To my usual readers it's probably a surprise that this story isn't going to be one for Avatar: the Last Airbender since up until this point that has been my primary fandom. But recently, I've found myself becoming immersed with the Harry Potter world especially after I watched the series on TV. Hogwarts Mystery has only added more to my fascination, and since I've been wanting to write some Harry Potter for ages, I figured why not start with my own version of the game?

This story will take place before the Harry Potter series kicks off, since it will focus entirely on the events that occur throughout the game. It will primarily focus on my OC, Abby (who I named after myself for the fun of it) as she goes through her Hogwarts experience. There will be certain events added into the story just to add some more drama to it for my liking, so it won't follow the game through and through.

As for the story itself, it will be split across seven separate stories, one for each year. I'm not sure how long this first story will be but it should be roughly around 20 or so chapters long. It's worth mentioning that I am not claiming any ownership of the main events for the story, as they belong to J.K. Rowling and the creators of the game. This first chapter is more like a prologue that sets up some of the other stuff that I have planned. Anyways, I hope you guys enjoy reading the first year of Mysteries of Hogwarts as much as I enjoy writing it :).

Note: This first chapter has been edited and is no longer the same as the original post.

Left Behind

As she creeped up the stairs, nine-year-old Abby Selwyn did her best to remain quiet. She knew what the potential consequences were if she got caught sneaking around when she was supposed to be locked up in her room, but Abby didn't care. What Abby did care about was getting to see her brother. She hadn't seen Jacob since he got home, and although her father was doing his best to keep her in the dark, Abby knew that Jacob was in trouble. There had been whispers about what he was getting up to at Hogwarts, and none of it sounded good.

When Abby heard footsteps from beside her, she made an effort to stay hidden as she saw her father angrily walking ahead. Abby didn't need to look at her father's face to know that he was undoubtedly furious, and she knew that Jacob would be on the other end of that fury. The rage of Rogelius Selwyn was not something to be underestimated, that was for sure. Abby continued following her father until he entered his office and yanked the doors open, which Abby stopped from closing just so that she could peak through to see her brother.

Because Jacob's back was to her, Abby couldn't see his face. His shoulders were slumped though and Abby didn't even need to see his face to know how her brother was feeling. Their father was surely about to make him feel worse, a fine talent of Rogelius Selwyn. Her father was the epitome of a pureblood supremacist, that much was clear to Abby. Despite his best efforts to make her and Jacob into one of him, his actions only made his two children resent him for what he had done to their family. Abby longed for the days when it was just her, Jacob and their mother at the Manor, back when their father had been imprisoned for his war crimes. Ever since he had come back, their family just wasn't how it had been in his absence and Abby much preferred those times. She might've been young then, but she was young enough to understand that her father wasn't what he should be, that much was clear.

To the public eye, the Selwyn family was the epitome of your perfect pure-blood family. That was the furthest thing from the truth behind closed doors. The family patriarch, Rogelius Selwyn, was a pure-blood supremacist who openly supported Lord Voldemort in the first wizarding war, only getting away with three years in prison prior to his downfall. In the time that her father was in prison, Abby had seen Jacob happier than he had ever been. They had more fun together and were actually allowed to be together. Their family was just so much better without their father. But then her father was released and their family became like it once was again, and Abby could see how sad it made her mother. Then her mother was dead and it was just her and Jacob with nobody to really look after them. This was during Jacob's first year at Hogwarts and Abby could still remember the devastation on her brothers face when he came home only to learn that his mother was dead.

After that, Abby could see how her brother changed. She knew that Jacob wasn't telling her everything, but she could tell that losing their mother made him sad. It hurt her to see him in pain and she wished that their mother was still here to protect them from their father. At least with her around they stood a chance and were safe. Safe from their fathers wrath which Jacob was clearly about to get.

"I received a letter from the Ministry. They want you to stand trial next week," Rogelius yelled. "Not only that, your face is now plastered all over Daily Prophet."

