I've been wanting to write this ever since I read all seven Harry Potter books for the first time this Christmas.

Prologue: Kai

Kai was the only person who sat in his train car for the past two years.

Everybody else in the train tended to avoid the moody, easily angered young wizard with the "weird" hair and who came to his first day at Hogwarts with an injury from trying to wrestle a werewolf one fine summer's day.

There were (justified) rumours that he was a werewolf now, but they were untrue. The injury was simply from his head being thrown into a window by the (untransformed) werewolf who didn't want to fight anyone, much less a ten year-old.

So, obviously, Kai was surprised when a strange kid (he might have seen him, but not in the Griffindor common room) popped into the car and started talking to him as if they were old friends.

"So my mom said that I can come to your house next holiday, as long as your dog doesn't try to eat my foot again," the boy said, as if Kai was supposed to know what he was talking about.

Kai didn't even have a dog.

"Who the hell are you?"

The boy laughed as if he just heard the funniest joke in the history of the world.

"Seriously, who are you?" Kai asked. "Nobody comes into my car. Ever."

The boy grinned at him. "Can I show you something cool?"

"Are you deaf?" Kai had a valid point. The boy didn't seem to hear what he was saying. "I asked you who you are."

The other boy ignored his question and pulled a little box out of his pocket.

"You have to promise not to tell anyone, okay?" the boy asked, staring at Kai with big, bright blue eyes. "She's harmless, I swear."

Giving up on trying to get the strange boy's name, and at the same time, curious about what the boy wanted to show him, Kai nodded. "Okay. I won't tell anyone."

The boy lifted the lid of the box, which allowed a long, thin, feathery blue serpent to come flying out and wrap itself around the boy's fingers, making odd, happy noises as it did so.

"What is that?!" Kai asked, jumping back in his seat as the creature, startled, grew in size and clumsily plopped down on the floor, leafing bright blue feathers everywhere.

"She's an Occamy." The boy shook his little box for the Occamy to enter, which it did after shrinking, then he put it back in his pocket. "Her name's Wisp, and she likes chicken."

"My name's Kai," Kai told the boy, "and I like being alone in my car."

The boy grinned again. "My name's Jay!"

Kai rolled his eyes. "What I mean is, GET OUT!"

Jay didn't seem to catch the hint. "My mom baked enough cookies to feed the entire Slytherin house for the whole term, but they're all mean, so I thought that maybe you'd like some?"

Kai growled about how wizards needed to respect each other's cars and leave them alone, but Jay didn't seem to catch that either. He was too busy pulling a box of cookies out of his bag and offering them to Kai before taking one and stuffing it into his own mouth.

The cookie was really good.

Jay's mom officially earned Kai's respect. She baked a mean cookie.

"These are really good," Kai told the other boy.

Jay turned slightly pink. "You're actually the first person to try one," he told Kai, "other than me."

There was some weird noise on the other side of the door, and before Kai could ask the boy for another cookie, he left. Leaving behind a paper bag filled with some of the delicious cookies.

Prologue: Zane

This was Zane's first year at Hogwarts after six years at Mahoutokoro, and he was nervous.

What if the other students don't like me? What if they find me strange, like the other students at Mahoutokoro? What if I get put in the wrong house? What if…

A first-year student bursting in through the door of his car in brand-new black robes snapped Zane out of his thoughts. "This isn't the right cart!" the boy shouted in exasperation, then he sighed. "Can you help me?"

Zane nodded and stood up. "Of course. What do you need help with?"

The boy turned pink. "I can't find the first-year's car."

"Are there any rules against you sitting in the car with a third-year?" Zane asked kindly.

The boy thought a little, then he shook his head. "I don't think so, no."

Zane sat down and patted the seat next to him. "I think my father packed a few too many Chocolate Frogs. You may have some."

The younger boy looked surprised. "Really?"

Zane nodded and gave the boy half of his Chocolate Frogs to prove his point.

Upon opening the first box, the little boy let out a scream and ducked when the frog jumped at his face.

"I didn't know they were alive!"

Zane shook his head. "They are not. There is a magical powder in them to make them jump like that."

The boy caught his frog and bit off the head. "Wow, it's really good! And look!" The boy tried to put the card that came with the frog in Zane's eye. "It's got a card!"

Zane chuckled as he carefully took the card out of his eye and looked at it.

The picture was of a creature with glowing red eyes, four arms and coal-black skin grinning wickedly back at him.

Everything went black, and all of a sudden, he had another vision, like those that caused the other students back at Mahoutokoro to think that he was weird.

He saw a pair of wizards duelling, fire and ice and electricity being shot from wizard to wizard, blocked and shot back over and over again.

The younger wizard seemed to be trying to protect something, which the older wizard was obviously trying to get to.

The older of the two, though not by much, was suddenly struck by lightning from above, and screamed in pain as the earth broke open and swallowed him.

The next thing Zane knew, he was all alone in an empty car.

His vision must have scared the young boy off.

He knew that he would sometimes speak when having a vision, but he never knew what unless someone told him.

The boy even left behind his Chocolate Frogs.

