Hey every one Thought about doing a crossover between Percy Jackson and Harry Potter. The main OFC is going to be from Percy but ends up in Harry's world. I DON'T OWN ANYTHING BUT THE OFC AND PLOT! ! ! P.s. This has nothing to do with the books and things will change. Some people who lived might die and the same with the people who die might live. And what ever is in Greek I put in English at the very end of it. And in the Nectar and Ambrosia can do more then just feel demigods. I know in the Percy Jackson its only used for food or healing. But that back home but in Harry's world its more then that. I'm not going to say what it does. You just have to read and see. Hope you like it.

Chapter 1: Your Crossroad Has Came

Alice's POV

I was in Britain helping the demigods get to the safe zone. So that they can get to Camp Half-Blood/Camp Jupiter.

My mother make a portal from both camps to make one. If you step threw it you be transfer to the other camp in seconds.

There are portals all over the world in safe zones to get other demigods to the camp safely. Since the war was over there wasn't a lot of demigods left. So the Gods make safe zones to bring them to the camps.

But as I left the demigod I ran into my mother Hecate The Goddess of Magic & Witchcraft, The Goddess of Crossroads and The Goddess of the Mist.

There was some fear her eyes.

"What wrong mother?"

I said and she grabbed me and we vanished.

"Your in danger my child and now you at a crossroad. You have two paths to choose from. You can stay here and die or go to a different dimension."

She said and I didn't know what to do.

"What did I do wrong?"

Came out of my month. A sad smile fell on her face.

"Nothing you did it was me. You must choose now."

She said with more urgent in her voice. My mind raced.

"I thought you didn't have the power to open a portal to a different dimension?"

I said. Mother told me that there was a lot of different dimensions. But she didn't have the power to open it.

"I don't have the power but you do. I can show you how to open it." She said. I bit my lower lip.

"I take the different dimension."

I said in a low voice. She kissed my forehead and handed me a black backpack.

"Every thing you need is in the bag."

Then she touched my forehead showing me how to open the portal. As I opened it I turned to look at her.

"How will I know if I picked the right one?"

I ask and she knew what I was talking about.

"You will pass a few dimensions which ever one that feels right go for that one."

Hecate said to me. Before I could say anything she pushed me threw the portal.

I fell threw darkness then light. I closed my eyes and left my body fell for the magic that was in my blood.

Nothing but then I felt a strong power that felt like magic. But it was different from mine.

I turned my body that way and headed for that dimension. As I came out of the portal I fell out of the sky.

Was this her plan to kill me ether way?

I thought as I fell to earth. Then I felt the wind blow around me and I closed my eyes as the ground came closer to me.

But I didn't hit it. I slowly opened my eyes and saw that I stopped a foot from the ground.

The wind slowly put me down. I had my bag with me as I started to walk.

I could fell evil magic and good magic fighting close by. I changed my shape into a red wolf.

I had my bag in my month as I ran. While I'm in my wolf form my scents of direction was a lot better.

I know my mother's animal is the dog but the wolf was the first dog so I took its shape. As I ran I came to the spot.

I put my bag behind a bush and moved closer. There was a old man in the middle of a group of people.

They had wands pointed at him and he had his at them. I couldn't tell what they were saying, I was to far away.

As I watch the old man was bleeding.

Another crossroad.

I thought to my self. Being the daughter of the Goddess of Crossroad. That's how I see the world as. Crossroads is everywhere if you think about it.

I could leave the old man to die. Or I could go and try to save him.

Or I could sit here and watch them kill him then I could go and kill them for killing the old man. But I wasn't like that, I moved slowly around them as I moved I grew bigger.

Then before anyone could move I ran and jumped on the man that was in front of the old man. I sang my fangs into his neck.

As he fell I snapped his neck. As I let go I let my power leave my body sending the bad men a few feet away.

Then I turned my back to the old man and turned back into a human. As I did that I pulled out my sword and shield.

"Stay here will I get them."

I told the old man. Before he could speak and I ran and ducked under the first one and cut him in half.

I felt magic coming towards me. I put my shield up and the spell bounced off and hit the person that sent it.

He or she fell dead. The others vanished.

I couldn't fell their magic so I ran back to the old man. He leaned up against the lamppost.