Abby's eyes widened. Trial? For what? Of course she knew that her brother was in trouble but she hadn't thought that it was that serious. Jacob shoved the paper away that their father had thrown at him. The rage in her father's face was undeniable and Abby found herself fearing for her brother. The rage of Rogelius Selwyn was not something to underestimate.

"Everything I did to restore our family's good name thrown to trash because of your irresponsible actions! What were you thinking, you idiot?" Rogelius roared.

"I needed to find the Cursed Vaults," Jacob simply replied.

Rogelius glared at him, "Those were of no concern to you! I told you to leave them alone! Why don't you ever listen to me, you insolent child?"

"Why should I listen to someone who commands respect but never gives it in return?" Jacob remarked.

Abby grinned to herself, loving it whenever Jacob gave their father attitude. Then she started to worry again, knowing how much her father hated getting attitude from anyone.

"How dare you speak to me like that! I am your father and you should treat me as such!" Rogelius yelled.

Jacob scoffed, "That's ironic coming from you, considering you have a daughter but you hardly treat her like she is yours."

"That little brat is nothing but nuisance! All she has done is bring our family down. She is the reason your mother killed herself," Rogelius seethed.

Hearing her father talk about her like that definitely wasn't easy for Abby to hear, but it's not like those words were anything new. Her father had never treated her half as good as he treated Jacob, and that was saying something since he barely treated her brother nicely. Abby knew that her father blamed her for her mother's death, something that she could never understand since she failed to see how it was her fault. Her mother had been so much happier when it was just them three, but then her father returned and she became sad again.

"That is not true and you know it, father. Mother killed herself because you had stopped treating her with love. You barely even looked at her like she was your wife. What you did destroyed her," Jacob said, though Abby didn't quite know what her brother was referring to.

"What I did was a mistake that never should've happened. Ever since then my life has been a crumpled mess as I've been trying to fix one after another to keep our family name intact," Rogelius said.

"Am I supposed to feel sympathy for you, father? Because I don't," Jacob snapped as he got to his feet. "Everything that has happened to you has been your fault. You were the one who devoted yourself to that bald snake man and got yourself thrown into prison. You were the one who made the mistake that caused your wife to take her own life. That was all you, father."

It was no secret to Abby that her father supported He-Who-Must-Not-Be-Named. That was the whole reason why their father had gone to prison in the first place, and Abby only wished that he had been there longer.

"Clearly I didn't raise you with enough respect because that is not the way to talk about the great Dark Lord," Rogelius shook his head in disapproval. "You have brought more shame than ever to our family name."

"Your great 'Dark Lord' is hardly a person worthy of supporting considering he was defeated by a child who was barely a few months old," Jacob remarked.

"I will not have a son like you soiling our family more than it already has been! Your actions leave me with very little options" Rogelius sneered.

"Then I guess I'll make this easy for you," Jacob stated as he turned to leave his father's office. "Goodbye, father."

"No. Jacobus Horatio Selwyn, you get back here right now!" Rogelius demanded.

"No, father. I'm not taking any more orders from you," Jacob asserted himself. "I'm not going to sit here and let you treat me this way anymore. If it was an option, I'd take Abby with me but I unfortunately cannot do that. I hope she doesn't have to suffer at your hands any more than she already has."

What? He was going to leave her? Of course Abby knew how much her brother hated their father and would rather be anywhere else than here but she never thought that Jacob would abandon her. He said he wouldn't. He promised.

Just as Jacob could reach the door, Abby's breath hitched as she saw her father yank his wand out from his pocket and called out the Cruciatus Curse towards her brother. Unable to defend himself without his wand, Jacob writhed on the floor in pain as the curse came into contact with his torso. There was nothing more that Abby wanted to do than to step in and protect her brother like he protected her, but she had promised Jacob that she would never let herself get hurt over him. She might not respect her father enough to listen to him, but she respected her brother more.

What upset Abby more was that she knew this wasn't the first time that their father had hurt Jacob. Their father was never a nice man, and although he hadn't used his wand on Abby yet, she feared for the time when he would snap and do to her what he was doing to Jacob. Abby let out a sigh of relief as Jacob got to his feet and managed to slip through the door of their father's office. When he did, Jacob was momentarily stunned to see Abby standing there before him.

