Prologue

A/N I Don't own Harry Potter or Star Wars, If I did it would have been a much worse story :D

"Ahsoka!" Anakin emerged from the shadows, searching for some unseen threat.

"Ahsoka it's me," Anakin repeated. "You're safe now let's go."

Ahsoka seemed to ignore Anakin for a moment before speaking still facing away from him.

"Are you… proud… of me, Master?" Her voice rang out in the air, with only the sounds of the storm around her it seemed quite, ominous to Anakin.

"What?" Anakin exclaimed, taken aback. "Of course, Snips, of course, I'm proud of you, now let's get out of here."

Thunder crashed in the distance as Anakin kept looking around for some unseen threat.

Raising her head Ahsoka spoke again, this time anger infected her voice.

"He's Right. Right about everything. You must join him!" Turning to face Anakin as she spoke.

Anakin stared in shock, Ahsoka's skin was filled with dark lines, she looked sickly and almost dead, but her eyes. Her, eyes normally vivid blue had turned an ominous yellow.

Her stance changed into something between coy and innocent.

"He only wants what's best for the universe."

"Hey, what's wrong with you?" Anakin bluntly asked.

Ahsoka rolled her eyes. "Always with the criticism, Master." Her voice filled with irritation. "Never really believing in me, trusting me." She began walking, looking like she was going to pace before stopping and turning away. "Well, I don't need you anymore."

"Ahsoka." Anakin began to reach out with his arm "Ahsoka listen to me. He has done something to you. Snap out of it. This isn't you, Ahsoka."

"Isn't it?" The anger in her voice was hard to miss, the sound causing dread to fill Anakin. "I feel more like myself than I ever have." Her voice had taken a different turn now, to Anakin it sounded like insanity had overtaken her. Her voice returned to anger and darkness as she said. "He asked me to give you a message." The words floated ominously in the air. "He said, if you don't join him, he will kill me." She began to giggle.

"I won't let him," Anakin spoke determinedly, not willing to let anything happen to his padawan.

Ahsoka turned to face Anakin once more. "Then you will be Forced to kill me."

Ahsoka lowered her hand to her waist, using the Force to summon her lightsaber to it. Igniting the weapon, she leapt into the air bringing her lightsaber down in a powerful strike.

Anakin reacted fast, igniting his own lightsaber as he blocked and parried her strike. Her assault was furious, Anakin was constantly on the defensive, using his size and strength to push her back or parry or dodge but never counter-attacking.

As their blades locked wants more he shouted. "I don't want to fight you Ahsoka!"

Ahsoka didn't respond instead kicking him in the face as she performed a back handspring away igniting her saber again.

"And now the student will kill the master."

Taking advantage of her distraction, Anakin pulled on the Force summoning his weapon to him as Ahsoka leapt into the air once more. He managed to get the blade ignited just in time to block the attack.

"Getting ahead of yourself aren't you, snips?" he taunted.

"Don't call me that." Ahsoka protested in frustration. "I hate it when you call me that."

Ahsoka made another strike, but Anakin disarmed her, throwing the lightsaber into the air.

Anakin smirked until Ahsoka jumped onto his shoulder before leaping into the air, landing, and catching her lightsaber as she turned, igniting her second lightsaber as well.

"Two Jedi." She smirked as Obi-Wan arrived. "Finally, a challenge." She leapt again, attacking the two Jedi with haste and fury, forcing them to remain on the defensive lest they injure her.

"Any suggestions?" Anakin called out as he pushed Ahsoka back with the Force.

"Yes," Obi-wan replied, his hand reaching into his pouch. "We cut her free." He held out his hand, a dagger forming from a hilt he held.

"What is that?" Anakin asked incredulously.

"It can kill The Son." Was Obi-Wan's reply.

"Ughhh!" Ahsoka's voice had taken on a darker tone, sounding as if both she and The Son were speaking at once. "Where did you get that? Give it to me!" She charged again, fury on her face.

Suddenly two bodies flew through the window behind them. The Son and The Daughter landed a few meters in front of them, interrupting the fight.

"So glad you could make it to our little party Father." He called tauntingly before throwing Force Lightning at Father. Father blocked using the Force, but it began pushing him back.

"You will stop this," Father demanded, straining against the onslaught.

"You are too weak for me, old man." The Son began using his other hand to throw lightning as well. "You mean nothing to me anymore."

