A/N: Some of it's mine. Most of its J. K. Rowling's.
Azkaban
Jadis woke up in a dark, dank cell. It had a cold cement floor and a barred window. There were groans and shouts of misery all around her and it smelled like something had died in there. Something crawled across the floor and Jadis flung an arm at it, trying to move it with her telekinesis. It didn't work. She tried to conjure wind, rain, thunder, anything, but nothing happened. She concluded that the shot they had given her had taken her powers. A dementor glided past the door and she transported back in time, into a memory. To the night her mother was murdered.
Flashback:
Jadis followed her mother past the garden. A dark figure came out of the shadows and pointed a wand at her.
"Surprised to see me, Cassandra?" snarled a deep voice.
"Not at all, Lucius." Her mother replied.
"I told you I'd come for you. You rejected me for Severus. The slimy git! The Dark Lord's favorite. You always were after power." He snarled.
Her mother made a movement toward her wand but Lucius shouted, "Avada Kedavra!" Jadis ran for screaming.
"Mum! Mum!" Jadis fell beside her mother and cried. She looked up to see the blond man looking down on her. He stooped down and placed his hand on her cheek. She flinched.
"I'd kill you right now if I didn't believe the Dark Lord would rise again. I'd kill you right now if you weren't a part of the prophecy and he had plans for you." he said quietly.
And then he was gone, leaving Jadis to cry.
End Flashback.
Jadis woke up in a revelation. She had never remembered that much. What prophecy? What plans? She wondered. She looked around to see two trays in her cell, so she imagined it had been two days since she had lost consciousness. She stood and stretched, trying to be able to wake herself up.
"So sleeping beauty awakens." Came a soft voice from the front of her cell.
She jumped and turned towards the voice. Lucius Malfoy stood in the shadows.
"What do you want?" she growled at him.
He walked towards her and stood in front of her.
"Is that any way to talk to your rescuer?" he asked.
"I'd rather rot here than let you help me out." She spit out.
His gloved hand grasped her chin hard. She winced in pain. The other hand that held his cane/wand came up to her cheek. The snake fangs were pressed into her cheek and she knew that it would leave a mark.
"You remembered the part about the prophecy and you wonder about it. You come with me and I can tell you everything. The Dark Lord will tell you everything." He said, with his face not an inch from hers.
"I'll go with you," she said, "If you either get out of my face or take a breath refreshing potion because your breath is rank."
He threw her onto the floor and walked to the cell door. She was laughing as she got up and walked behind him.
"So I'm off the hook? They're letting me go?" she asked as they walked out of the prison.
"My financial influence with the Ministry helped." He said as he handed her a vial. She eyed it suspiciously. "It will give you back your powers. And here is your wand." He said, handing it to her.
She downed the potion and put her wand into her dirty robes.
"Thank you. I don't suppose you brought me some clean clothes?" she asked.
"No, now take my arm so that we can get off of this rock." He growled, holding his arm out to her.
She took it and they were transported inside a Manor. Jadis recognized it as Malfoy Manor.
"How wonderful! Our Queen has decided to grace us with her presence." Voldemort hissed as he came into the room.
Lucius bowed his head respectfully and Jadis barley jerked her head downward.
"Now that you're out of Azkaban, I need to inform you of some things. Come." He said and he left the room. Jadis followed him into a sitting room and sat down when he did.
"The prophecy," he said, "Is about you. Which ever side you chose in the second war, will be the side that wins. If you're on my side, which you are, I will kill Potter and we shall win. That's it."
She looked at her hands. "So that's the only reason I'm alive. Why did he kill my mother?"
"He was rejected. She chose Severus over him and he was extremely upset." Voldemort said.
"Hell hath no fury like a man scorned." She muttered and Voldemort chuckled.
"Too true. Now your father should be here to escort you back to school." Voldemort said and he left.
At the same moment, Jadis's father came through the door and pulled her into a hug.
"Thank goodness you're safe." He said.
"Of course I'm safe." She said and then yawned.
"Let's get you back to the school." He said and they left by Floo Powder.
Jadis bid her father goodnight and went to the Gryffindor Common Room. She was immediately ambushed but she just pushed her way up to her dormitory. She took a long bubble bath and went to sleep, curled up with Artruso.
