AN: So I don't have to write it every chapter this disclaimer is for the whole story.

I do not own, no matter how much I wish, Sailor Moon or Harry Potter. They belong to their creators.

Also, I really, REALLY, would like reviews! Flames are even welcome. If there is anything in correct about Harry Potter or Sailor Moon, then please tell me so that way I can fix it.

Thank you

Prologue

The date was July 31, 1980. A tall man, with black hair and glasses, paced back and forth in the hospitals waiting, nervously awaiting the birth of his child.

"Mr. Potter," A plump woman in a nurses uniform came into the room, making all the men waiting for news on their wife's stand up, but hearing that it wasn't their name being called sit down with a sigh. "I am pleased to inform you, your wife is doing fine, and that you may go in now."

"Thank You." James Potter left the waiting room, leaving the pacing for another man to continue on doing. He walked down the like pink and maroon colored walls to the room where his wife, and their child awaited him.

When James stepped into the room he noticed his wife on the birthing bed. Her face drenched in sweat from hours of child labor, making it so her auburn hair stuck to the sides of her face. "James, I'd like you to meet your new son. I would like to call him Harry." Lily said, holding a blue blanket with their new baby boy.

"And your new daughter," said a nurse who had just turned around holding a pink bundled blanket, that was his daughter. "Here you go, Mr. Potter. Support her head now. That's good."

James took his daughter from the nurse, looking into his little girls, big, blue eyes. " Well now isn't this a surprise." James stated more as a fact then a question. He was quite shocked. In all the sonograms, it showed that they had one child. Never did it show that they would have twins. "What should we name her?"

As he spoke, the room started to fill up with a purple smoke; a tall girl with green hair down to the back of her knees appeared as the smoke disappeared. She wore a tight, white bodice, with a dark green, almost black, skirt, and bow upon her chest.

"Hello. My name is Sailor Pluto, guardian of the gates of time."

"Can we help you?" said Lily

"I am here to tell you about your daughters past and future. Her name is Serenity, daughter of the Queen Selenity. She lived on the moon, in the moon kingdom, in the age of the Silver Millennium. When she got older, the moon was attacked and she and her friends ended up dying. Her mother, Queen Selenity, took the silver crystal and sent them to earth in the future so that way they could have another chance at life."

"Not to sound rude but, what do you want?" asked James.

"I am here to take her from you so that her destiny can be for filled. She will be needed in a couple of years when she is older." Sorrow filled Pluto's eyes, for she truly did not want to take her Princess away from her parents but she had and Lily both had on a confused expression. James looked down at her daughter. "So, you are going to take our daughter away from her family?"

Pluto took a deep breath and prayed to the Goddess Selene that she was doing the right thing. "I can give you three months with her but nothing more. If I let her stay with you longer it could corrupt the time line and destroy the future." Lily started crying. "Goodbye, I will see you in three months." With that, the room filled with purple smoke again, and then she was gone as quick as she had appeared.

"She's gone."

Three Months Later

"Hey James, do you think that you could get me a bottle for Serenity while I go change Harry?" asked Lily.

Just as she finished asking, the room filled with a purple smoke, and Sailor Pluto appeared.

"Oh no. No. Sailor Pluto, it's too early. You can't take our baby girl. We have only just gotten to know her, when you now come and say you have to take her a way. Please can't you find someone else full fill the destiny placed upon Serenity? Please don't take her away!" Cried Lily.

"I am sorry Lily and James, but I have no choice. I need to take Serenity, but don't worry Harry and Serenity will meet again. Now you must say goodbye so we can get going. I will be waiting right here so you can go get her and say goodbye."

Lily and James walked slowly back up to the nursery, where Harry and Serenity slept. Lily ran over to Serenity's crib, picked her up and turned towards James. Silent tears shaking her form as they fell out of her emerald eyes. "Hello, my sweets. I am sorry but you must go with Sailor Pluto so you can for fill your destiny, don't worry, we shall meet again."She turned and handed Serenity to James. Looking into his eyes you could unshed tears filling his eyes. "My Moonbeam, I am going to miss you. Just remember, I love you, and as your mother said don't fear for we shall meet again."

They walked down the stairs with James still holding Serenity in one arm while Lily held on for dear life onto his other, heading into the hallway were Sailor Pluto a waited for them to arrive.

"I am sorry for doing this to you. If I could I wouldn't do it. If it may help, Dumbledore said that you could write some letters to him for her to have in the future." said a sad Pluto, for she new what laid ahead. "Goodbye James, Goodbye Lily, and Goodbye Harry. Good luck to you all." And with that she was gone.

"Lily, it will be ok. We will be seeing are little girl again. Lets go get Harry and write those letters to Serenity for Dumbledore to give her in the future." James said while trying to comfort his distressed wife, as she cries against his chest.
