I'm so excited to show this story to y'all! This fanfic will focus on the slytherins/death eaters of Harry Potter and my new female character.

There are some changes from canon:

1. The main change is that I have an original female character who is Harry's twin sister, Lillian.

2. Snape never dies. I really love his character I'm not going to kill him!

3. Voldemort never thought Snape was the owner of the wand. He finds out Draco supposedly is. Also, Harry never disarms Draco in Malfoy Manor which means Draco is the true owner.

Also, the fanfic is pretty dark at times. Please don't read if you're uncomfortable about dark topics. I'm writing on Voldemort winning the war so there will be a dark and sad theme to it. There's also romance!

Feel free to comment! I want to know your thoughts. Hope y'all enjoy the story!

Lillian Potter was excited for her first year at Hogwarts school. Her brother, Harry Potter, and her got to go to school for the first time. She remembered clearly that they both were so lucky to get on the train and travel to the school. Their adopted family, the Dursleys, were very nasty and rude to them both. They only cared about their son. Lillian and Harry were unlike them, often seen as quiet or tired of their shenanigans to even express themselves.

Then, the two were frustrated at their family. Harry particularly toward his cousin, and Lillian particularly toward her uncle. Let's just say it didn't end well for either of them that day and the kids got severely punished in return. Later on, they received letters from the owls but as each came in, the next letter was thrown in the fire by their uncle.

Finally, the school got impatient and then thousands upon thousands of letters arrived. The kids eventually got the letter and read it. Mr. Hagrid came along, the large burly guy with a long brown beard unwelcomely arrived at the Dursley's house.

"You are a wizard, Harry." He told Harry and then looked to Lillian. "And you are a witch."

"I'm a what?" She asked in disbelief.

"A witch, Lillian."

She replied. "We can't be a witch and wizard? We are just Harry and Lillian. We are nothing special."

"Well just Lillian. Did you ever make anything happen? Anything you can't explain when your angry or scared?" Hagrid asked.

Harry and Lillian gasped at one another and then looked back at Hagrid, nodding. "Come on, then. We are going to the school! Unless you want to stay of course." Both of them shake their heads no, gather their things, and left.

They got on the train. As they both sat on the train, they meet two others, Hermione Granger and Ron Weasley. "Hello!" Lillian introduced herself along with her twin brother. "My name is Lillian."

"And I'm her big brother, Harry."

Lillian chuckled. "I was born 30 minutes after you. Hardly consider that you are older."

Harry laughed. It was a regular occurrence that they annoyed each other by that little detail.

They finally get to Hogwarts. As they go on the tour they were amazed at the nice scenery. It was strange to both of them. They never seen anything like it. As they waited patiently in the hall, they heard a boy speak. Lillian looked up to see the boy. He had blonde hair, much like hers, icy grey eyes, and skin as pale as hers.

I'm glad there's atleast one person paler than me in this school. She chuckled to herself.

"It's true, then? What they are saying on the train? Lillian and Harry Potter has come to Hogwarts."

There were gasps all around and whispers of the name Harry Potter. "This is Crabbe and Goyle and I'm Malfoy. Draco Malfoy." He announced. There was a slight laugh that came from Ron. "Think my name is funny, do you? Well no need to ask you yours. Red hair and a hand me down robe. You must be a Weasley! You two will soon find out that some wizarding families are better than others, Potter." He explained to Harry, then turned to me. "You don't want to be making friends with the wrong sort." He said, glaring back at Ron. "I can help you two there." Draco placed his hand in front of Harry, hoping he would shake it.

"I think I can tell the wrong sort for myself thanks."

"Harry!" Lillian bumped into him, annoyed how rude he seemed to Draco. "Well I'll be your friend!" She told Draco as she shook his hand excitedly. Draco made a disgusted face at Harry and then looked back at Lillian with a smile.

The class went into the dining hall and was escorted to the front with the hat. It was now time to be sorted in the houses. Hermione was sorted into Gryffindor. Next, Draco stood up as everyone peered at him. Before the hat even reached his head, the hat exclaimed, "Slytherin!"

