A/N This is my first fanfiction. English is not my first language. I do not own Harry Potter, Once upon a time or Downton Abbey. They would probably not so successful if I did. Rights belong to their respective creators. That counts for the song as well. This is complete AU and OoC.

Chapter 1: Compartment 27

Hermione was very excited. It was her first day at her new school. A few weeks prior she found out she was a witch and she would be able to attend one of if not the best wizarding school in history, Hogwarts. To get there, the young girl had to ride a train and being totally excited and paranoid she was nearly an hour early at platform 9 ¾. After saying her goodbyes to her non-magical parents, she boarded the train and went into the last compartment possible. She was rather nervous meeting new people and hoped a little that she would not be bothered by anyone before the Hogwarts Express arrived at its destination. Realising she had a great amount of time, she unpacked the book „Hogwarts: A history" and reread it. After getting her things in Diagon Alley, it soon became her favourite book. She wanted to be prepared for her new school.

Mary strutted around the train. After being left at the station with her sisters by her driver, she walked away from Edith as soon as possible. „Like anyone wants to spend time with their siblings. Stupid Edith, and Sybil is far too young, I am glad I can finally be alone" she thought while looking for a compartment. She loved it at home or at least the parts where she was spoiled rotten by her parents and her servants. Her parent nearly worshipped everything she did but Edith hated the attention she gained and only made snide remarks about her. Lost in her thoughts she bumped into a redhead „Watch where you're going, moron! Oh it's you, Z" Mary greeted her friend. Zelena rolled her eyes and gave her a half- hearted shrug as a greeting. „So glad to be back and see you too, Mary." „How was your summer?" "I am delighted to be back, finally allowed to use magic again. I stole a book about Dark Arts from my mother and can't wait to use them on some idiot munchkins and elves." „Still not over that it seems." „I just want a little revenge, that's all." „Whatever you say. How are all the compartments full with peasants and or Gryffindors?" Zelena shook her head with a grimace on her face." That one has only one girl in it." „But she seems as young as my sister and she reads. I hate such people." „You read too, you know." „But not Hogwarts: A History, Z." „But we can intimidate her, so she won't be annoying us. I really don't want to stand anymore." „Stop whining. But you have a point. Let's go in." As they walked in they both gave the girl a death glare which caused the young girl to shrug and she kept on reading.

Crabbe stood outside Honeyduke's Express at Platform 9 ¾. He was so hungry that he could not wait until the trolley came during the ride. After buying about 15 choclotae frogs and 20 pumpkin pastries, he got on the wagon beside the shop. Being lazy, he chose the first compartment he saw. There were already three girls seated, one of them his age, the other two who talked to each other quietly definitely older. Without saying anything, he dropped off his food and took the seat besides his food facing the window. „You are rather rude not introducing yourself." The girl, actually young women, with the long black hair scolded him. As the redhead chuckled and rolled her eyes, the girl spoke up"You are a hypocrat." „ I beg your pardon?" The teenager sneered while her friend was laughing rather manical. „ You did not introduce yourself either earlier." The young girl answered. „ You have got some nerve. I am the eldest, therefore you two should show some respect. I do not talk to people beneath me." „As I said, hypocrat." Crabbe began eating a pumpkin pastry, profoundly disinterested in the conservation. After the redhead finished laughing at her friend, she said"I am Zelena Mills and she is Lady Mary Crawley." Crabbe recognized the names but couldn't really place them but then he did not actually care and mumbled " Vincent Crabbe." The young girl introduced herself as Hermione Granger. „So now that you know our names, please shut up, so we can resume our enlightening conversation. If you do disturb us, Z might hex you. Even though she thouroughly enjoys that, I as a prefect have a duty to keep you freshlings at least a small amount of safe." Hermione rolled her eyes and Crabbe just looked at them mouth hanging open, so the rest of his pumpkin pastry was visible. „Would you mind shutting your mouth so I do not have to see the rest of your breakfast? Because this might just be the most disgusting thing I have ever laid my eyes on." Mary barked at him. He only shrugged and looked out the window, the train finally moving.

