This story will be a Harry Potter/Merlin crossover.

Morgana Pendragon is reincarnated as Morgan Potter, and though she's still Voldemort's horcrux and she's known to the Wizarding World as the girl-who-lived, Neville Longbottom is the actual child of the prophecy, the one destined to kill Voldemort or die. Dumbledore is the only one who knows this because he's the only one who heard the prophecy in its entirety, a prophecy that definitely refers to a boy. Voldemort attacked the Potters not knowing that the prophecy was referring to a boy and not to a girl, because he only heard the first three lines. I'll explain how it is possible for Neville to be the one 'marked' as Voldemort's equal during the story later on.

This will be a Morgana - who is also FemHarry -/Voldemort fiction. Though Voldemort will look like an older version of Tom Riddle, not Voldemort-snake-face. And he will be saner than in Canon, though still very much evil.

Dark!Morgana/FemHarry, Evil!Morgana/FemHarry - though a little saner than in Merlin season5.

I don't have much to say beside the fact that it will follow the general storyline of the Harry Potter books, though there will be differences since FemHarry will be evil in this story and not a Gryffindor and Neville is also the boy-who-lived.

My Character - called Morgan Potter - will be a mix of Morgana Pendragon in Merlin and a Dark!Evil!FemHarry (prodigy, powerful, smart and with sociopathic tendencies like Tom Riddle). And yes, she will look like Morgana in Merlin - Katie McGrath - because she is Morgana.

I've still put this story as a crossover because technically she is Morgana, though not only Morgana. She's the reincarnation of Morgana.

Merlin will appear too, though only during the events of 'the Deathly Hallows' and the Horcruxes' hunt, not before.

I hope you like it.

Prologue

THE LAST HIGH PRIESTESS

"What if magic isn't something you choose? What if it chooses you?"

"Every day I must look Uther in the eye knowing that if he were to discover who I really am, he'd have me killed."

"I know what you did. You tried to poison me!"

"I have magic, Merlin. Uther hates me and everyone like me. Why should I feel any differently about him?"

"You don't know what it's like to be an outsider. To be ashamed of how you were born, to have to hide who you are. Do you think I deserve to be executed because of who I am?"

"We can find another way"

"There is no other way"

"I can see deep into your heart. And it's cold, cold as stone. You play Uther's loving ward, you play it so well. You fool him but you don't fool me. You would see Uther dead. And Camelot destroyed. There is evil in your heart"

"YOU HAVE NO RIGHT TO THE THRONE!"

"No, she does not, but I do. I'm your daughter after all"

"First I want you to suffer as I suffered. To know what it is like to be alone and afraid, to be disgusted with who and what you are... "

"These people are innocent!"

"As were so many that you put to death."

"What have you become?"

"It's what you taught me father"

"I blame Morgause and her magic for corrupting you"

"Once again how wrong you are. Morgause saved me, made me feel I wasn't a monster. I didn't choose my gifts, like I didn't choose my father. Yes, magic made me who I am, but so did you Uther Pendragon"

"I want you to live long enough to see Arthur die by my hand"

"Do you really hate me so much?"

"You cannot begin to know how much I hate you"

"It's over Morgana"

"No, you're wrong. This has just begun"

"The one they call Emrys will walk in your shadow. He is your destiny, and he is your doom"

"Don't think I don't understand loyalty just because I've got no one left to be loyal to"

"Please spare me, I only want what is rightfully mine."

"You're consumed by bitterness Morgana. It spread within you like a disease"

"Go ahead, make peace with Arthur, but I will not rest until all of Camelot bows before me"

"What happened to you Morgana? I thought we were friends"

"As did I. But alas, we were both wrong"

"I am going to enjoy killing you Arthur Pendragon"

"What did I do to make you hate me so much?"

"It's not what you did, it's what you are destined to do. I'm sorry, Gwen but I can never let that happen."

"KILL HIM! That's all you had to do! I am a High Priestess! I have the power of the heavens in my hand and yet he continues to defy me!"

"I want his annihilation, Mordred. I want to put his head on a spike and watch as the crows feast on his eyes."

"I'm sorry for what our father did to you"

"Uther was never my father"

"But we are brother and sister"

"Funny how you choose to remember that with my dagger at your back"

"What happened to you, Morgana? As a child, you were so kind, so compassionate..."

