Wish Upon a Star
Chapter XI

The days of September quickly went by. Theia continued to adjust to her new life. If she wasn't the top student of her year, then she was close. She knew the material, she completed her homework, and she assisted others.

Theia knew she owned Hermione something special. Her friend had taught her to do her best in class and to get her homework done in a timely manner. It took Hermione awhile to break Theia's old habits. The Dursleys won't have her doing better than their son, and if she did then there was hell to pay.

Theia found she liked most of her classes. Defense Against the Dark Arts was still her specialty, and one of her favorite classes. Professor O'Riley knew his subject, and he was passionate about it. While Theia hadn't had Professor O'Riley before, she could tell there was a difference in the learning with one continuous professor. Professor O'Riley started the year off with a review before moving onto new material.

Ancient Runes and Arithmancy were amazing classes. Theia was kicking herself for never taking them before. She shared both classes with Aries, and Aries was amazing to watch. Theia knew the future career Aries had ahead of her, and her passion and skill were clear at sixteen.

Charms wasn't the same without Professor Flitwick, but Professor Addams knew her subject and she was a good instructor. Speaking of Flitwick, Theia wanted to look him up. If she remembered correctly, he was quite the duelist in his youth.

Potions was a different experience with Professor Snape breathing down her neck. It appeared that Theia was decent at Potions. While she found the subject more enjoyable, Theia still hated her professor. Professor Slughorn didn't even try to conceal his favoritism. He even went as far as to award points for "correctly cutting" or "lending a helping hand" to his favorite students, all of whom were members of The Slug Club. If another student did the same actions, the student was ignored.

Theia wasn't sure what to think of Transfigurations with Professor Dumbledore. It was different. Professor Dumbledore was a good professor, but he was bias towards his own house, Gryffindor. Professor Dumbledore wasn't as bad as Professor Snape, but it was obvious.

Magical Studies was an interesting class. Professor Caldwell knew her subject, and she had plenty of information to teach each class. For the most part, Theia knew a good amount of the information from studying the Black library and lessons with Melania over the summer.

Theia took notes on each class with the pros and cons on the professor, and she sent her reviews to Arcturus. There were areas the he and the Board could improve on: such as notifying parents or guardians when a student received detention with who and why; and posting a list of points each student gain and loss, and the reason.

...

There were mixed reviews amongst the Slytherins concerning the Muggle Studies class. Theia didn't know what most of the Slytherins thought, unless they shared their opinions in the middle of the common room like Walburga Black.

Ever the pure-blood supremest, Walburga thought the class was a waste of time and the subject was useless. She was one of several Slytherins skipping the class. Her attendance record would be reflected in her grades.

Grading was another change Arcturus was bringing. The grading system would remain the same with Troll through Outstanding. A grade would now incorporate more than homework and tests. It would now include attendance and class participation. Passing a class would require more than studying and decent homework.

From amongst her group of friends, the Muggle Studies class was something of hit. The pure-bloods and magical-raised were stunned at the advancements of the muggle world. There was a wireless radio system and horseless carriages called automobiles. The advancements were mind-blowing.

Virgo, Aries, and Libra asked Theia numerous questions about everything ranging from pens to automobiles to major muggle cities. Theia answered the questions to the best of her abilities, but she didn't know much about major muggle cities in this time period. Most major European countries were gearing up for the Second World War. If Theia remembered correctly, it would start soon – if it hadn't already.

In addition to magazines, Theia would need Izzi to pick up some muggle newspapers.

...

September turned into October with rainy days and colder temperatures. Theia adjust to life in Slytherin. She was doing well in classes, and she making friends. Having more than two close friends was surreal to her.

Growing up, Theia didn't have any friends. Dudley and his gang scared everyone away from her while Petunia and Vernon warned off parents. When she got to Hogwarts, she had Ron Weasley and Hermione Granger. While there were other people, like Ginny Weasley and Neville Longbottom, that were amongst her friends, her closest were Ron and Hermione.

Now, Theia had Orion and Lucretia. She was closest to both them with Orion being her betrothed and Lucretia being like her little sister. Lucretia and Theia shared numerous secrets between them. Most of their secrets were about their relationships and their opinions on somethings. For example, Lucretia was debating what to give Ignatius Prewett for their one year anniversary.

In addition, Theia had Aries, Libra, and Virgo. Out of the three cousins, Theia was closest to Aries Nott. They were close enough friends that Theia knew Aries considered herself more of a Black than a Nott, and she wanted to marry into the Black family. This was a feeling shared by Libra Rosier. Knowing this, Theia was trying to think of someone for each girl to be betrothed to. Theia thought Alphard Black might be a good choice for Aries. She just needed to figure out a way to broach the subject with Alphard, Aries, and Arcturus.

Theia wanted Alphard to have a good future. She remembered he never married or bonded, and he was Sirius' one of favorite relatives. Aries, also, deserved a better future.

...

When Samhain came, Theia attended classes before retreating to her dorm room. The Slytherin dorms were warded against entry from other students. If it wasn't their dorm, then they couldn't enter. The wards gave Theia peace of mind. She knew Walburga couldn't enter her room and go through her belongings.

In her dorm room, Theia changed out of her uniform and into a set of casual dark blue robes. Wanting to keep her mind off of the day, Theia pulled out some of her copied books. There was no better time to start her research into the Black family looking for a Parselmouth. There was so much to learn.

