At Platform 9 3/4, the Hogwarts Express was beginning its departure from the station with Devon, Harry, Ron, Hermione, and all the witches and wizards onboard to begin their journey back to Hogwarts School of Witchcraft and Wizardry. Just as the train started to roll along the tracks, Molly Weasley runs along the platform with Scabbers in her hands, trying to catch up with the train. Apparently, Ron had lost his pet and his mother was rushing to get it back to him.

"Ron! Ron!" Molly exclaims

Catching up with her son, Molly hands Ron his pet rat as he leaned out through the open window with Devon, Harry, and Hermione.

"Oh, for goodness sake! Don't lose him!" Molly exclaims

Soon, the Hogwarts Express leaves the station and was on its way.


Inside the train, the Keyblade Wielder and the Wizarding Trio walked from one passenger car to the next, trying to find a compartment that was free since everywhere else was full. Devon lead the trio with Harry, Hermione, and Ron following behind him.

For their trip back to Hogwarts, Harry was now wearing a grey jacket with double stripes going from his shoulders down the sides of his sleeves, a red shirt underneath, and navy-blue jeans. Hermione wore a pale blue long-sleeved shirt with red, orange, blue, and black stripes, and brown jeans. And Ron wore a dark brown jacket with a multicolored shirt underneath and dark grey trousers.

"I didn't mean to blow her up. I just... I lost control." Harry says

"Brilliant." Ron chuckles

"Honestly, Ron, it's not funny. Harry was lucky not to be expelled." Hermione says

"I think I was lucky not to be arrested, actually." Harry says

"I still think it was brilliant." Ron says

"Guys, remember, it was an accident. I'm sure it's not the first time the Ministry had to deal with witches and wizards who lost control of their magic every now and then." Devon says

Hermione looks into the cabin on their right and saw that there was only one person inside with plenty of room for them.

"Come on. Everywhere else is full." Hermione says

Hermione slides open the door and the quartet enter the compartment and take their seats. Ron and Hermione sat together on the left-side of the cabin while Devon and Harry sat on the right next to the stranger. He appeared to be asleep as he was covered up with his cloak.

"Who do you think that is?" Ron asks

"Professor R.J. Lupin." Hermione says

"You know everything. How is it she knows everything?" Ron asks looking at Hermione on his right before looking at Devon and Harry

"It's on his suitcase, Ronald." Hermione says pointing up at the suitcase that was on the rack above Devon and Harry side of the cabin

"Oh." Ron says

Devon and Harry look over at Lupin, wondering if he was really asleep and not listening to their conversation.

"Do you think he's really asleep?" Harry asks

"Seems to be. Why?" Hermione asks

Devon and Harry both shared glances with each other and the Keyblade Wielder nodded his head. Rising up from his seat, Harry went over to the door of the cabin.

"There's something we got to tell you." Harry says

Sliding the door closed, Harry proceeded to tell his friends everything that he and Devon heard from Arthur Weasley.


Later that night, the Hogwarts Express was now halfway through its journey to the magic school as it traveled alongside the left-side of a large lake. In their compartment, Harry and Devon explained what they knew about Sirius Black to Ron and Hermione.

"Let me get this straight. Sirius Black has escaped from Azkaban to come after you, Harry?" Ron asks

"Yeah." Harry says

"But they'll catch Black, won't they? I mean, everyone's looking for him." Hermione asks

"Sure. Except no one's ever broken out of Azkaban before." Ron says

"Until now." Devon says

"And... he's a murderous, raving lunatic." Ron says

"Thanks Ron." Harry says in a sarcastic voice

Suddenly, the Hogwarts Express shakes and screeches to a halt with the brakes squeaking loudly on the tracks.

"Why are we stopping? We can't be there yet." Hermione asks

"No. We're not." Devon says

Devon and Harry rise up from their seats, open the door to the compartment, and look up the small passage. The other students poked their heads out of their compartments, wondering what happened. The train shook again with a loud rumble and the Keyblade Wielder and wizard boy were thrown back into their seat as they fell backwards. The door to the compartment slid closed.

"What's going on?!" Ron asks nervously

"Don't know. Maybe we've broken down." Harry says

"Really? When was the last time the Hogwarts Express ever broke down?" Devon asks

Then, the lights in the compartment flickered and went out. Ron scoots over towards the window to look outside, accidentally stepping on Hermione's feet in the process.