"I grew up. You are right to cower before my hand. I am more powerful than you can ever imagine"

"And yet with all that, you choose to do nothing but hate"

"Uther taught me well"

"Such hatred as yours can never triumph. I hope one day you will find the love and compassion which used to fill your heart"

"There is someone you have been searching for. Someone who has always eluded you."

"Emrys."

"I know where he is. Camelot. And I have his true name. It is Merlin"

"Why do you hide? You still afraid of me?"

"I fear no one. Least of all you."

"You have defied me for the last time, Emrys"

"I WANT HIM DEAD!"

"EMRYYYYSSSSSS"

"The battle's not over , Mordred. We will have our revenge"

"What a joy it is to see you, Arthur. Look at you. You're not so tall and mighty now. You may have won the battle but you've lost the war. You're going to die by Mordred's hand. Oh, don't worry, dear brother. I won't let you die alone. I'll stay and watch over you... until the wolves gorge on your carcass and bathe in your blood."

"No, the time for all this bloodshed is over. I blame myself for what you've become, but this has to end."

"I am a High Priestess, no mortal blade can kill me"

"This is no mortal blade. Like yours, it was forged in a dragon's breath. Goodbye, Morgana"

She woke up with a gasp, the images of her nightmares forever burned behind her eyelids, the phantom pain of a sword piercing through her back staying with her even once awake. It was not the first time she had had those strange dreams, but it was the first time the images had been so vivid. They were more than dreams, they were memories, she was sure of it.

She was her. In these dreams, she was always her. The incredibly powerful, beautiful and evil witch that had been able to raise an army against Camelot and Arthur Pendragon. Morgana.

But it was impossible. How could she be the mythical figure of the stories? They were just stories, nothing more. None of those people had really lived, magic didn't exist. How could she be her, the most powerful magical being that had ever lived besides Merlin himself, if those stories were to be believed?

She shook her head but no matter what her brain was telling her, a part of her couldn't dismiss entirely the hope inside her that she was something more than what her relatives and all the people in her life considered her to be. She wanted to be more. She wanted to prove to everyone who had ever dared tell that she was nothing, that she was better than them, better than everyone else.

And what about those strange 'accidents' that had happened since she was four years old? Things that had suddenly exploded around her, or had caught fire or had started shaking when she had been angry, scared or upset? Or all the times she had been able to throw Vernon or Dudley across the room the few times they had dared tried touching her, wanting to hit her, to show her 'her place'.

It seemed they never learned. Their fear lasted for a little while but then, they seemed to forget what she was capable of and tried to hurt her again. But every time, that something inside her reacted to the danger and fought back. They had never been able to hurt her since she was six years old, the first time she had been able to throw one of them across the room and against a wall.

Was it possible that what she could do was magic? It didn't seem as unbelievable as believing that she was the...what...'reincarnation' of the legendary 'Morgana LeFay'? And yet, both of those things seemed to be true.

How could she explain those strange dreams otherwise? And what about her other dreams? The dreams about things that had not happened yet? Dreams about the future, exactly as Morgana was able to do.

She looked around, at the bedroom that had become her room since the first time she had been able to defend herself against Vernon. She looked at her reflection and noticed the similarities between herself and the woman in her dreams. She was younger of course, she was only eight years old, but they had the same pale skin, the same dark wavy hair and the same emerald green eyes. The only difference was a strange, lightning bolt shaped scar on her forehead.

She wanted to be like her, the woman in her dreams. Morgana Pendragon. She was evil yes, but she was also beautiful and powerful and inspired fear, awe and respect in everyone who met her. Morgana would have never let anyone treat her like the Dursleys treated her. Morgana would have hurt them, possibly killed them, just for daring trying to treat her like she was nothing.

Morgan swore to herself that, from now on, nobody would ever treat her like the Dursleys had dared treat her. But first, she needed to learn magic and become powerful once again, powerful as she was in her dreams. Fortunately she had enough knowledge from her dreams about the spells she had used as Morgana - a High Priestess of the Old Region - that learning to control her powers would not be so difficult. At least, she hoped so.

She decided to try a simple spell, one used to conjure fire.

"Forbærne" She said in a whisper, concentrating on wanting the fire to appear. She noticed out of the corner of her eye, her eyes reflected in the mirror turning gold. A second later a tiny flame appeared on her palm. She smiled in satisfaction.

Soon, she would be as powerful as she was in her dreams and then nothing or no one would stand in her way, whatever thing she would decide to do in the future.
