A/N: Thank you for deciding to click on my story, this will be a Hogwarts AU and the main ship will be Elsanna (not sisters) For this world, lets imagine that everything in the Harry Potter books happened, but Snape is still alive but cold towards Gryffindors and Dumbles is still alive. Also I changed some of the characters' last names as I find it fits more, and if you know where they are from then have a cookie! ;) Hope you like this chapter.
Disclaimer: I do not own Harry Potter, Frozen, How to Train Your Dragon, Tangled, Rise of the Guardians or any of their characters, big surprise there ;) I only own my plot and that is about it.
The day hadn't really started off well for Anna Menzel; she had woken up later than usual and had to fight her second best friend, Merdia Macdonald, for the bathroom whilst trying to get her other best friend, Rapunzel Moore, out of her own bed. By the time she had got into the bathroom they were already running late.
With scampering feet the trio made their way down the stairs of the Gryffindor girl's dorms. They ran through the portrait and down the flights of stairs until they eventually made it to the Great Hall with about ten minutes of breakfast left.
Their Ravenclaw friend, Hiccup Baruchel, clicked the stopwatch which he had conjured and looked at the time, tisking lightly.
"You're getting later every year girls."
"Yeah, well you try sharin' a bathroom with these two girlies; I have to get up at damn near five to get everything done in time!"
"Oh that's rich Merdi! It takes you years to tame that wild thing!" Rapunzel shouts back, leaning back from Flynn who had greeted her with a kiss. Merdia huffed indignantly and tossed a strand of her fiery hair over her shoulder.
"Well at least I know how to wake up Punz, anyone would think tha' yer sleepin' beauty!"
Rapunzel's response was cut short when Anna interrupted their upcoming argument.
"Shall we just say that we are all lazy assed witches and be done with it?" she sighed, stirring her cereal and watching as it continued to soak in the milk.
"Hey, you okay Anna?" Hiccup asked, budging her shoulder lightly.
"Yeah, its just… its our fifth year and we are taking our OWL's for our future, and I don't even know what I want to do this weekend let alone when I'm an adult!"
"Hey, its just fifth year jitters, it will wear off, you'll see." She smiles and thanks Hiccup, but looks down to her bowl almost immediately. Her friends glance nervously at each other over her head, normally she is fully of happiness and excitement, but she did get like this around the start of each year since third year. They had got used to it, but it still sucked to see her so down.
They then continued in their conversations, trying to cheer the second red head up
Anna felt something then, like someone was watching her.
"Hey," there was a tap on she elbow, she looked up and smiled somewhat questioningly at Rapunzel, who nodded across the hall, "check out who's looking at you."
Anna frowned, confused, but looked up anyway. And when she did, she felt her heart stop.
Looking right back at her, sky blue locking with ocean blue, all the way from the Slytherin table, was Elsa Arendelle.
Elsa Arendelle, she was the most beautiful person in the entire school, it did not matter that she was not the oldest, being only in her fifth year, because everyone knew it. She was beautiful.
She had flowing platinum hair, lighter shades flecking into her locks as they were tied together in an immaculate braid which was hanging over her shoulder. The front of her hair somehow staying perfect as it stayed in shape, staying out of her face and flicking in wisps over the top of her head. Never once had Anna seen it fall out of place. Her skin was pale, but not sickeningly so. Her figure was complemented by the Slytherin cardigan she wore which practically clung to her frame, with the help off her school skirt which stopped just before her knees.
There was no denying it, she was beautiful.
Too bad everyone thought that she was evil.
~Ax~
Anna could never forget the first time she met the illusive Elsa Arendelle. It was their first year at Hogwarts, and Anna had just finished saying goodbye to her Mum, Dad and three of the four brothers who would not be attending Hogwarts that year.
She was extremely excited for this year, mostly because she was going to finally learn how to control her magic, the random wandless outbursts had got annoying, but also she could meet new friends and make memories with them.
She was just about to let go of her mum and join Rapunzel on the train when a flash of white caught her attention out of the corner of her eye, she looked towards where it had come from and saw a girl, taller than her, with white hair held back by a blue head band. She looked nervous, but continued to try and get her chest onto the train, with no help from anyone around her, who seemed to ignore this girl.
"Hey, whose that?" she asked her parents and siblings, they all looked to where she was pointing and her mother gasped slightly in shock.
"So it was true, an Arendelle is going to attend Hogwarts this year."
"What's an Arendelle?" Anna asked, still not understanding why her father and brothers all stood gobsmacked with jaws almost brushing the floor.
"They are a family Anna, the closest the wizarding world has to a royal family, they are all pure bloods and very reclusive. No one has heard hide nor hair from the family since the master and mistress of the house, her parents, were killed by a large attack of Death Eaters." He father supplied for her, "She is meant to be incredibly powerful, being born of two pure bloodlines and with parents as powerful as her's were, I am guessing that she will have a lot to give to world."
"Or a lot to take from it," Her oldest brother snarked, "Apparently there is a prophecy about her; it says that either she will save the world from oncoming destruction, or she will be the cause of it."