"Ouch! Ron, that was my foot." Hermione says

Ron places his right-hand against the glass window and gazes out into the night, feeling the something evil was lurking in the rainy weather.

"There's something moving out there." Ron says

The train had stopped on the stone bridge over the Glenfinnan Viaduct and remained there over the next several minutes. Everything fell eerily silent.

"I think... someone's coming aboard!" Ron whispers

The train shook again for a third time, only slightly, and an unnatural cold filled the air. Everyone shivered as their hot breath could be seen.

"Did it just get cold in here all of a sudden?" Devon asks shivering

The Keyblade Wielder and the Wizarding Trio soon looked toward the compartment window and watched as ice began to appear, spreading from the left and crackling softly. Even the liquid in a bottle near Lupin, which was supposedly his drink, froze up in ice. Then, the train shook again more violently.

"Bloody hell! What's happening?!" Ron asks frightened

Suddenly, a dark, wraith-like creature appears outside the compartment, approximately 10 feet tall with a grey, decaying body, like a decomposing corpse, completely covered in a dark hooded cloak of long ripped black cloth, which flowed in the air, and a gaping large hole where the mouth should've been. It was a Dementor, one of the foulest dark creatures ever to inhabit the Wizarding World.

Gliding over the floor, the dark creature gestures to the door with its slimy, scabbed right-hand and the door slowly slides open with its bony, decomposed fingers crackling around the side. The Dementor floats at the doorway, gazing into the compartment with a rattling breath that made a distorted whooshing sound, like it was trying to suck more than air out of the room.

First, it looks over at Ron and Hermione on its left as they became paralyzed with fear. Hermione gasped, Crookshanks reared back and snarled, and Scabbers squeaked loudly with fright, hiding away in Ron's jacket. Then, the Dementor turns its gaze right towards Devon and Harry, sensing their presence and their emotions. Before neither the Keyblade Wielder or wizard boy could do anything, they both groaned as a distortion formed in their faces and the air near them, which flowed towards the Dementor. They felt a tight grip in their chests, rendering them weak and helpless, and they could hear their own heartbeats. Devon felt so weak he couldn't even summon his Keyblade. The Dementor was sucking the life out of him and Harry, trying to steal their souls!

Just as things looked grim for Devon and Harry, Lupin's eyes snap open and he stands up with his wand, which was 10 1/4" long, made of cypress with a unicorn hair core, pointed at the Dementor, casting a spell that shot forth a burst of bright silver light from the tip of his wand with a deep whirring sound. The dark creature retreats from the compartment, shrieking loudly from the light. As Lupin drives the Dementor away, the pupils in Devon and Harry's eyes dilate and shrank, narrowing as they both fainted with Devon falling backwards against the seat and Harry falling on top of him. And as they passed out, the two boys heard a woman screaming, each different from the other, yet familiar.

"Harry...!" A woman screams

"Devon...!" Another woman screams

The screams faded away as the train's whistle blew.


Sometime later, the Hogwarts Express was on the move again with the lights restored, continuing with its journey. It was a while before the Keyblade Wielder and wizard boy regained consciousness with Hermione's voice echoing in their ears.

"Harry?! Devon?! Are you alright?!" Hermione says

Harry awoke first as his eyes slowly opened, laying over half of his seat, and then Devon woke up laying over the other half with his back against the window.

"Mmm... Uhh..." Devon groans

Harry's glasses fell off his face when he fainted, but Hermione had them in her hands and she gave them to him.

"Thank you." Harry says

Devon and Harry straightened themselves as they recovered little by little. Devon placed his right-hand on his chest right where his heart was, still reeling from the effects of nearly having his soul stolen.

"What... What happened?" Devon asks

Lupin's right-hand extends out to the two boys with a chocolate bar in his hand, offering it to them.

"Here, eat this. It'll help." Lupin says

Devon and Harry stared down at the chocolate bar for a moment, then glanced up at Lupin, getting a good look at him.

Remus Lupin was a 33-year-old Half-blood British/Irish Wizard with a calm, kind, and good-natured personality. He was 6'2 with light brown hair flecked with grey, green eyes, a pale face with premature lines, a thin moustache, and scars cutting across his face, wearing an extremely shabby set of wizard's robes that had been darned in several places.

"It's alright. It's chocolate." Lupin says

Devon and Harry both took a thick piece of chocolate and took a bite. Then, they looked over at the door, where the Dementor once was.

