Prologue~

"James Harrison Potter, I am so going to kill you!" shrieked the disgruntled Lily griping her wand.

James gulped nervously holding his wife's hand."

"Come on, Lils. I know you can do it…" Lily nodded and looked at James. He kissed her then Lily turned her attention on the Med-witches and after receiving a nod, started pushing.

"I'm never having another baby again," Lily screamed as the sound of cries filled the room.

"Congratulations, Mr. and Mrs. Potter. You have given birth to a healthy baby girl!"

"Girl? But that's not…AHHHH," Lily started then began screaming again.

"Another Baby is coming. Push, Mrs. Potter," the Med-witch said in shock.

Lily's eyes widen and nodded pushing again with everything she had.

"Congratulations, Mr. and Mrs. Potter, you have given birth to a beautiful set of twins."

"Look what we brought in this world," James smiled through his tears and nodded holding the auburn haired baby girl.

"He looks just like you. And they both have your hair, even now when they're just a babies it's sticks up at all the places," Lily smiled taking the baby boy into her arms.

"What can I do? Blame it on the Potter genes…Gods, she looks just like you. Wait; we don't have a name for her."

"Yes we do, I kind of had a name picked out since we got married."

"Well what is it?"

"It's Rowena, like Rowena Ravenclaw. Her name is Rowena Lilac Potter."

"That's a beautiful name."

The doors banged open and two of his best friends, Sirius and Remus, stormed in the St Mungo's room. James turned his back to them, hinding Rowena from them.

"Padfoot, get over here and meet your godson," James said to the two men standing at the door. Sirius walked over and looked at the baby boy.

"So what's my little Prongslet's name?" Sirius asked.

"Harrison James Potter, or Harry for short," Lily smiled.

"Harry Potter; I like it," Remus smile.

"Remus, would you like to meet your goddaughter?" James smiled, turning to show them the little girl in his arms.

"You had twins? Why didn't you tell us? She's perfect! What is her name," Remus asked, staring at the baby.

"Rowena, Rowena Lilac Potter," Lily smiled.

"If she looks anything like you Lily you'll have a tough time fending off potential boyfriends in a few years." Sirius smirked.

"Boyfriends? God she's 10 minutes old and you already got me trying to kill someone," James paled at the thought and Lily just laughed tiredly.

"Don't worry, no boys will get pass the three of us," Remus smiled taking the baby girl.

"Damn straight, she'll our little Marauder princess," Sirius smiled.

"Oh gods," Lily giggled

"You'll always be the Marauder Queen Lil," James smiled kisses her.

Two weeks earlier, the Headmaster of Hogwarts School of Witchcraft and Wizardry was in his office in the middle of interview with Sybil Trelawney who was sitting in the chair opposite the desk. Suddenly Trelawney went rigid and her eyes fogged over, completely white. Her voice went down several octaves as she began to speak in an eerie voice.

The only ones with the power to aid the Dark Lord approaches...

Born to those who have thrice defied him, Born an Equal and a moral compass, both born as the seventh month dies...

The Dark Lord will mark them as his equals,

The moral compass will have a power the Dark lord knows not, She will lead The Equal to him

The Dark Lord and his Equal will either rule together, or destroy each other.

For either to die, it must be at the hand of the other for neither can die while the other survives...

Dumbledore sit there, staring at Trelawney with a stunned, dumbfounded look, rarely seen gracing his features. Trelawney came out of her trance looking rather confused.

August 1st the head master looked at the list of students that would join in 11 years. He stopped as he saw that there were three new names that were added in the last days of July Neville Longbottom, Rowena Potter, and Harry Potter. The Potter Twins had to be to ones of the true. Dumbledore had planted a false one and Voldemort had already chosen the Potter child as his victim. If the Dark Lord killed the twin then he'll have the other one in his grasp.

Grabbing a little Floo powder the old man threw the powder in the fire and after it turned green stepped in and yelled his destination in a clear voice, "Potter Residence!"

He got swept away and gracefully stepped out of the home of Lily and James Potter. He looked around and noticed that no one seemed to be in the room. He went out to the living room.

James was sitting on a couch a messy haired baby boy reading him a Quidditch magazine while Lily held a small redheaded girl whose small arms were wrapped around a small plush wolf.

"Albus what are you doing here," James said, looking up at the Headmaster.

Sighing sadly he said, "I came here today because I suspect that Harry is one of the two babies that a prophecy that was made earlier this year is speaking off."

"What prophecy?" Lily said dangerously, putting Ro in her crib.

Dumbledore sighed and place powerful Silencing, and Secrecy charms on the room, so that they wouldn't' be overheard,

"The one with the power to vanquish the Dark Lord approaches ... Born to those who have thrice defied him, born as the seventh month dies ... And the Dark Lord will mark him as his equal, but he will have power the Dark Lord knows not ... And either must die at the hand of the other for neither can live while the other survives ... The one with the power to vanquish the Dark Lord will be born as the seventh month dies..."

"And you think its talking about our Harry. Well, we'll have to leave, go to America; I don't think Voldemort has reached that far," James said in a panic.

"No, I believe it is safe to stay in one place under the Fidelius Charm. I'll cast it myself, and of course you'll have chose two secret keepers, one the real one and the other would be the false trail."

"Remus and Sirius," Both Lily and James said.

"Of course, But do you think it wise? Remus is a werewolf and our spy and it is very dangerous to trust him as they can easily kill him."

"Okay, I guess we could use Peter," James suggested.

"Yes, no one would guess you'd choose him."

"They are the worst kind of Muggles you can ever meet, Albus!" said Professor McGonagall.

"It's the best place for them," said Dumbledore firmly. "Their aunt and uncle will be able to explain everything to them when they are older. I've written them a letter."

"A letter? How can a letter possible help," repeated Professor McGonagall faintly, sitting back down on the wall.

"Now, now, Minerva, Harry will be safe with them and they are his only living relatives."

"And what about Rowena? That pig of a man in there, I wouldn't put it pass him," Minnie yelled.

"Now Minnie, I assure you the Potter Twins will be safe."

"Shouldn't you've waited until the will is read? Lily would never want her son with such people, Albus."

"My dear Minerva, you and I both know Lily and James could not get around to making a will. And if they did, they would have named Sirius or Remus as the guardian," Albus spoke as he laid Harry and Rowena gently on the doorstep, took a letter out of his cloak, tucked it inside Harry's blankets, and then came back to the other two. Professor McGonagall blinked furiously, and the twinkling light that usually shone from Dumbledore's eyes seemed to have been put on high. "Well," said Dumbledore finally, "that's that. We've no business staying here. We may as well go and join the celebrations."

Dumbledore turned and walked back down the street. On the corner he stopped and took out the silver Put-Outer. He clicked it once, and twelve balls of light sped back to their street lamps so that Privet Drive glowed suddenly orange and he could make out a tabby cat slinking around the corner at the other end of the street. He could just see the bundle of blankets on the step of number four.

"Good luck, Harry and Rowena Potter," he murmured. He turned on his heel and, with a swish of his cloak, he was gone.