"Who knows how she will turn out? Her parent's were very powerful, and seeing them be taken down by an army of Death Eaters must be something difficult to forget. No wonder she shut herself off from the world until now."
"She saw them die?"
"Apparently."
"But what's weird is, the Death Eaters were all killed to. After the parents were dead." Her youngest brother, the one attending his seventh year at Hogwarts, added.
"So… she killed them?" Anna asked, frowning as the girl, who was the same age as her, continued to struggle with the bags. Now she noticed that everyone gave her a wide birth, ignoring eye contact and stealing a few nervous glances.
"That's what people say. And so they are all scared of her, because if she could do that at such a tender age, what else could she do now she is older and more matured?"
She didn't even need to look at her father to know that he was scared of her too.
"She looks like she needs help!" Anna suddenly chirped, jumping away when her mum tried to bring her back to them as she skipped over to Elsa, grabbing the end of her case as it started to fall out of the train and pushing with her, Elsa shot her a look of surprise, to which Anna responded with a large smile.
"Come on, push! This thing is heavy!"
Elsa still looked confused but pushed anyway, soon the case was on the train and they both stood back with a sigh of relief.
"Thanks." Elsa suddenly said her voice quick as she spoke.
"You're welcome!" Anna grinned and held out her hand, "I'm Anna, Anna Menzel!"
Elsa took her hand and shook it gently, Anna noted that her hand was slightly colder that she had imagined.
"Elsa Arendelle."
The train's whistle suddenly blew and Anna looked behind her to her family, hoping to say a last goodbye to them.
"I've gotta go say bye to my family, it was nice meeting you Elsa!"
"The pleasure was all mine, Miss Menzel." Elsa smiled a small smile and stepped onto the train.
A few minutes later the train had left the station and Anna was sat in a carriage with Rapunzel and some new friends they had made, a boy with short hair called Flynn who kept looking at her blonde friend and blushing, a fiery red head called Merdia, a shy boy called Hiccup, a broad shouldered boy with blonde shaggy hair called Kristoff who had brought his two friends, Olaf and Sven.
"Hey Anna, who was that girl you were talking to?" Rapunzel asked, heads turned to her and she smiled, remembering her encounter with the girl.
"She said her name was Elsa Arendelle and-"
Flynn suddenly spat out his Pumpkin Juice and started to hit his chest as he coughed. Hiccup patted his back to help him to breathe again.
"D- Did you say Elsa Arendelle?!"
"Yes, what wrong with that?" Anna now frowned, not liking the looks she was receiving.
"She is bad news Anna, have you not heard about what happened seven years ago?"
"Yes, but I don't judge on rumours. She seemed like a nice girl to me."
"She's evil Anna, trust us." Kristoff backed up his new friend, running a hand through his hair.
"Well, we will see whose right at the sorting ceremony then, huh?"
Anna huffed and Rapunzel, seeing her best friend's annoyed scowl, quickly shifted to conversation.
Three hours later
"Elsa Arendelle." The previously loud room, having been filled with cheers when a student had been sorted into Ravenclaw, was now deathly silent. Everyone watched with wide eyes as the girl they had only heard about in stories stepped towards the dirty old hat with a blank expression. There were a few murmurs which were quickly silenced with a glare from Professor McGonagall as Elsa approached the rickety stool and sat down upon it with elegance only a princess could master.
She stared straight through everyone and kept her eyes trained forwards, not moving an inch as the hat spoke to her.
This is it; it would prove if this girl would be a saviour of the world, or the causer of its destruction. It all came down to this.
And then the hat spoke.
And the world came crumbling down.
"Slytherin!"
~Ax~
And now, years later, the hate and animosity towards Elsa Arendelle had increased. Anna had tried to get close to her, but she was persuaded not to by her friends in her first year. It seemed like Elsa was doing fine on her own however, she had taken the tile of the Ice Queen of Hogwarts. A secondary name was given to both herself and her two best friends, Jack Frost and Astrid Ferrera. They were called 'The Unholy Trinity'.
But despite all the hated they received, Elsa especially, none of them seemed bothered by it, rather relishing in the insults and laughing at the muttered comments. Making the best of a bad situation, as her father would say.
"Come on Anna, its time for… ew, Potions." Rapunzel sighed and tugged on Anna's elbow again, breaking her out of her trance. She looked back across the hall and saw that Elsa was now gone. She too, sighed.
Kristoff, Sven, Olaf and Hiccup all called goodbye before going down to their Defence Against the Dark Arts class. Apparently they had arrived at some point too.
They got to their Potions class and sat the row behind the first, arriving seconds before Professor Snape practically glided into the room, flicking his wand at the blackboard and causing the chalk to begin writing a complicated potion onto it.
"I hope you all enjoyed your summer, because now we will be making sure that your minds haven't disappeared in the sunlight." He sneered at the Gryffindors who were sat behind his trinity of prized students, noting how Anna wasn't paying attention to him, choosing to stare at the back of Elsa's head with a dreamy expression.