"Wha-what was that thing?" Harry asks

"It was a Dementor." Lupin says

"A Dementor?" Devon says confused with the name

"Yes, one of the guards of Azkaban. It's gone now." Lupin says

"What was it doing on the Hogwarts Express?" Devon asks

"It was searching the train for Sirius Black." Lupin says

Lupin looks Devon over and right away he noticed his Kingdom Hearts chain necklace, more importantly he saw the faintly glowing heart-shaped crystal that was hanging just below the base of his neck.

"If I had to venture a guess, I'd say you're a Keyblade Wielder, aren't you?" Lupin says

"That's right. How'd you know?" Devon asks

The man points his right-hand to the blue crystal heart.

"I've seen that symbol before during my time in Hogwarts. It is associated with the Keyblade Wielders and a very ancient realm called Kingdom Hearts." Lupin says

"Kingdom Hearts?" Ron asks

Ron and Hermione shared glances with each other.

"You mean the heart-shaped moon that Devon talked about?" Ron asks

"Yes. The heart of all worlds, including this one. Very, very few people know of its existence, including Dumbledore and myself, and Keyblade Wielders were its sworn protectors. The Keyblade Wielders were greatly revered as heroes and friends among many witches and wizards, including dozens of magical creatures. Truly remarkable people. Very strong, very powerful, in terms of magic. I, myself, have come to respect them a great deal." Lupin says

Devon smiles and extends his right-hand out to the friendly wizard.

"Well, thanks for the save, uh... Lupin, right?" Devon says

Lupin smiles and shakes Devon's hand.

"Anytime. Now, if you'll excuse me, I need to have a little word with the driver." Lupin says

Rising up from his seat, Lupin slides open the door to leave, but not before turning back to Devon and Harry.

"Eat. You'll feel better." Lupin says pointing to the chocolate in their hands

After having said that, Lupin closes the door and heads up to the front of the train. Devon and Harry both took another bite of their chocolate bars, then turned to Ron and Hermione.

"What happened?" Harry asks

"Well, you and Devon sort of went rigid. W-We thought maybe you both were having a fit or something." Ron says

"And-and did with of you two... you know... pass out?" Harry asks

"No. I felt weird, though. Like I'd never be cheerful again." Ron says

"But someone was screaming. A woman." Harry says

"I heard it, too. Only... I heard my name." Devon says

"No one was screaming, guys." Hermione says

The Keyblade Wielder and wizard boy stared at their two friends, then shared confused glances with each other before staring outside as the rain continued to hit the window. They were deep in thought over what just happened with the Dementor. Both of them heard a woman screaming their names prior to fainting, yet they felt familiar somehow.


The rain was still pouring by the time Devon, Harry, Ron, Hermione, and the other students arrive at Hogsmeade station and they traveled to Hogwarts by horseless carriages.

Once they were at the castle, the Keyblade Wielder and the Wizarding Trio sat at Gryffindor's table inside the Great Hall and watched with the other students as the Start-of-Term Feast began with a song from the Frog Choir.

(Something Wicked This Way Comes - Starts)

Twenty-three students stood and sang together at the back of the Great Hall with five students in the front holding large brown toads in their hands as they croaked to the beat, one female student on the left playing a tambourine, a male student on the right pounding a large drum, and Professor Flitwick as the leading conductor.

Frog Choir:

Double, double, toil and trouble;
Fire burn and cauldron bubble.
Double, double, toil and trouble;
Something wicked this way comes!

Eye of newt and toe of frog,
Wool of bat and tongue of dog,
Adder's fork and blind-worm's sting,
Lizard's leg and howlet's wing.

Double, double, toil and trouble;
Fire burn and cauldron bubble.
Double, double, toil and trouble;
Something wicked this way comes!

In the cauldron boil and bake,
Fillet of a fenny snake,
Scale of dragon, tooth of wolf,
Witches' mummy, maw and gulf.

Double, double, toil and trouble;
Fire burn and cauldron bubble.
Double, double, toil and trouble;
Fire burn and cauldron bubble.
Double, double, toil and trouble;
Fire burn and cauldron bubble.

Something wicked this way comes!

(Something Wicked This Way Comes - Ends)

Everyone applauded the performance of the Frog Choir as they step down and the Headmaster, Professor Dumbledore, who was now wearing pale light blue robes and a round wizard cap, moves up to the stand to make his announcement.