"Are you ok sir?"

I said as I make my sword and shield vanish.

"Yes but I need to get back to the other to tell them."

He didn't go on but he couldn't stand. I bend down to look at his leg. It was bad and wouldn't be walking for a while.

"Let me heal your leg."

I said as I muttered under my breath and touched his leg. When I got back up on my feet.

The old man was looked at me with sparkling blue eyes.

"How did you do that?"

He said to me.

"Magic."

I said with a small smile.

"I see that. Were did you come from?"

He asked but I looked away just remembering what happened.

"You need to get going before they come back with more."

I said in a sad voice.

"Why did you help me?"

He said and I looked at him.

"Cause your magic is good theirs were evil."

I said and he smiled more.

"I would like to talk to you more would you like to came back with me? I might need help walking."

He said and I nodded. I didn't have any place to go.

"Ok just take my elbow and we get off."

He said. Before I did that I made my bag flew at me and once I had that.

I took the old mans elbow and he turned on the spot. As he did this it felt like I was being sucked into a small tube.

Then every think was normal. I let go and fell to my knees taking in deep breaths.

"Are you ok?"

He said as he put his hand on my shoulder to steady him self.

"Yes I never done anything like this before."

I said as I got up and put my bag on my back and helped the old man. Down a path in the woods.

Nether of us talked then a house come out of the woods.

No One's POV

The Marauders and Lily were sitting in the kitchen waiting for Dumbledore to come back.

"Were is he? He should have been back by now. You don't think anything bad happened to him?"

James said as he held his wife Lily's hand.

"Don't worry love he be back soon."

She said. Then Sirius yelled cause he was looking out the window. "He's back!"

He said as they ran out the back door to their head master. When they got their none of them saw the girl that was holding him up.

As they took him in to the house and sat him down. They started to ask him wait happened.

Then Dumbledore started to tell him.

Alice was left standing out side not sure if she should follow them. But they didn't seem to see her.

So she walked out of the woods and laid in the cold grass. The stars were shining bright.

Alice didn't have time to just lay down and look up at the stars. She pulled her bag closer and opened it.

There was a letter on pined on the inside of the flap. Alice took it off and started to read it.

My dear Alice,

By the time you read this you will be safe. I couldn't tell you in person but you cant never return to our dimension. If I told you when I saw you. You wont have left and I would have watched you be killed. I hoped I had more time with you.

I know I didn't have time for you and our brothers or sisters. But you are more powerful then them. That's why I kept you far away form the other gods. You are just like me.

I gave you all the powers that I have. I knew you didn't understand some of the power that you willed. You know my history, use it to help you live. I made sure that you cant open the portal to any other dimensions. After you fond the one you wanted that's the only one you will live at. Make that on your home and keep it safe. I gave you a gifted before you left.

I'm not going to tell you but when the time is right you will feel the gift. When that happens another letter will come. I want you to know that I'm proud of you. Sorry that I made you to powerful.

I knew the crossroads when I did that. But I just hoped that it would have turned our better.

LOVE,

HECATE

Tears were running down Alice's face. Alice jumped to her feet and started to scream.

Dumbledore finished telling the other what happened. When they heard someone screaming out side.

They ran out with there wands out. Once out side they could hear what the girl was saying.

"MOTHER WHY DIDN'T YOU TELL ME! MOTHER I DON'T WANT TO BE HERE ALONE! ! HOW COULD YOU DO THIS TO ME?" They didn't know what to do. Dumbledore stood next to Sirius. "MOTHER, MOTHER WHY! ? !"

They knew she was crying. She fell to her knees then she raised her fists and hit the ground hard.

They didn't expect the ground to shake.

"What or who is she?"

James side and he moved in front of Lily.

"Should we bind her?"

Sirius said. At this the girl flew to her feet and faced us and fire formed in her hands and went up her arms.

But then she looked at Lily and the fire went out and she sat back down. Her back towards us and she cried into her knees.

"She's not from here."

Dumbledore said softly as he moved closer to the girl. The other followed him.

"Would you like to come in and warm up?"

He said and the girl looked at him. Her green eyes were red and she nodded.

But he thought her hair was blonde not black? She struggled to her feet and she picked up her bag.