"Father hurt you, didn't he?" Abby asked timidly.

"Yes, he did," Jacob replied, since there was no point in lying to Abby when this could quite possibly be the last time he spoke to his little sister. "Come with me, Abs."

Following her brother, Jacob lead his sister to their favourite hiding place at Selwyn Manor that their father knew nothing about. It was just lucky fortune that they had stumbled across this place during one of their many explorations a few years ago. Now it had become a place for them to hide together in peace, away from their cruel father.

"I'm just letting you know that I have to go," Jacob said as he clasped his sisters hands tightly.

"Why do you have to leave?" Abby asked, tears beginning to fall down her face which Jacob wiped away with his hand.

"I'm not wanted here anymore. I can't stay in a place where I'll be shunned," Jacob replied.

"But I want you. I don't shun you," Abby insisted.

Jacob sighed, "Don't make this harder than it needs to be, Abs. I don't like this as much as you do but father has made it clear that he doesn't want me here. He only wants me around to keep up our family pretence. But now I don't care about keeping father happy anymore when he doesn't care about my happiness."

"But what about me?" Abby's lip quivered.

"I don't like leaving you alone with that man but this is something that I have to do. Please understand," Jacob pleaded with her.

"I don't want to but I think I do," Abby whispered sadly.

"If you ever miss me, little sister, just come here and remember the good times we had with mother," Jacob said as he pulled her in for a hug.

"I'll miss you," Abby cried.

"I'm already missing you. But we'll see each other again one day when the time is right. Just be strong, little sister," Jacob whispered.

"I'll try. But I don't think I'll be as strong as you," Abby murmured.

"You already are for what you have had to endure," Jacob smiled sadly down at her, holding her face in his hands before leaning down to kiss her forehead.

"Where will you go?" Abby asked.

"Somewhere I can be free. Somewhere I can be myself without worrying about pure-blood supremacy. Maybe one day you can come find me and we can be together again," Jacob reassured her before pulling something out from his pocket. "I wanted to give you this before I left."

"Your family ring," Abby gasped upon recognising the family heirloom.

"Yes, my family ring that is now yours. I want you to have it because no matter what father says, you are still family," Jacob said as he put the ring in his sisters hands.

"I'll wear it every day," Abby promised.

"Just keep it away from father. He might take it away from you if he finds out that you have it and I don't want him to do that," Jacob told her.

Abby nodded, "Father will never know."

"It'll be our little secret, just like this place," Jacob murmured as he gave her another hug, dreading the thought of saying goodbye to her.

"Don't forget me," Abby said.

"Like I could even try," Jacob remarked.

"I'll miss you, big brother," Abby cried.

"I'll miss you too, little sis. We'll be together again one day, I promise," Jacob whispered.

"I hope we are," Abby murmured.

With that, Jacob gave her one last kiss on the forehead before disappearing from the room and out of Abby's life for what she feared would be forever. Without Jacob around, Abby was scared to be alone with her father. He had never exactly been the fatherly type towards her or treated her the way she thought a father was supposed to treat his daughter. Now that Jacob was gone, Abby feared more than ever for what her father would do to her.

All Abby could do was hope that like Jacob had promised, they would soon one day be reunited so that they could be together again. Perhaps Jacob leaving would be the pull that their father needed to start being more of the family man that he should be. Or maybe it would only make things worse for her and she'd be left wishing that Jacob had taken her with him. Despite her age at only nine-years-old, Abby knew that she would eventually find out the consequences of these actions and just hoped that they wouldn't be too bad.

And that's the beginning of a seven story arc that will definitely be worth the read. Trust me when I say that you guys are going to enjoy what I have planned for this series. On another note, what point are you guys up to in Hogwarts Mystery? I'm currently waiting on Chapter Ten of Year Five. In saying that, feel free to leave me your thoughts on the beginning and any suggestions you might have for improvement or ideas.
