This story happens during Year Three Harry Potter. Some of this you may recognize from the book but with my own twist. This idea was a dream I had after reading a Rise of the Guardians FanFiction and watching Harry Potter and the Prisoner of Azkaban. I hope you enjoy reading this.

Chapter One: The Calling

Jack look on with a smile on his face, it was summer in the northern hemisphere and he had come down to the Southern to spread the winter cheer, though it doesn't get cold enough to spread snow all over there was still fun in this type of winter as well. But at the moment Jack was watching a group of children play in the snow. It was a school group that was on an outdoor education trip to Falls Creek and were currently Cross Country Skiing. He smiled as a young girl got a teacher with her snow ball.

"Hey look at that?" Called out one of the kids pointing to the sky, Jack looked up to see what the kid saw. The Northern Lights.

"Oh no" he murmured

"They look like the Southern Lights." Called another kid.

"They can't be." Called the girl who hit the teacher "they're the wrong colour, and if they were they're coming the wrong way, they're coming from the north."

"But it can't be the Northern for we're in the south."

"Let's just say it's an Aurora and leave it at that?"

"Oh man I have got to tell North" Jack said "Can you remind me wind? And wind… TAKE ME TO NORTH'S"

E. Aster Bunnymund raced straight to the fire-place in the globe room, he hated it. He HATED the cold. He needed to get warm he really did, he was as humans put it cold-blooded can think or do anything in the cold. He looked around to see if anyone else was there, but besides from Nickolas St. North he was the first one there.

"…Sector 5 head out, three more in Brittan.."

"Here comes the sheila." Bunny shock his head as Toothiana came in to view closely followed by Sanderson. "Hey North can ya tell us why ya called us?"

"We wait for Jack, then I vill tell only once then" replied the big guy.

"Where is the frostbite anyway, isn't summer?"

"It is in the Northern Hemisphere." Came the reply from the winter spirit himself. "But winter is also in the Southern Hemisphere, just at opposite times. I thought you knew that?"

"Of course I did, I just didn't know ya also went to the Southern Hemisphere"

"Of course who else could do what I do? Oh before I forget" Jack turned to the Cossack "Are kids suposta see the Aurora?"

"Why do you ask, Jack?" asked Tooth curious.

Jack shrugged his shoulders "Just because some kids did."

"Oh well Phil will fix" North said with ease, a Yeti somewhere behind him groaned "but that's not important right know, Manny wants to talk to us."

"About what?" Asked Bunny.

"I don't now I haven't read yet."

"Read what?" asked Tooth as Sandy created a question mark above his head.

"A letter that Manny said to read when we are all here. He sent a box as well."

"Well were all here ya gummpy, ya can read it now." Bunny said with cheek, Jack gave a small laugh.

North rolled his eyes at the twos antics, he walked over to were a small looking treasure chest that looked like it was made out of moonstone and silver, with an envelope sitting on top with the Guardian's symbol printed on the front.

"You said a box that's a treasure chest" Jack said with disbelief "What's inside?"

"Let's read letter shall we?" Asked North as he opened the envelope.

"I'll read!" said Tooth as she took the letter of North.

"My Guardians. I have noticed that there is a large group of children in danger to a great Shadow. The Shadow is over a school that is located in England almost in Scotland."

"A School?"

"Jack shut up and listen will ya"

"This school is not like most this is a school that teaches magic." North's eyes lit up with wonder at that. "The name of this school is Hogwarts School of Witchcraft and Wizardry." Jack fell of the back of the chair he was sitting on as Bunny was sitting on the actual seat.

"Hogwarts?" He asked in disbelief.

"Jack you know this school?" Asked North with wonder, seeing he had only heard it a few times before.

"Um yer I've spread some snow there from time to time." Jack said as he got himself off the ground. "I haven't been there in three years but."

"Can I keep reading please?" Tooth was excited seeing she has already read ahead.

"Go ahead sheila."

"My Guardians I want you to go undercover to keep the children save from this Shadow and to banish this Shadow as most children has the school as a safe haven, and lets them to be themselves. Your cover is foster family. Nickolas St. North and Toothiana you will be playing as the parents." At this Bunny looked up to Jack and Sandy.

"Sanderson Mansnoozie you will be playing the oldest but second adopted son. E. Aster Bunnymund you will be playing the middle and first adopted son. I should also mention that there will be Professors that will use your first name not your middle." Bunny groaned he didn't like others using his first name as it reminds him of his mother as she picked it out for him.

"Hey Bunny what is your first name?" Asked Jack.

"Why do you want to know frostbite?" asked Bunny a little unset with this placement.

"I want to hear it from you not the Professors."

'Okay that was a good point and thoughtful' thought Bunny before he answered "Emerson. Let's hear what MiM what's you to play."

"Jackson Frost you are playing the youngest and last adopted son. The three of you had been home-schooled and have never been to a school before, but as your parents have taken up a place in teaching at Hogwarts you had to join. The Sorting Hat -you will know when get there- will sort you in respective House and year.

"Nickolas you are taking up the position of History of Magic Professor, which I know you will love and do better to gain the student's attention better than the last. Toothiana you will be taking up the place of Muggle Studies Professor. Muggle is their term for people with no magic blood.

"In the case that I have provided are your wands that you will need. Jackson you can use you staff as well as the wand provided, as you can be passed as an element based wizard that can use staffs and your staff can also double as your broom. You will know which wand is yours when you see them but I will tell you what they are made out of. Nickolas your wand is Apple with a Phoenix feather core, Toothiana yours is Aspen with a Unicorn Hair core, Sanderson yours is Alder with also a Unicorn Hair core, Aster yours is Fir with a Phoenix feather core and Jackson yours is Beech with also a Phoenix feather. Also in the case is a mixture of my own creation, colour coordinated to who needs to drink which; Nickolas red, Toothiana pink, Sanderson yellow, Aster green and Jackson blue.

"I also suggest that you all should stay at The Leaky Cauldron in London for the last few weeks of the Summer Holidays to get use to the Magic Community and collet school supplies, I suggest the basic first and get the books you need after the sorting.

"The best of luck Man in the Moon" Tooth looked up to the others "Well I can't wait."