Theia didn't know how much time passed before her roommates returned. A look of relief passed over Virgo's face when she saw Theia seated on her bed.

"There you are," Virgo said. "Orion and Lucretia are looking for you." She dropped her bag on her bed and turned to look at Theia.

"Are you alright?" Libra asked, staring at her friend.

"I'm be fine tomorrow," Theia answered. "I don't like Samhain."

The three cousins shared a look. None of them knew the reason. Hopefully Orion or Lucretia knew.

"Orion wants to talk to you," Aries said.

Theia glanced up from her book. She nodded, marking the page. Without another word, Theia got up from her bed and she headed to the common room.

Orion was seated in the common room with Edward and Anthony next to him. When she stepped into the common room, Theia felt the hairs on the back of her neck standing up. Turning around, she found Tom Riddle staring at her. A shiver ran down her spine as Theia turned her attention to Orion.

Taking a deep breath, Theia headed over to Orion, Edward, and Anthony. At the sight of her, Edward moved from Orion's left over a seat, making room for Theia. She sat down and leaned against Orion's side.

Orion frowned, studying his betrothed. Theia looked tired with dark circles under her eyes. Why wasn't she sleeping? Was she worried about something? Orion racked his brain. He remembered there was something about Samhain in Theia's past.

It took a moment. Orion's eyes widened when he remembered. This was the day Theia's parents died, killed Voldemort. This was the night she became famous for surviving the night her parents were murdered.

"How are you?" Orion whispered, leaning into Theia's side. His gray eyes looked her over in concern.

Offering him a shrug, Theia's eyes dropped to her lap. She didn't know how to convey what she was feeling in words. Since learning the truth at the age of six, Theia no longer liked or enjoyed Halloween. Petunia and Vernon were all to happy to inform her that her parents died on Halloween. Of course, their story was far from the truth: James and Lily Potter died in a drunk driving accident that killed another family with Theia being the only survivor.

Orion frowned, but he said nothing as he wrapped an arm around Theia's shoulders.

Theia remained quiet as Orion returned to his conversation with Anthony and Edward. Every once in awhile, of the three would glance at Theia in concern.

"Time for the Feast," announced Libra as she joined the group.

Edward and Anthony stood up.

"I'm skipping," Orion announced, his arm tight around Theia.

"Alright," Libra said, a frown forming on her lips. Hopefully Orion would help Theia with whatever she was feeling.

Orion and Theia remained the couch as they watched their group of friends exit the common room with several other students.

Pulling out his wand, Orion cast a few privacy spells. Orion didn't want to risk anyone overhearing their conversation. It was no one's business. This was between Theia and himself – and his parents to some extension.

"What's on your mind?" Orion asked, his voice soft.

"Everything and nothing," Theia whispered with a shrug. She didn't know how to describe it. One moment she was wondering what her life would have been like if her parents lived and the next moment she was kicking herself. She had a family, now. She had Orion, Lucretia, Melania, and Arcturus. She had the promise of a future with Orion – Sirius, Regulus, and other children.

A frown grew on Orion's face. He didn't know how to respond to an answer like that.

Theia sighed. "I haven't liked Halloween since I was six," she whispered. "I don't have any good memories of Halloween."

Orion remained silent, simply listening to his betrothed as she started to talk. He didn't know too much of her past as Harri Potter. And to be honest, he didn't needed to know anymore. All that mattered to him was his place in Theia's life.

Theia started babbling about her various Halloween memories. She wasn't allowed to go "trick or treating" as a child – which Orion didn't know anything about. Her relatives were all to happy to remind her of her parents' deaths – their version of events, not the real thing. Her Hogwarts years had Orion's hair turning gray: a troll in her first year, the Chamber of Secrets in her second year, a criminal breaking into Gryffindor Tower her third year, being forced to compete in a deadly tournament her fourth year, and recurring nightmares her fifth year.

When Theia was done talking, she curled her legs underneath of her and she rested her head on Orion's chest.

Orion remained quiet, thinking over Theia's words. How could he comfort her? When he was younger, his mother would rub his back and she would tell him nice things that made him forget his troubles. So, Orion started moving his hand up and down on Theia's arm.

"Samhain is a day to remember the dead," Orion whispered. "Remember that your parents loved you. They loved you so much. They loved you enough to ensure your survival."

Listening to Orion's words, Theia felt something lifted off of her shoulders. Since learning about the prophecy, Theia had blamed herself for her parents death. While Orion never her parents, listening to him gave her a sense of peace and serenity.

Silence fell between the pair. Theia repositioned herself so her head was laying against Orion's shoulder. She closed her eyes, finding herself relaxed for the first time that day – in several days, really.

...

That night brought about a change in Theia and Orion's relationship. It grew more intimate, both emotionally and physically. Whenever they were seated next to each other, Orion and Theia would touch in someway, whether holding hands beneath the table in the Great Hall or leaning against one another in the common room at night.

They would tell one another secrets or something personal. Theia told Orion about Trelanwey's numerous death predictions and the predictions about Theia's children dying young. Trelanwey's predictions about her children dying young got Theia the most. Having her own family was a dream for her. It evolved over time, in her childhood it was someone coming to save her from the Dursleys and recently it was a husband and children.

Orion in turn shared his dread at having to marry his cousin, Walburga. Growing up, he got along with his cousin. They were friends. When they started Hogwarts, everything changed – specifically, Walburga changed. She went from a friendly young girl to possessive and hateful girl. As far as Walburga was concerned, Orion belonged to her.
