AN: New Story. It will be a crossover soon but I'm still debating what to cross it with. This story will be a 3 part story. One part for pre Hogwarts. One for during Hogwarts. One part for after Catherine Potter's fourth year when something unexpected happens.

AN2: Reviews and Comments are appreciated. Also, I happen to be American so I won't know some of the words used in Britain.

Summary: After Lily and James Potter hear about the prophecy from Dumbledore, the 3 of them came up with a plan. A plan that was for the Greater Good. And, because of their manipulations, a young girl's life will be changed forever. But, nothing ever goes all according to plan.

Disclaimer: I don't own anything related to Harry Potter.

"Are you sure that this is a good idea Professor Dumbledore?" a quiet voice asked.

Three people were standing in a room surrounding a cradle with a sleeping baby inside: a red haired woman with the most stunning green eyes around, a hazel eyed man with untamable dark hair, and an old man whose eyes twinkled like shining stars.

"It needs to be done my dear Lily; it is for the Greater Good after all. And, I remember asking you to call me Albus. After all, you are no longer in school. There's no need to refer to me as Professor anymore." the old man said in his grandfatherly voice.

"Albus is right, Lily flower. We have to do this. It's so our baby can survive." the younger man reasoned with his wife.

"If you say so, James. It just feels wrong doing something like this to a baby." the now identified Lily replied. She was staring intensely at the sleeping baby.

"I'm sure when she grows up, she'll understand. Things will be explained to her and she will know that it was for the Greater Good." Dumbledore's determined voice said.

With a last sigh, Lily agreed. This would make her baby safe and that was the most important thing right now. Right?

With a wave of their wands and a long line of incantations, the deed was done. Dumbledore let out a sigh of his own and turned away from the still sleeping baby. "It is done. I must be going now; Hogwarts cannot go without me for too long."

"We understand Professor." At Dumbledore's look, Lily continued, "You'll always be a Professor to me, sir."

The aged Headmaster let out a soft chuckle, which turned into a frown after a moment of thought. "Yes well, I don't like the idea of leaving you alone. After casting the spells, your magic cores are almost drained."

"Not to worry sir, Sirius is coming soon. He just got Catherine to say "Pa'foo" the other day. Now, he's working on getting her to say "Moony." He and James are having some sort of contest." Lily said with a laugh at the end.

"I can't believe my baby said "Padfoot" before saying "Daddy!" It's not fair!" James whined.

Lily rolled her eyes at how childish her husband could be. Sometimes, she wondered if she had 2 children in the house instead of just 1. "By the way sir, you will be needing our hairs for the potion won't you?"

"Right you are, my dear. I fear my age is catching up to me for me to forget such an important thing." Dumbledore replied.

"Nonsense sir, you have too many things to worry about. Forgetting something every now and then is normal." Lily reassured as she handed him the hairs.

Dumbledore smiled at how the small family was behaving. It was nice to see that they could still laugh after all they have been through. Having a Dark Lord after them constantly would affect even the most cheerful of people. With a round of goodbyes, Dumbledore turned and Apparated away with a small bundle in his arms.

Dumbledore stood in the Potter's house at Godric's Hollow just seconds after the attack. Everything had gone according to plan. Lily and James had done their jobs spectacularly. Voldemort was gone; destroyed by the rebound of his own spell. But Dumbledore knew that it was not over; that his wayward student would come back and terrorize the world again. It was just a matter of time. Even during his Hogwarts years, Voldemort dabbled in the Dark Arts. There was no doubt in his mind that Voldemort had found a way to prolong his life. But, Catherine Potter was the key to everything. She, the prophecy child, will have the power to stop Voldemort once and for all.

The aged Headmaster looked at the baby in his arms. Her face was now marred with a Lightning shaped scar right above her eyebrows. Her cerulean eyes stared confusingly up. The Headmaster frowned a little. Blue eyes would not do. This baby would play an important role in the future. The public needed to identify her with the Potters. Lily had green eyes and James had hazel. Perhaps a spell would fix things.

With a last check over, Dumbledore set the baby down in the crib and Apparated away. Sirius would be here soon now that the wards have fallen. There was no time to waste. Hagrid had already been contacted so all he had to do was head to Surrey, where Minerva was already waiting. Oh, how he loved it when everything was going according to plan.

Back in the crib, the little baby girl cried loudly. The unfamiliar place scared her and she wanted to be with her parents.

