Story:

When Elena, Caroline, Matt, Tyler, Damon, Stefan, Alaric, Klaus, Elijah, Bonnie, Kol and Kai pick up their newspaper they hardly expected to see an ancient looking envelope. They all opened their letters not knowing what to expect, at first Caroline thought it was Klaus with some lame attempt at getting with her. Shortly after reading their letters they decided that whoever got one should meet at the Salvatore's house.

Bonnie nearly shrieked when she saw Kai there, he was grinning from ear to ear, "It looks like were going to Hogwarts together" he said full of enthusiasm.
Damon finally spoke up, saying there was a handwritten letter included in this envelope, it said that the Dark Lord (whoever that was Damon thought) was back and that the school needed extra protection and who better than the one who defeated Silas? Elijah, Elena and Stefan thought this idea was a little sketchy, but to everyone's surprise Kai and Bonnie were the most excited. (Obviously since their witches and this was a witchcraft school)

On each of their letters it specified whether they were to become an assistant teacher or would they become a student.

Kai Parker: Assistant Teacher
Tyler Lockwood: Student
Caroline Forbes: Student
Elena Gilbert: Student
Matthew Donovan: Student
Stefan Salvatore: Student
Bonnie Bennett: Assistant Teacher
Damon Salvatore: Assistant Teacher
Kol Mikaelson: Student
Klaus Mikaelson: Assistant Teacher
Elijah Mikaelson: Assistant Teacher
Alaric Saltzman: Assistant Teacher

Caroline laughed so hard that she could barely stand; Kol was the one who really noticed at first and asked why she was laughing, at this point she had everyone attention. "Klaus is a teacher and you know the rules, teachers can't flirt with students, please sign me up right now so I can be free" Caroline shouted with glee.
-"Don't worry love, I'm only an assistant teacher, and as Bonnie likes to call it, I will find a loophole" he said with a smirk on his face. By then Caroline has stopped laughing and had a concerned look on her face.
"Well that was awkward, let's get packing already" Damon chirped in

Alaric Saltzman looked through the list of items he needed to retrieve, a wand, a book of monsters, where would they get all of these things? Luckily Kai and Bonnie knew just the place. Elena thought to herself how close Bonnie and Kai were considering the fact that he stabbed her multiple times.

After packing items they could actually pronounce, the two lead them to Diagon Alley, no one questioned how they knew this place, they just did. Kol insisted that Caroline go with him to find a pet, he wanted a bat. Klaus warned Caroline never to be alone with Kol but what did she care what he thought of her, she agreed.

Caroline and Kol went to the pet store, and that's where Kol laid his eyes on her, "Caroline, I've found her, she magnificent"
-"Kol, it's a damn bat" Caroline looked at him like he was crazy.
-"It's my bat Caroline, I shall name her Bat.
Caroline was just laughing at this point, so hard that she actually fell backwards. Someone caught her though, she was slightly embarrassed and was still laughing.
-"OMG, I'm so sorry"
-It's fine, I've never seen you before, my name's Dean Thomas"
-Hi Dean, my name's Caroline and this is my Kol, he's buying a bat"
-" I thought we were more than friends Caroline" Kol said as he stroked Bat
-"In your dreams; anyways nice meeting you Dean Thomas but I'm afraid my FRIEND and I must be going"

Bonnie and Kai had gone to get the necessary textbooks, when they walked into the shop they almost dropped, they had never seen so many grimoires in one place, they wanted to buy them all. Interrupted by their gazing by two twins, two redheaded twins. "I'm George and he's Fred and you two look lost" Bonnie broke out of the grimoire trance first, realizing people were standing and talking to her. "Oh um hi, sorry we've never seen so many spell books in one place, we're kinda new" Fred and George laughed and Kai finally broke free introducing himself. Fred and George continued to make conversation. "So what year are you guys? Said Fred directing his question, "We're both Assistant teachers" Kai replied. "You guys are super young, you must be good at witchcraft" said George, with that the two twins left.

Meanwhile, Damon, Stephen and Elena went to pick out wands. When they walked inside Olivander's they saw a redheaded boy and a boy with a scar on his forehead. "Nice Scar" Damon said. The scar headed boy looked confused because everyone knew about the scar and who he was but it was refreshing to have someone knew. "Thanks, I'm Harry Potter and this is my friend Ron Weasly, he needs a new wand." "I'm Elena, this is Stefan and Damon, we too are shopping" "By all means go ahead of us" Ron said gazing at Elena. Stefan and Damon glanced at each other, they knew Ron looked at Elena and they knew that look anywhere because that's the look they give her. Officially creeped out by the two of them, the Salvatore's and Elena left the shop and got sweets.

Matt and Tyler had already found their archenemies in a matter of 5 minutes, their names were Crab and Goyle, these kids were the opposite of Matt and Tyler, they were their antagonist, luckily Kol and Caroline got there before they could start a fight against wizards.

Of Course, Hermione and Ginny were in the book store, where else would they be? The bell on the door ringed and entered Alaric and Elijah, they picked up a whole bunch of books and potions. Hermione went to grab the last: Potions book as did Elijah. They laughed uneasily and Hermione flipped her hair behind her shoulder, Elijah realizing how beautiful she was, got distracted and started looking at her beautiful hair. Hermione quickly snatched the book and ran off to find Ginny. Alaric walked up behind Elijah "Dude, you just got played" Elijah laughed and watched a Hermione purchased the book, as she was leaving she waved and blew a kiss to Elijah. She would do anything for her books.

That leaves us to deal with Klaus, angry from watching Kol and Caroline bond over a bat he walked off to look at the art shop, he was less than impressed "You'd think they have a better art shop for wizards" He said aloud. Then Draco Malfoy turned around and asked him what his deal was bashing art. Klaus was rather intrigued by this young fellow (obviously) Draco eventually stopped waiting for a response and joined his father. Klaus feeling a bit embarrassed walked out with his head low.

The met at the center of the alley, all their heads were turned towards Kol where Bat rested on his shoulder, Klaus just wondered how they were related the same goes for Elijah. Kai was curious about Bat, he went to pet her when she clawed his hand. He hissed at the bat. "Turns out we can compel animals as well, so don't go touching Bat without my permission" he said as he glared at Kol.

Matt laughed "Of course Kol will compel a bat as a friend. They worked their way to Platform 9 3/4. The all got a cart together, but on their way to the enlarged cart Caroline bumped into Draco Malfoy, he looked at her and asked if she wanted to join him in his cart, she agreed as did Kol and Klaus. It was pretty uncomfortable sitting with all three guys who potentially liked her, and to make matters worse Dean Thomas came and sat with Malfoy. Caroline made an excuse about how she had to go to the bathroom. "Don't be long darling" Kol yelled after her.

Other than Matt and Tyler raiding the trolley of sweets and Kai practicing magic the try and undo the bat's compulsion they had a pretty normal train ride for once.
