A/N: So the first few chapters will mostly be an introduction to Cassandra and other OC's hence why they might be shorter (and thus boring) than the rest of the fanfiction, bear with me, I need to explain all the intricate details and why some things happened they way they did due to her early childhood.

P.S. Thank you so much for choosing to read my story it means a lot to me! 3

Chapter 2

Cassandra sat next to Regulus, smiling at her new classmates and introducing herself to other first year students. She remembered the girl from their boat ride who remained quiet and unbothered by the possible squid attack.

The young witch learnt that her name was Lisa, and Lisa seemed generally interested in their conversation.

Regulus Black on the other hand was chatting up a boy who looked like he had just survived the holocaust, with his long greasy hair falling over his face and ghastly appearance, Cassandra could have easily mistaken him for a ghost. After a few more attempts to interest the boy Regulus gave up and turned back to Cassandra who was fervently listening to Lisa's explanation of the muggle world. Her mother was a muggle-born witch and her father was a half-blood wizard. They had assured Lisa she wouldn't end up in Slytherin so the young girl was now worried her parents might be disappointed to learn of her house.

"It doesn't matter though…" Cassandra started to explain but was interrupted by the headmaster who had just gotten up to hold a speech. She was shushed down by the Slytherin prefect turning around to listen to the speech Prof. Dumbledore was giving.

After the rather long and boring speech, he gestured towards the tables that suddenly filled up with food Cassandra could only dream about. Sure her parents were able to afford a house and average food, but a feast, during such time, was rather rare.

She dived in and joined the dazed Lisa in eating a Shepherd pie, filling herself a glass of pumpkin juice.

Having finished the main course, they were surprised by the sudden change of the dishes in front of them, to all sorts of assorted desserts. Opting for a lighter meal, Cassandra took a handful of grapes and slowly ate them as her new friends gulped down other sorts of desserts.

Finally with full bellies they sat back and almost fell asleep. That is when their prefects got up and signaled for all the first years to follow them. With heavy legs and eyelids, the girls got up and followed the older prefect, while Regulus followed in suit. He seemed to have gone to talk to his brother, and the conversation didn't seem to have gone that well.

"I can't wait for tomorrow's classes!" Cassandra suddenly exclaimed wanting to switch the subject to something else. "I saw that our first class is potions!"

But neither of the other two kids showed such enthusiasm. Lisa was nodding, half-asleep, barely catching up with the rest, and Regulus just wasn't paying her much attention. Defeated Cassandra quieted down for the rest of their journey to the dungeons and the Slytherin common room.

Once there, she gasped at the underwater ambient, a wide window peering in to the black lake.

"Girl rooms to the left, boys to the right." The prefect sighed before leaving the common room. As the first years scuttled around the common room slowly filled up with other students from other years. Most of them didn't pay much attention to the children and hurried along with their business. Cassandra and Lisa decided to head for their bedroom, and meet other girls that would be sharing the bedroom with them.

Upon entry, they immediately noticed a tall red haired girl who was arguing with a smaller, petite brunette girl over the fact whose bed is whose. They both jumped up at the sound of the two girls entering, and seeing as they weren't professors continued bickering.

"Uh, I'm gonna take this bed then…" Cassandra pointed to the furthest one away and Lisa giggled sitting on the one next to to the door. Finally the the red haired girl gave up, took her stuff and sat on the bed next to Lisa, quite begrudgingly leaving the other girl to gleefully take her spot next to Cassandra.

"I'm Amy…" She smiled inquisitively to Cassandra. "Pureblood, what about you?"

"Uhh, I'm Cassandra, and I'm a half-blood I think, dad's a pureblood, but mum's a half-blood…" The girl answered, not entirely sure why Amy had to ask her that.

"Well that makes you more of a pureblood than half so it's fine, what about you, rosy face?" Amy looked at Lisa, but the moment Lisa explained her mother's blood status the girl's face contorted in to a grimace. "Great, there are now two mudblood lovers in my dorm."

"Mudblood?" Cassandra stared at her until the red haired girl answered.

"It means of filthy blood, she's saying that just because one of our parents is muggle born, we're of filthy blood as well." Red haired girl glared at Amy who just shrugged it off, mumbling to herself how she wasn't wrong.

"And what's your name?" Lisa turned to her bed neighbour.

"Rosemary, you can call me Rose though, or Mary…" Shrugging off she started undressing her uniform and putting on her pajamas.

"Well, my mom calls me Cass, or Cassie so if you want you can call me that, or Sandra, Sandra is cool too…" Cassandra's voice trailed off as she got in to her pajamas and lied down on to her bed, falling asleep within seconds of her face touching the pillow.