"Welcome, welcome to another year at Hogwarts. Now, I'd like to say a few words before we become too befuddled by our excellent feast. First, I'm pleased to welcome Professor R.J. Lupin, who's kindly consented to fill the post of Defense Against he Dark Arts teacher. Good luck, Professor." Dumbledore says

Dumbledore turns to his left and gestures his hand to Professor Lupin as he sat next to Professor Snape on his right and another wizard on his left. Lupin rises up from his seat and takes a bow as the students and his fellow staff members gave him a round of applause.

"Of course. That's why he knew to give you and Devon the chocolate, Harry." Hermione says

"Potter. Potter!" A voice calls

Devon, Harry, Ron, and Hermione look behind them at Malfoy as he sat at Slytherin's table, calling Harry's name.

"Is it true that you and Devon fainted?" Malfoy asks teasingly

Pike, a 13 year-old male Slytherin student who was a British/Irish Pure-blood wizard with light skin, brown hair and blue eyes sat next to Malfoy on his left as part of his gang mocked a sigh with his left-hand on his head, pretending to be Harry as he fainted from his encounter with the Dementor.

"I mean, you both actually fainted?" Malfoy says

"Shove off, Malfoy!" Ron says

The Keyblade Wielder and the Wizarding Trio turned away from the bullies and faced each other.

"How did he find out?" Harry asks

"Just ignore him." Devon says

Focusing back on Dumbledore, the quartet listened to the rest of his announcements.

"Also, Professor Silvanus Kettleburn, our Care of Magical Creatures teacher for many years, has decided to retire in order to spend more time with his remaining limbs. Fortunately, I'm delighted to announce that his place will be taken by our very own... Rubeus Hagrid." Dumbledore says

Dumbledore turns to his right and gestures over to Hagrid as he sat between Professor McGonagall on his left and Professor Flitwick on his right. McGonagall nudges Hagrid's left-side with her elbow and the Half-giant rises up from his seat, causing the table to shift slightly and the plates and chalices to clatter loudly. Many of the students, including Devon, Harry, Ron, and Hermione, gave him a nice, long round of applause, whistling, whooping, and cheering.

"All right, Hagrid!" Devon cheers

Dumbledore looked over at Gryffindor's table and saw the Keyblade Wielder with Harry and his friends and smiled as he made his next announcement.

"And once more, our world plays host to it's very special guest, one who has saved our wonderful school and it's students from tragic disaster. So now, let us all give a nice, warm welcome to the honorary savior and eternal friend of witches and wizards alike: Devon, the Legendary Keyblade Wielder, who has returned for yet another magical year at Hogwarts." Dumbledore says

All those in Gryffindor, Hufflepuff, and Ravenclaw's table cheered, whistled, whooped, and hollered as Devon name was announced. Devon looked around at the young witches and wizards, then rises up from his seat, waving his right-hand around with a smile on his face. The cheers for him were almost deafening as they echoed loudly across the Great Hall. Devon soon sits back down as Dumbledore continues on with his speech.

"Finally, on a more disquieting note, at the request of the Ministry of Magic, Hogwarts will, until further notice, play host to the Dementors of Azkaban until such a time as Sirius Black is captured." Dumbledore says

The students murmured amongst themselves while Devon and Harry both listened to Dumbledore's words with much heed and interest as he continued on with his announcement.

"The Dementors will be stationed at every entrance to the grounds. Now, whilst I've been assured that their presence will not disrupt our day-to-day activities...a word of caution. Dementors are vicious creatures. They will not distinguish between the one they hunt and the one who gets in their way. Therefore, I must warn each and every one of you to give them no reason to harm you. It is not in the nature of a Dementor to be forgiving." Dumbledore says

Dumbledore holds up both his hands with his index-fingers raised up as he continues speaking.

"But, you know, happiness can be found, even in the darkest of times..." Dumbledore says

The Headmaster waves his right-hand over a tall white candle on his right and the burning flame disappears from the flick.

"...if only one remembers to turn on the light." Dumbledore says

Waving his hand back over the candle, the flame reappears and burns brightly.


Once the feast was over, Devon, Harry, Ron, Hermione, and the rest of Gryffindor house walked together through the halls of the castle and soon made their way into the Grand Staircase. Seamus made his way up changing stairs as they turned from the left-side of the room to the right and approached the large portrait with the Fat Lady as she was singing soprano with a clear wine glass in her right-hand, trying to shatter it with her voice. Seamus speaks the password to the Fat Lady to gain access to the Gryffindor Common Room, but she refused to open up.