-November 1, 1981-

Petunia Dursley nee Evans woke up with a feeling of dread that she usually associated with her Freak of a sister. Petunia had always hated her sister; even before her family found out about the magic. Why? Because, Lily was always the favorite. She was the smarter one; the prettier one; the perfect one. Lily always had to outdo her. When Petunia got married to the manager of Grunnings, Lily had to marry some kind of Lord. Their parents had always liked Lily more. And when Lily got her Hogwarts letter, that was just another reason to hate her.

So with trepidation, Petunia did her morning routine, wondering the whole time what her Freak of a sister did to maker her life miserable.

The answer to her thoughts came when she opened the front door half an hour later to pick up the morning milk. There, on her doorstep, was a small basket. Upon seeing what was inside, Petunia grabbed the basket and rushed back into the house.

Now, November in Surrey was cold. Petunia's first thoughts were to curse the monster that would leave a defenseless baby out at night with nothing but a blanket to keep warm. Her maternal instincts kicked in and within minutes, the baby was fed and warm.

Then, her mind turned to more pressing matters. What was she going to do with this child? She already had a baby of her own, but it was a boy. She had always wanted a daughter to take care of. As she was trying to decide how to convince her husband to keep the child, she noticed an envelope inside the basket. The second she finished reading the letter, all thoughts of keeping the baby were gone. After all, the girl was the child of her Freak sister which meant that the child was also a Freak! How could she raise such a thing in the same house as her Diddykins!

At this time, the man of the house, Vernon Dursley, came into the room. Upon seeing his wife's distressed state, he quickly asked what was wrong.

"Pet, what's got you all troubled?"

"Oh Vernon! I just found out that my sister is dead!" Petunia said in a distressed voice.

With a raised eyebrow. Vernon responded "I thought you hated her? The whole lot of them were Freaks right?"

"I do hate her! But that's not what I'm sad about. Look at what I found this morning! The Freaks left her child on out doorstep! They expect us to raise this thing!"

"What! I will not have it! No Freak will live in my house! What if it harms our Dudders? Get rid of her!" Vernon bellowed.

"We can't! They'll know if the brat isn't here! Here read the letter!" Petunia said as she handed the letter to her husband,

Dear Petunia,

I regretfully inform you that your sister, Lily, and her husband have passed away. A evil man by the name of Voldemort killed them and tried to kill your niece. Through some reason that I do not know, Catherine managed to survive. As Lily's only remaining family member, I leave young Catherine in your care. I know in the past that you and your sister have had differences, but I hope that you will put them aside and provide your niece with a good home.

I cannot stress the importance of Catherine staying at you house. It is my belief that powerful blood magic was done by your sister to keep Catherine alive. As a blood relative, some protection has no doubt transferred to you. In keeping Catherine in your house, you will also be protecting your family. I will have someone watching to make sure that Catherine remains at your home.

Also, Catherine will be seen as a hero in our world. It will not do for her to be too spoiled. A good sum of money will be transferred into your accounts every month for you to use to take care of Catherine. I would like to offer my condolences for your lost.

Sincerely Yours,

Albus Percival Wulfric Brian Dumbledore

(Order of Merlin, First Class, Grand Sorcerer, Chief Warlock,

Supreme Mugwump of the International Confederation of Wizards)

Vernon's face turned a myriad of colors to show his discontentment. "What gives those Freaks the bloody right to tell us what to do! I will not have this Petunita! No Freak is living in a house of mine!"

"But Vernon, you read the letter. Having the brat here will keep us safe. The mad Freak who killed my sister won't attack us with her here." Petunia reasoned.

"Why would we be attacked in the first place? We aren't Freaks like they are. Their bloody world shouldn't have anything to do with us!"

"I don't know. But if we don't, the old man might do some Freaky things to us. You don't want that right? Think of poor Dudley!"

"Fine! But the brat has to pull her weight when she's old enough. I won't have her dirtying the whole house so keep her in that room under the stairs." Vernon grumbled.

With that, the young girl was thrown into the cupboard and left alone. The following years would be hell on earth for the child and the ones to blame would be James and Lily Potter.

All around the Wizarding World, people were openng their newspapers and jumping for joy. The Dark Lord was gone! Killed by a child! Everyone cheered for the Girl-Who-Lived. Everyone cheered for Catherine Elizabeth Potter. And, while everyone cheered for the girl, no one thought to question her well being. They were too caught up in the moment to wonder where the Girl-Who-Lived disappeared to with no known living relatives with magic. And the people who did ask were answered by Albus DUmbledore, the Leader of the Light and Defeater of Grindewald. Surely someone as renown as he would make sure that the Hero of Wizarding Britain had a good home.
