DarkPriestess66 says I don't anything besides Snowdrop and Alexis and owl that doesn't have a name yet.

A young girl was sitting in a compartment on a train, it was the first time she had been away from her home in San Fransisco, California. She was curled up on the seat with her legs pulled up and thin blanket with a symbol of the triquetra covering her. Her active powers were pyrokinesis and creating energy blasts and a defensive power; she is able to create a shield around herself. Her shielding was purely instinctive; Also she had the ability to changed into a white Siberian tiger cub, none of the Warren line could have this power, she didn't know why she did.

"meow," purred a Silver shaded white Siberian cat, the girl hugged her feline friend closer,

"I didn't want to leave Prue, Piper and Phoebe, but they said it would be best for me; if I went school with children my own age," complained the girl.

The Cat rubbed against the girl, giving comfort.

She looks up as the door slides open,

"Sorry, I thought no one was in here," excused a boy around her age with a mop of black hair and green eyes behind glasses.

"Its fine, you can sit here, I would like the company, it's just me and Snowdrop here," the girl replied. Gesturing down to the cat.

"I'm Harry Potter," Harry introduced himself.

"I'm Alexis Halliwell, but call me Lexi," Lexi responded, she didn't know why but she felt she knew this boy, but it was impossible.

"This is you're first time to Hogwarts too?" asks Harry, as he took a seat on the other end of Lexi, she sat up and folded the blanket.

"Yes, my sisters said I should be around people my own age," Lexi replied. "or at least kids my own age that use magic."

"Are your sisters Muggles?" questioned Harry,

"Nope, all four of us are witches, My sisters come from a long line of witches, dating all the way from before the Salem witchcraft trials. Not me because I'm adopted," explained Lexi with a smile on her face. "But I still have powers because I was blood bound to them, so warren blood does run in my veins,"

Two heads turned at the sound of someone knocking, on the door.

"Can I sit here, everywhere else is full?" asks a boy with bright red hair.

"Sure, no problem." replies Lexi, Harry nodded.

"I was just telling him what its like in America," Lexi explains,

"Bloody Hell, you're from America, why are you doing out here in England." the boy with red hair ask.

"Sisters," was all Lexi said. "Oh, I'm Alexis but my friends call me Lexi, if I had any besides Harry that is."

"Ron Weasley," Ron replies.

Ron's eyes widen at Harry "Is it true that you have a...scar?"

Lexi looks at Ron like he lost his mind,

"Oh that," replies Harry, as he moved back some of his bangs to show a lighting bolt shaped scar.

Snowdrop arched his back and hissed,

"Snow, what is the matter with you." Lexi stated as she picked up her cat from the floor. "Sorry, my familiar has never acted like this before,"

"What's a familiar?" asks Harry,

"A familiar is a like guide for young witches in Wicca magic that is." Lexi explained, "Snowdrop has been with me since I regained my powers a year and a half ago."

"You lost your powers?" asks Ron, "How is that possible."

"My grams bound my powers along with my sisters, she thought it was a good idea at the time, but she passed away." Lexi answered softly. "and then when my older sister Phoebe moved back into the manor, she found our book of shadows and read an incantation from it and awaken our powers, next thing I knew I was getting a letter from a owl."

the boys laughed,

"Anything from the trolley, dears" an old woman states

"No thanks, I'm not allowed to have sweets." Lexi replies.

"I'm on set," Ron replies holding a bag of what used to a sandwich. Lexi wrinkled her nose at it, whatever it was now looked gross.

"We're take the lot," stated Harry,

an hour later, Lexi was staring at her two new friends with her mouth open. They eaten everything; wrappers were all over the seat opposite her.

"I cannot believe you two ate all that!" Lexi exclaimed, she blinked and shook her head.

"This is Scabbers, by the wall, my brother Percy gave him to me." Ron stated as a rat was in a popcorn container. "Fred gave me a spell that can turn him yellow want to see?"

"Sure, you bet." Harry stated.

Just then a bushy haired girl appears in the doorway,

"Have any of you seen a toad a boy named Neville lost one?" the girl asks, "I'm Hermione Granger,"

Lexi shook her head, and curled back on the seat. She was already in her uniform.

"You are preforming magic lets see then," the girl stated.

Ron tried his spell but it backfired on him and Lexi giggled. Hermione fixed Harry's glasses.

"I'm surprised that you haven't asked me to preform magic," Lexi stated.

"Oh and what can you do?" Hermione asked.

Lexi smirked and held out her hand and a fireball appeared, making the three gasp. Lexi closed her hand and the fireball disappeared.

"I also can create energy blasts, and I have a shield." Lexi stated then looked at Hermione. "I'm Alexis Halliwell."

Hermione's eyes widened even more then they did when she recognized Harry Potter. "Aren't the Halliwells the Charmed Ones, the most powerful witches of all magical world.

Lexi looked down "Stop you're making me blush,"

"You're a Charmed One!" explained both Ron and Hermione.

"Pretty much, The Power of Three is good but add my magic and you get the ultimate power, the Power of Four." Lexi stated. "This is the reason, I had my powers bound." Lexi answered "Don't see the point, it's not like I can be a force to be reckon with by myself."

The train stopped and everyone got off, and went to the Castle. The first years by boat.

Lexi waited with Harry and Ron, she had to admit she felt like they were her friends. She listened as the Professor explained the house and rules and then waited to be called in.

"So it's true then. What they're saying on the train. Harry Potter and Charmed One has come to Hogwarts." sneered a pale blonde
Lexi snorted ever since she told her friends she was a Charmed One, she was hounded by questions.
"This is Crabbe, and Goyle. And I'm Malfoy. Draco Malfoy."
Ron snickers while Lexi glared at this fool. She didn't know why but he kinda looked like her, could they be related somehow, if they were cousins or something she would have to kill herself.
"You think my name's funny do you? No need to ask for yours. Red hair, and a hand-me-down robe. You must be a Weasley. You'll soon find out some wizarding families are better than others, Potter, Halliwell, You don't want to go making friends with the wrong sort. I can help you there." Malfoyoffers his hand.

"I think I can tell the wrong sort for myself, thanks." Harryanswered Lexi glared at the hand, "No thanks, my sisters would not like it if I were friends with someone like you. Besides I vanquish evil beings everyday, avoiding you will easy compare to stuff I faced."

Lexi waited with Ron and Harry beside her. 'what if I don't get sorted into the same house as my friends?'

"Alexis Halliwell." called Professor McGonagall after Harry was sorted into Gryffindor House. Lexi walked up to the stool and sat on it; breathing to calm herself down. She felt the hat being placed on her head. "This is strange, I sense two forms of magic running in your veins, Ah...I understand now...you are a blood-adopted Halliwell, cunning, loyal to anyone who wins your trust..., brave, smart...but where to put you." "Anyway, I don't care." Lexi told the hat. "I can't decide." the hat shouted. A Silent gasp filled the room. "Does this mean, I have to go home?" Lexi asks, she was hoping to stay, she was starting to like Hogwarts. "No, we have special dormitories for people, in your situation" Dumbledore replies. "Does this mean, I don't have to wear the uniform?"