"Fortuna Major." Seamus says

"Ah, bup, bup, bup, bup." The Fat Lady says holding up her left-hand

Devon, Harry, and the others reach Seamus at the top of the stairs, and he turns to the two boys.

"Here, listen. She just won't let me in." Seamus says

Harry steps up and speaks the password.

"Fortuna Major." Harry says

"No, no, no, wait. Wait. Watch this." The Fat Lady says holding out her left-hand

Clearing her voice, the Fat Lady sings her soprano again.

"Ah, ah, ah... ah!" The Fat Lady sings

The Fat Lady screams a high note, making Devon, Harry, the Gryffindors, and the other paintings around her cover their ears. This lasted for seven seconds until her high note started to waiver. The Fat Lady then smashes the glass on the wall behind her on her right and acts surprised as she gasps, pretending that she had actually shattered the glass with her voice.

"Amazing! Just with my voice." The Fat Lady says

"Fortuna Major, please." Devon says

"Yes, all right. Go in." The Fat Lady says

The portrait slowly swings open inward, and the round passage was now open for the group of Gryffindors.

"Thank you." Devon says

Everyone enters the Gryffindor Common Room and made themselves comfortable.

"Plebs." Neville mutters

"I can't believe she's still doing that after three years." Seamus says

"I know." Harry says

"She can't sing." Harry and Seamus say in unison

"Exactly." Harry says

"Exactly. Unbelievable." Seamus says


Up in the boys' dormitories, Devon, Harry, Ron, Seamus, and Neville sat around in their beds, trying special magic jellybeans. Devon had taken off his jacket and wore only his black shirt and his jeans. He sat to the right of Harry, who wore only his bluish-gray shirt. On his right was Ron, who wore a brown and white hat with pigtails, a tan-checkered shirt, and plaid pajama pants. On their left, Seamus wore red pajamas and Neville wore light blue pajamas. Seamus was given a jellybean first.

"Oh, green. That's a monkey." Ron says

Upon eating the jellybean, Seamus began making actual, authentic chattering monkey sounds, flapping his arms and leaning over to Neville on his left and Devon, Harry, and Ron on his right.

"What is that?" Ron laughs

"You call that a monkey?" Harry laughs

"Ha! You should've given him a chicken the way he's flapping his arms." Devon laughs

"Do not give him one again." Ron says

Ron takes out another jellybean, this one yellow, and tosses it over to Neville across the room.

"Hey, Neville, try an elephant." Ron says

Neville catches the jellybean and eats it, then starts making authentic trumpet sounds of an elephant. Seamus grabs a jellybean on the dresser he leaned on behind him on his left and tosses it over to Ron.

"Ron, catch!" Seamus says

"Oh, yeah." Ron says

Ron catches the jellybean, eats it, and he starts making authentic growls and roars of a lion. The boys ooh-ed, ahh-ed, and laughed.

"I think we have a winner." Harry says

Ron saw Harry pick up a red jellybean and stretches his left-hand out to stop him.

"Oh, don't try one of them!" Ron says

He was too late as Harry placed the jellybean in his mouth and chewed on it.

"Oh, no!" Ron says

The boys groaned and laughed. Soon, Harry winces his eyes shut as steam shoots out from his ears with a whistling sound.

"Look at this!" Ron says

"Ha ha! Look at his face!" Devon laughs pointing at Harry with his right-hand across his body

While the boys were all having fun inside the castle, outside dozens of Dementors floated about in the air in the rain as the thunder crashed and the lightning illuminated their cloaked forms. Things at Hogwarts would only get even more interesting in the coming days.


Author's Note: There's been Snakes on a Plane, Ants on a Plane, and now there's Dementors on a Train! Devon and Harry have survived their encounter with the soul-sucking Dementor thanks to their new friend, Professor R.J. Lupin, and now its back to Hogwarts for Year 3. Next up: Classes in Divination, Magical Creatures, and Defense Against the Dark Arts. To anonymous(guest), the Raizard and Voidture, and Mortoid are good. For the Obsidoraptors, I'll need more info on them. As for their names, Scorpus, yes, Cobrix, yes, Wraith, no, Psychor, no. The Dark Slayer... Mmm... I think it should be given a different name, same for the beta and the fourth Obsidoraptor. Now, for the list of Heartless and Unversed you've given me already, I'll need some info to determine which worlds they are to appear. I've seen a lot of Heartless and Unversed, but I've yet to see any Nobodies. Let me know what you guys think. No flames please. Hope you guys like and don't forget to review!