Severus was supposed to guard the train for the first hour as prefect. But to him this was just a nuisance and as he roamed the wagons he actually didn't bother to look for abysmal behaviour. He disliked people a lot so he was not going to talk to most of them. It was the first day to use magic again in three months. Needless to say that a lot of smaller fights were going on. He saw the Weasley Twins shooting filibusters in the direction of Daisy, an annoying Hufflepuff Second year. She probably just asked what they were and the Weasleys wanting to show her. Later the Slytherin watched a blonde kid who looked like he was a mini Lucius Malfoy throw a toad out the window. Then he heard a voice" I'm gonna show him who doesn't have the nerve." Facing ahead again, Severus watched O' Brien, a 3rd Year Slytherin muttering angrily to herself. „O' Brien! What are you doing?" The prefect asked actually rather curious. O' Brien usually showed up together with Barrow. These two were as thick as thieves. „Barrow dared me punishing the Queen for her mother laying off needless staff." „So the Crawleys laid off staff, so what?" „I need the job for the money, I don't have family that's how I pay for my school supplies." „Actually, I can't see how the almighty Crawleys are able to live without their slaves." „First of all, I was a servant and second of all they are not. They inherited some house elves. And these highpitching dwarves stole my job. Seriously like they were great company. Hows are doing mylady. It's lovelys to subdues to every of your orders! Urgh, I hate them." She ranted. „Any company is better than yours" Snape muttered under his breath. „So what are you planning to do to our Slytherin Lady?" „I want to turn her into a toad. You know, where she is?" „Haven't seen her yet but I'll help you find her." „Are you sick, you helping someone?" „Well, her best friend the wicked witch is probably with her and she will hex you into oblivion, I do not want to miss that." He answered. O'Brien huffed and they walked together. After a few minutes they finnaly found the right compartment. O'Brien marched into the compartment, wand drawn while Severus was walking behind her, grinning widely.

All heads went to the loud intruder. „What do you two want?" Mary asked harshly. „I merely want to enjoy the show." Severus answered, receiving confused looks. „You and your blasted mother are the reason my life sucks!" O'Brien spat. "How does your life concern me?" Mary asked. " Well for starters, it's your bloody family that thinks that everyone around them is no better than dirt." " May I silent her, please?" Zelena whispered to Mary who gave her a curious look. The redhead took that as approval, whipped out her wand and shouted"Ossa resurgite!" There was a blinding flash and smoke everywhere. The force of the spell pushed everyone backwards a little. Some luggage was spread on the floor, a few books stranded besides Severus, missing him by inches. "What did you do?" Hermione asked in a mixture of annoyance and condescendence. Mary whined "I've got food all over me. My clothes are effectively ruined." "Lucky you. I can't eat my food anymore 'cause it's all over you!" Crabbe hissed disappointed. "Zelena, what spell did you just use?" Severus asked, already regretting coming together with O'Brien. "I don't know, I found in one of my mother's books, it didn't say what the spell does." "You used a spell without knowing what it should do. And one you found in the books of the Queen of Hearts" Snape stated calmly." Do you ever use that brain of yours?" O'Brien shouted. "What? I can't have done anything too bad, right?" "I don't want to interrupt you two, but who is the Queen of hearts?" Hermione asked timidly. Snape said" During the war she apparently took out hearts out of people's bodies and crushed them right in front of their families. That's her mother." The young girl widened her eyes and looked at Zelena. "That is not true, my mother did not take out hearts." Zelena spat. "That does not matter right now, what matters is what your spell did." Mary interjected."The smell of peasants and first years is really giving me a headache." "Then, let me make it easier for you my royal pain in the back! I am leaving!" O'Brien spat out and marched out the compartment. "Wow, she has a rather short temper." Hermione commented. "Who are you? And you?" Severus asked eying Hermione and Crabbe who still watched the food on Mary jealously. "I'm Hermione Granger and that is Vincent Crabbe. Both first years." Then they heard some shuffling and an earpiercing scream. "What was that?" Zelena asked. Suddenly, the compartment door burst open once again revealing O'Brien, white as a sheet. "The question should have been: Who was that." Mary commented." What happened?" Severus asked. "You know the spell that wicked witch used? Somehow she must have turned the rest of the train into undead people and one of them attacked me in the wagon." O'Brien shrieked. "There are Zombies on the train!?" Hermione half-asked, half-shouted. "She was merely joking. There are no such thing as undead people." Severus said. "Seriously?! Why would I make that up?" O'Brien started but was interrupted by someone screeching on the corridor. Snape turned around and looked at a slimy person whose tongue stuck out. Her arms motioned and banged on the compartment door. Severus jumped back a little while Hermione was screaming. Crabbe's mouth hang open and O' Brien looked rather smug. Zelena mused over the similarities between the "person" outside the compartment door and the fat first year. The Zombie kept banging the door until the glass started cracking. Then Mary finally used her head, took out her wand and shouted "Petrificus Totalus". That sent the person flying back and it lay on the floor. "Well, you might have been right." Snape commented." That means we have a problem." "I can turn people into zombies." Zelena stated proudly and her face split into a crazy grin. "Do any of you recognize the girl?" Mary asked. That caused everyone to shake their heads. "But she looks rather old to be a student." Hermione commented. "Are you sure?" O'Brien asked. "Well she rather looks thirty than 19." Hermione stated. "Maybe she works on the train." Crabbe mused. Rolling her eyes Mary said" The only people working here are the old lady pushing the trolley and the driver. Everyone knows that!" "It's my first time riding this train. How am I supposed to know that?" Crabbe answered. " Well if that person is not actually meant to be here, that means" Snape started only to be interrupted by Zelena rather happily "That means I can conjure zombies. Wow." "Or you sent us to another place where there are zombies. And stop grinning. They are ready to kill us. Do you want to die?" Snape finished. "Relax. We will find the counter curse in one of my mom's books and then it will be over." "Then let's start looking." Hermione stated eagerly. Everyone eyed her suspiciously. "What? I love reading and researching. It's exciting." Zelena rolled her eyes and opened her trunk. "This is the book." She said grabbing a black-coloured small book which seemed rather worn out. Mary snapped it out of her head, while Hermione took out an MP3- Player and turned it up to full volume. The other's looked at her strangely, while it blasted through the compartment:

Wenn Du denkst, Du bist hässlich

Und keiner mag Dich wirklich;

Wenn Du denkst, Du bist dumm

Und deine Freunde hacken nur auf Dir rum;

Wenn Du denkst, es geht nicht mehr,

Kommt von irgendwo ein Fresh Dumbledore her!

Wenn Du denkst, Du bist allein,

Denk an mich und denk an diesen Reim.

"What is that?" O'Brien asked. "The song is by Fresh D. He is a rapper, he is a little underestimated. I always listen to it while doing research. It puts me at ease." Hermione answered. "Great, a mudblood." Mary sighed. "Not everyone can be as sacred as you, my lady." O'Brien muttered. "You understand that language?" Severus inquired "No, that's why it puts me at ease. I don't analyze the song." "Can you turn off that noise? It makes my ears bleed. And has anyone any food?" Crabbe commented. As Hermione moved to turn off her devise, Zelena shouted "Destructo!" which destroyed the MP3-Player. Hermione shot her a death glare and asked annoyed" What did you do that for?" "Well, he asked. And that's a muggle devise. It needs to be destroyed. I merely helped." Then, Zelena felt a sting on her cheek and fell to the floor. Hermione towered over her with a telescope which she took out of Zelena's trunk. O'Brien chuckled while Severus was enjoying this new development. Zelena recovered rather quickly and shouted "Oh you wish you'd never been born, you filthy little" "I found it! I found the spell!" Mary interrupted. Everyone turned to her, although Zelena kept one eye on the young girl. "Then reverse it." Severus urged. "Well I found the spell she used. It says here: The spell brings the room in an alternate universe where Zombies try to kill you." "Well, your grace, we already knew that." O'Brien barked. "Let me finish, you rat. The only way to break the spell is to find clues and be in the right place at the right time. Try not to get killed." "Thanks, Zelena. I always wanted to die by Zombies eating me." Severus commented. "This can't be right, Mary." The redhead said. "Then, look for yourself!" Mary shot back. "Oh great, that's what I get for taking a dare from Barrow." O'Brien growled. Zelena reread what Mary quoted and let out a frustrated huff. "What do we do know?" "We? You brought us into this mess, you get us out of it!" O'Brien said. "As much as I'd like for Zelena to be trampled and eaten by zombies, I do not trust her to break the spell." Severus injected. "Do you insinuate, I am stupid?" Zelena shrieked. "I wasn't the one who used a spell from a book without knowing what it actually does." "Well, let's start searching the train. It sounds like there's a time limit until the spell can be broken. The sooner we are out of this nightmare." Mary commented. "This sounds like a computer game I never wanted to play." Hermione sighed. "In this book of yours is there anything about food in this alternate universe?" Crabbe asked hopefully.

A/N: I wrote this because I talked with a friend of mine and she said she wanted to read one of my fanfictions. I apologize to everyone else who endured this. I probably won't update this as I am lazy as hell, although I should write my college essays and as I won't be doing that any time soon, I actually might update this. I'd like some reviews, I probably answer them because I would find it funny if anyone wants to comment this. To my friend: That is what you are envious of? Are you mad? And I am still laughing at that( You will understand that during my next letter, I promise). Anything in this story is weird and not explainable. For anyone who hasn't understood that yet, this fanfiction is complete AU and a weird crossover between Harry Potter, OUAT and Downton Abbey and some computer games with zombies that I've played way too much in the past months. Every Character is probably out of Character and the ages are nearly all messed up. On top of that, I can't tell you if there are spoilers in this because I don't even know what on earth I was writing. I wrote a Zombie AU, even though I don't even read those because I think they are weird. By the way, I had no beta on this and I haven't reread it myself. Again I am sorry, although I have read some fanfiction that was not better than this. Maybe a bit more story because I am allergic to story. In anything I write you could realise that story is a foreign word to me and that I actually suck or as I prefer to say I have my very own unique style that no one but me gets. Well, or I just suck. I let you decide. And this is for my friend: If you think it doesn'T go anymore, there will be a Fresh Dumbledore somewhere.