"Miss Menzel." He said, she did not look up, the other students turned to look at her, and Astrid snorted a little when she saw why she wasn't paying attention. Elsa too turned around, and Anna almost jumped through the ceiling when their eyes made contact again.
"Miss Menzel, I trust you weren't… day dreaming in my class?" he asked, his face blank as he spoke, his words drawn out in that terrifying way he does.
"N-no Professor!"
"Hmm. 10 points from Gryffindor for lying. And 10 more points for day dreaming."
The Gryffindors groaned while most of the Slytherins, minus the Unholy Trinity, laughed at their expense.
"Now, complete this potion in the time given. Be careful, it is highly explosive and if you do not fail to read the instructions carefully then there will be dire consequences. Begin."
Everyone shot out of their seats and got into groups, splitting up to find the right ingredients.
Fifty minutes later and Anna had crushed the red spider like she was told to in the book, squeezing the juice out of it into the potion, counting how many drops she had used very carefully, just like the book had said.
'Add seventeen drops of red spider juice to the Exploding potion, do not use too much or too less, to do so would cause the potion to self destruct and cause horrific damage.'
She was at drop fourteen, when once again her eyes drifted to Elsa.
Fifteen.
She was stirring her perfectly made acid green potion with a small frown of concentration on her forehead. Anna felt her heart speed up when she stuck her tongue out slightly in an adorable manner.
Sixteen.
She brought up her hand to brush a strand of hair out of her eyes, so maybe the hair did break free every once in a while, but it did not change the fact that Elsa was beautiful, not in Anna's eyes that is.
Seventeen.
But seriously, how did she get her hair to stay so perfect? Hell, how was she so perfect?
"Erm, Anna?"
"Wha-?"
Eighteen.
As soon as the drop of red spider's blood touched the surface the potion began to sizzle. Everyone in the room spun around and watched with wide eyes as it started to spark, and then, with a cluttering coughing sound, it exploded.
Anna would have been hit dead on. She would have been flipped through the air and smacked into the stone walls of the potions room. She would have been hit by the acids, her skin would have burnt.
Would have that is, if it suddenly didn't.
It was like an invisible wall, or a dome, had surrounded to cauldron, containing the explosion and taking the hit for the rest of the occupants of the room. The dome was covered in acid green potion, and when the explosion had stopped entirely, the dome disappeared completely, leaving the now used potion to fall to the ground uselessly.
No one dared to speak, still not quite believing that they had all managed to not get harmed by the dangerous potion.
"Heh, nicely done Els." Astrid grinned and leaned back against her desk while facing the explosion scene, using her wand to levitate a part of the useless potion off of the ground and she began shaping it into various objects, ignoring the glares she received for it.
"Is that completely necessary Trid?" Jack asked, smiling none the less.
"Why not? Its fun." Jack stared at her with a blank look, then a small grin came over his face and he levitated his own piece of potion, making it fight with Astrid's.
Anna looked away from the potion, looking to Elsa who was looking at the cauldron with an angry scowl. She looked up, seeing that everyone was distracted partially by Astrid and Jack's battle to notice her, or the fact that she didn't even get out her wand to create the dome.
She locked eyes with Anna and mouthed to her.
'You okay?'
'Yes, thank you.'
Elsa smiled gently at her, quickly using her wand to swipe at Jack and Astrid's battle causing the potion to fly back over to the rest on the floor. They turned to moan at her when she glanced to the door, leaning against the desks, they quickly caught on and copied her, Jack on the left, Astrid on the right.
Snape glided into the room; having left for some reason or another, he took one look at the destroyed potion, the guilty looks from the Gryffindor students who had been working on it, and the smug expressions on Jack and Astrid's face. It was then he knew what had happened.
"20 points to Slytherin for Miss Arendelle's help in saving the classroom. Menzel, Macdonald, Moore and Rider, detention. Tonight. In the Forbidden Forest. The rest of you can go, now."
The class was soon empty.
"That was weird, did Arendelle save us?" Flynn asked, rubbing his head with his left hand, his right currently in Rapunzel's.
"Her name is Elsa." Anna grumbled to herself under her breath, Rapunzel heard her and gave her a sympathetic look.
"Yeah, and look who is having a wee mothers meetin' down there." Merdia added, nodding down the corridor, they all looked and saw Elsa with Jack and Astrid, whispering quickly and harshly while moving her hands about quickly. Jack and Astrid nodded seriously and they soon all left down the corridor, once again with Elsa leading, Jack on her right and Astrid on her left.
"They must be planning something… sneaky Slytherins…" Flynn muttered darkly, Merdia nodded in agreement with Rapunzel reluctantly nodding in agreement.
Anna gritted her teeth together and sped up her walking speed, ignoring her friends as they called after her and getting as far away as she could from them for the time being.
A/N: This was more of a warm up chapter to get myself used to the characters and their interactions, but there were some subtle hints scattered around in here, hopefully you caught onto them :) feedback is welcome, so please leave a review to tell me what you think :)