She took a step and her legs gave out. Sirius caught her and they looked at each other for a while.

Then he smiled at her.

"Let me help you."

He said as he moved his arm around her waist and put her arm around his neck. As they walked Lily was smiling a little at the way Sirius was smiling at the girl.

Back in the kitchen Sirius put the girl in a chair. She looked like she been threw a lot.

"Would you like some tea?"

Lily asked softly to her. She looked up at her.

"Do you have anything strong to put in to it?"

Alice said.

"How old are you?"

Lily asked.

"19 going on 20."

She said in a weak voice. Lily nodded and make her a cup of hot tea and put some fire whiskey in it.

Then she gave it to the girl. Alice down it and moved the cup away. "What's your name?"

James asked Alice. She moved her green eyes at him.

"My name is Alice."

Alice said in a dead voice.

"Why were you scream for?"

Remus asked her. She moved her eyes towards him.

"You wouldn't understand even if I told you."

Alice said as she put her arms on the table then put her head on them. "Try us."

Sirius said. Alice's hair turned blonde.

But with all the dirt that was in it you couldn't tell.

"Fine. I'm form a different dimension which is very different form this one. Back home the Greek and Roman gods are real. They have kids with mortals also know as demigods. My mother is Hecate the goddess of Magic & Witchcraft, The Goddess of Crossroads and The Goddess of the Mist. But she also has more powers then that. Zeus, Poseidon and Hades gave her control of the sky, ocean/water, and the dead."

Alice said and they were just looked at her like she was crazy.

1*"Το ήξερα ότι δεν θα με πιστέψετε."

Alice is in Greek. None of them beside Dumbledore understood her. "What the bloody hell did you just say?"

Sirius and James said at the same time. But it was Dumbledore who spoke.

"That was Greek and not a lot of people around here knows how to speak it so good."

He said.

2*"Αχ ξέρετε Ελληνική τότε να τους πούμε. Είναι τραντάγματα και αν με τσαντίσεις θα τους ψητό."

Alice said to him. Dumbledore didn't know if she meant it or was just playing around.

"What did she said?"

James said.

"I don't think you want to know."

Dumbledore said. Alice looked at him.

"If you piss me off I will roast you."

She said and no one talked. Then she rolled her eyes.

"I was just kidding. I will cut you in half."

She said as she pulled her bloody sword out of nowhere. Every one watched her pull out a black cloth and started to clean the blade.

"Really?"

Lily said in a weak voice. Alice looked at her.

"No I don't kill the innocent or the good."

Alice said as she pulled out this stuff and started to put it on her huge sword. That is after the blood was gone.

"Why?"

Sirius said. Every one looked at him

"Cause they don't need to die. I seen a lot of young demigod killed by monsters. Most of them are ripped apart painful. Other die much worst. Greek demigods don't make it to see their adult years. That's why I found them and sent them to the camps."

Alice said.

"Life is nothing but Crossroads."

She said as she started to work on her sword again. No one really understood why she said that.

Then her eyes turned black and she started to speak in Greek again. But this time her voice was different it was softer and darker.

3*"Είναι κοντά θα πρέπει να αποφασίσει σταυροδρόμι του. Θα πρέπει να επιλέξουν μεταξύ εξουσίας και τους φίλους του!"

Alice closed her eyes and she looked at them. Dumbledore stared at her.

"I thought you said your mother is Hecate?"

He said and Alice looked at him.

"She is but she is also the cousin of Apollo The God of the Sun, Light, Poetry, Healing, Truth, Plague, Prophecy, Music, Arts, the Oracle, and more. So Healing, music and oracle is some of my powers. But the oracle prophecy's only comes to me when I can change it so save life's. I'm not a Oracle only the prophecy's of some came to me."

Alice said as she put up her sword. But before any one could say anything the front door banged open and people were yelling for help.

The others ran and Alice slowly got up and followed them. When her eyes fell a pawn the little ugly man.

Rage built up inside her and she didn't know why.

1* I knew you wouldn't believe me.

2* Oh you know Greek then tell them. They are jerks and if they piss me off I will roast them.

3* He is near he must decide his crossroad. He will have to choose between power or his friends!