The Father tried to push back but was overcome, being thrown backwards by the lightning before falling limp. The Son began to stride towards him, preparing to deal the finishing blow. Lightning thrown from his fingers throwing The Father back again.

"Anakin, now!" Obi-Wan threw the dagger only for Ahsoka to jump and intercept the blade. Landing right next to The Son.

"Everything has transpired, exactly as I planned." The Son gloated.

"You… You showed them the altar?" Father weakly asked.

"I am sorry, Father." The Daughter spoke as she was held up by Obi-Wan. "I didn't know how else to stop him.

The Son ignored his surroundings as he turned to Ahsoka. "Give it to me, child."

Ahsoka turned to look at Anakin and Obi-Wan and smirked.

"Ahsoka, no!" Anakin pleaded.

Ahsoka turned back to The Son and handed him the dagger.

"Thank you," he said swinging the weapon. "Your usefulness has come to an end." He finished his sentence by pressing two fingers to Ahsoka's forehead. She slumped to the group, lifeless, her lightsaber falling from her hand.

"No!" Anakin cried, rushing towards her only to be thrown back by The Son.

The Son turned to the father. "The Jedi have brought me the dagger, and you have brought yourself."

Pausing, The Son began to smile. "Now, Father, you will die." He brought the blade up, preparing for the final strike.

"Father!" The Daughter cried before jumping in front of the powerful downward strike, taking the blade deep into her back.

"Whyyyyy!" The Son cried in anguish, seeing his sister with the blade in her back. Before turning into a large batlike creature and flying away.

Anakin ran to Ahsoka turning her over and seeing the white that used to be her eyes.

Father pulled the dagger out of Daughter's back. "My Daughter," He paused in his grief. "What have I done?"

The Daughter coughed and weakly reached for her Father's hand.

"Do not hate him, Father." She pleaded. "It is his nature."

"No," Father wept. "All has been lost, the balance has been broken. I thought by bringing you here, I would…" He trailed off. "But I have destroyed everything!"

"Can you help her?" Anakin demanded his eyes dull and angry as he gestured to Ahsoka.

"There is no light," Father spoke as if not even hearing Anakin's demand. "The evil has been unleashed, and the Dark Side shall consume her."

"You must help her!" Anakin snapped, desperation filling his eyes.

"I cannot undo what is done." Regret filled Father's voice. "There is no hope."

"Yes, there is!" Anakin shot back. "There is always hope!"

Father looked Anakin in the eyes. "No Chosen One. I am sorry. But she is gone."

Anakin screamed in a primal rage. The wind around him picked up as his anger began to consume him.

"Master." A voice echoed from all around him. "Master please."

Anakin looked up, tears leaking from his eyes. "Ahsoka?" turning he saw a spectral form walking towards him, with each step the figure was unclouded until he saw Ahsoka before him.

"Ahsoka!" Anakin exclaimed relieved. He ran to hug her before passing through her.

"Master I am sorry. But I have to go."

"Ahsoka please don't leave me." Anakin cried, he desperately reached to hold her. "Ahsoka!" He shouted.

"Keep fighting Master, for me." Ahsoka's voice echoed out as her spectral form vanished.

"Nooooo!" Anakin screamed in rage and pain as Obi-Wan leaned down next to him putting his hand on Anakin's shoulder.

Somewhere else, very far away from Mortis. Ahsoka awoke.

"Master?" her voice shook as she took in unfamiliar surroundings. "Master, where are you?"

A voice from behind startled her. "Well I'm not sure about this Master stuff, seems kind of kinky if you ask me.

Turning Ahsoka was shocked to be looking into the most beautiful green eyes she had ever seen.

A/N: So, I was working last night when this idea came to me. I have read a few harry potter stories where Harry ends up in the Star Wars universe for one reason or another, but I haven't seen a bunch where a character ends up on Earth and must stay there for some reason. I mostly knew I wanted to write something where Ahsoka ends up on Earth and decides to help Harry deal with the Triwizard tournament. I couldn't figure out at what point in the clone wars timeline I wanted to take her from but figured I wanted her to have some experience as a Jedi and padawan first. But then how to get her into Harry's universe? I don't want spoilers for anything, so I'll just say I hope you've enjoyed it so far. I know most of this chapter was taken from the show, but it should be more original from here on out.

I do want to say I was inspired to write this by the story: I still haven't found what I'm looking for by Kathryn518. If you like crossover Harry Potter/Star Wars I recommend you read it. I enjoyed it.

This is also my first fanfiction, so all feedback is appreciated.