Ron was sorted into Gryffindor. Next was Harry. As he stood up, there was silence and anticipation among the audience. His time was longer than most because the hat had a hard time deciding which house. It finally exclaimed. "Gryffindor!"

Lillian clapped for her brother as everyone cheered. It was now her turn. She wanted to be in gryffindor so badly because her brother was there. She always stood by her brother's side. She couldn't imagine being split up in a different house. The hat started talking. "You too are difficult. Oh, yes. Caring like your mother, kind, loyal, honest, and hard working, traits of gryffindor. But not as brave as your brother or a gryffindor may be." She huffed with displeasure as he mentioned the statement. "You are very caring like your mother. Hufflepuff suits you. Although, you do have Slytherin qualities, very passionately interested in the dark, mysteriously tragic, and catastrophic side of things. I'll put you in" There was a pause until proclaimed loudly. "Hufflepuff!" Even though she was frustrated with the decision she put on her pretty face and smiled. I wish I was sorted into Gryffindor. She thought. But I guess it was not meant to be.

Lillian went to her first class with her brother who also had Draco as a student. It was Potions class. She came in with the majority of the students already there. "Ms. Potter, come in." Professor Snape told her. Theirs eyes met and she felt his slight uneasiness or shock as he stared back at her. "Sit by Draco over there since that is one of the few seats left."

Lillian nodded. "Yes sir." She made her way toward her seat as she plopped her books in front of her. Draco turned his head to look her way in suspicion and she made a smile. "Hello again." She said to him as he nodded and whispered a hello.

She felt a connection toward him even when they were sitting down beside one another learning about potions. They spoke together a lot after class. She mainly listened to his boasting about how great his father was. Draco was charismatic but she could understand the real meaning behind his charm. She knew he wanted to act all charming but in fact he wanted a true friend to listen to him, to care. Maybe she knew because those years at the Dursleys it was hard. There was only one person she and her brother could confide in, each other. Perhaps he just needed someone.

One day after class he invited her to meet him and his friends for lunch. She ended up having lunch almost every day with him until the rest of the year. Then the next year, and the next. They actually became unlikely friends. Through there up and downs, through the years they managed to still be friends, even through the hard times, even when Draco tried picking on her brother. She had a long talk with him. She threatened to break up their friendship if he wouldn't leave her brother alone. Draco understood and it gave her great happiness to realize their friendship meant more to him than his bully attitude. He stopped making his snarky comments about Harry Potter and his friends.

As the years went on, there was lots of encounters of death that her brother witnessed and potentially almost died himself. She was so frightened of her brother sometimes, especially when the Dark Lord came back. She had heard all about him. Voldemort was the very one who gave Harry his scar. He was the very one that killed their parents. It was stressful knowing he was out there. As the news grew, she became more anxious. Her worried thoughts grew, scared of the danger for the school, her brother, her friends.

Draco and Lillian were in the hallway one day their sixth year, it was their first day back. "Lillian, I want to speak to you."

"What is it, Draco?" She asked him concerned. She knew Draco wasn't acting himself lately. He seemed deeply troubled, much like herself.

Draco looked around to make sure no one else was in the hall enough to see them. He was going to speak, but he couldn't find the right words to say. Instead, he quickly pulled up his sleeve to show Linnetta his new tattoo. The dark mark. Lillian raised her hand to her mouth as her eyes watered. "Draco." Her voice broke. "You can't- you're one of them?" She asked in disbelief.

"Please, I wanted to tell someone- anyone."

"For what, Draco?"

"I-"

"I can't believe you!" Tears streamed down. "I never knew you would turn into a death eater!"

"Lillian, please. I don't want this and I don't know how-"

"You can't go through with this! I can't be friends with you anymore, Draco." Tears fell from her cheeks. "I'm sorry." She left him, tears flowing down her face as sadness overwhelmed her.
