not realize the princess would be in his care. He would not kill the princess, if he did, people would start to suspect him of the crime. She continued punching, kicking, and lifting weights. She ended up training until evening. Finally she went to bed.
“Good morning Nyl.”
“Good morning, have you met my wife?”
“No, not yet.”
“I will show her to you, follow me.” He walked off and she followed.
“What is her name?”
“Her name is Kempria, she is in this next room. You can go in alone, behave your best!” She walked into the room where a woman stood.
“Hello, you must be Kempria?”
“Yes, I am. And who are you?”
“I am Princess Alexzandreh, you can call me Alex.”
“Oh! I have heard much about you! Very glad to meet you Alex.” As Kempria shouted, Alex thought the woman looked familiar. Kempria’s top canine teeth looked more like fangs. She thought about who this woman could be, and then she knew exactly who she was!
“I have to go!”
“Not going to stay for tea?”
“I have to go.”
“Well, bye.”
“Bye.” She ran off to the library, grabbed a book, and started flipping through the pages. Finally she found a picture with text above it saying: The Vampire Queen.
“The Vampire Queen. My new step mother is The Vampire Queen?” She whispered to herself.