I hope he found a car with some nice, non-freak wizards and witches in it…

Prologue: Jay

After leaving Kai to mope by himself, Jay found a car with the fourth-year Hufflepuff, Cole Brookstone, hiding in it.

Jay decided to leave him be after he was given a dirty look that put Kai to shame, and went ahead, eating some of his mom's "friend cookies" as he walked.

None of the other Slytherin kids wanted to have one, but Nya, Kai's younger sister, was waiting for him to come back and tell her if her brother was okay, and when Jay got to her, she had already eaten most of the cookies he left behind with her and had a guilty look on her face when he caught her.

"I'm sorry, they're just so good!"

"It's okay." Jay plopped down next to the Ravenclaw girl. "Kai's being a butt, just like you said he would, but he also liked the…"

A first-year ran through the car, screaming in terror, causing Jay to forget what he was about to say next.

Nya seemed to forget that she was worried about her brother, though, so Jay didn't feel as bad as he should have.

"If that kid thinks that the Hogwarts Express is scary, he should not go to the Forbidden Forest," Jay told Nya. "Poor kid. Imagine what'll happen when he meets the Hogwarts ghosts?"

"So, are you trying out for Quidditch this year?" Nya asked, motioning to Jay's broomstick.

Jay snorted. "Yeah right."

Nya nodded. "Okay, then. So what's the broomstick for, then?"

"Professor Gordon owled it to me by mistake or something over the summer." Jay stuck the broom under the seat. "I'm going to give it back to him next time I catch him."

"And if it wasn't a mistake?" Nya asked. "It's a pretty nice broomstick, you should try it out sometime!"

"It was a mistake, Nya." Jay fixed the sleeve of his robe. "Remember last year, when he accidently sent that owl to me when he actually meant to send it to his nephew for his birthday?"

"It was a very cool owl," Nya told him. "His nephew's very lucky."

Jay nodded. Said owl was a majestic Eurasian Eagle Owl, and when it slammed into Jay's window the previous year, the first thought he had wasn't "Oh, my friends have sent me a letter", it was "Aaah! Monster! Don't eat me!"

But the owl was plenty cool.

And sent back to Professor Gordon, explaining that the owl must have gotten the wrong address with a letter.

"You know, Professor Gordon was one of the best Quidditch players in the world before he retired," Nya told Jay. "I wish I had enough money to get a proper broomstick for myself…"

The screaming boy returned, no longer screaming, holding the hand of Cole and leading him in the direction he came from when he was screaming.

Jay and Nya couldn't help but stare at the boy, eyebrows raised in confusion, as he was talking, very seriously, to the Hufflepuff boy, who seemed just as confused at the strange turn of events.

Prologue: Cole

Cole was woken up from his rest twice: Once when that Slytherin kid came by to try and offer him cookies, which were rejected, then by the panicked screaming of a first-year, crying that someone had been possessed.

The boy was grabbed by the shoulders by the fourth-year and told to calm down and breathe.

For some reason, Cole had the idea that the poor kid was Muggleborn and had just seen a witch or a wizard having a weird day for the first time.

"Now, what's going on?" Cole asked once the boy had calmed down enough speak.

"He's possessed," the boy repeated. "He gave me some Chocolate Frogs and I showed him a card, then the room got cold and everything, and then his voice got all deep and he told me… he told me…"

The boy started crying again.

"It's okay, it's okay, what's your name, buddy?"

"Lloyd."

"I'm Cole. Now, start at the beginning."

Lloyd took a deep breath. "I was looking for the first-years' car, when Zane told me that it would be okay if I sat with him for a while, and he gave me some Chocolate Frogs, you know, the ones that jump, and then I showed him a card, and then the car got all cold and then, his eyes started glowing and his voice got all deep and demonic and stuff, and he told me that I was destined to kill my dad or something, and then I ran out of there to get help!"

Cole didn't know anybody named Zane, but he didn't know everybody at Hogwarts, so he simply nodded and took the kid's hand. "Okay, why don't you show me to your friend and I'll see what we can do to help him. Maybe he just caught something during summer."

Lloyd nodded. "Okay."

Lloyd lead Cole through the train, through the car that contained the Slytherin kid who tried to give him some cookies, eating them with a Ravenclaw girl, both of whom were giving him and the kid odd looks as he kept talking about how he was looking for the first-years' car and Cole wondered to himself what could possibly be wrong with this mysterious Zane person.

When they finally arrived at Zane's car, Cole didn't find some possessed person acting like a possessed person, but instead, a light-haired boy with ice-blue eyes, looking sad and alone.

"Hello?" Cole walked in with Lloyd. "Are you Zane?"

The other boy nodded shyly. "Yes, I am."

Lloyd hugged Zane, who seemed overall surprised at the gesture, but hugged back. "I apologise for scaring you. I tend to black out at times, and I have no memory of what I do or say at those times."

"Sorry for putting the card in your eyeball," Lloyd sobbed.

"It was not the card, Lloyd. Don't blame yourself."

Cole turned around to go back to his car, when the train stopped.

They had arrived at Hogwarts.
