Wish Upon a Star
Chapter X
The next morning, numerous Slytherins were watching Theia Johnson closely. No one had heard of her before the Sorting. She had a mudblood last name, she spoke Parseltongue, she acted as a pure-blood, and she was betrothed to Orion Black. She was a mystery.
Among those watching her was Tom Riddle. He wanted to know more about her. The other Slytherins were assuming she was the Heir of Slytherin because she spoke Parseltongue. No one in Slytherin knew Tom spoke Parseltongue. He was keeping that ability secret until he was made Prefect next year. Between the rank of Prefect and his Parseltongue abilities, he would become the new leader of Slytherin, replacing Orion Black.
But Theia Johnson ruined that – all of that.
As he watched her, Tom started to grow obsessed. He needed to know everything about her. Her presence in Slytherin was ruining his plans.
With narrowed eyes, Tom watched as Theia left the common room with Orion Black, his friends, and the sixth year Black cousins – Virgo Black, Libra Rosier, and Aries Nott. That group would remain in charge until their graduation, then leadership would fall to Lucretia Black by default since she was Orion's sister and a member of the main Black line.
Unless something could be done. Tom would need to do something, but he needed to study his prey.
...
Theia was less than impressed with the Head of Slytherin, Horace Slughorn. He was a young looking man with a blonde mustache, blonde hair, and large proportions to his body. While passing out the schedules, Theia noticed the man had favorites. Theia was glad she wasn't among them.
As he passed Theia and her friends, he simply handed out schedules with minimal talking before moving onto the next group, where he struck up longer conversations.
"They're members of the Slug Club," Aries Nott whispered, disgust in her voice.
"It's a club made up of Sluggy's favorite students," Libra Rosier explained with a roll of her eyes.
"Basically," Virgo explained, "Sluggy's favorites are students he thinks have bright futures ahead of them."
Theia nodded. That didn't sound like something that interested her. As a professor, Slughorn should encourage all of his students instead of focusing on select few. She smirked, taking note of whom Slughorn had selected. Theia knew some of the brightest of this generation, and so far Slughorn's guesses were wrong.
"Let's compare schedules," Theia said, changing the subject. Looking down at her own, she found she was content with it. She was only taking seven classes: Defense Against the Dark Arts, Charms, Ancient Runes, Arithmancy, Potions, Transfigurations, and Magical Studies.
The four girls talked as they compared schedules. They had two classes together: Defense and Charms. Other than that, Theia shared Ancient Runes and Arithmancy with Aries, Potions with both Libra and Virgo, and Transfigurations with Virgo. Theia was the only member of the group taking Magical Studies since the others had Muggle Studies.
A few minutes later, Orion, Edward and Anthony joined them with their schedules. Orion and Anthony joined the girls in Defense and Charms. Edward and Orion joined Theia in Transfigurations and Potions while Anthony joined her in Ancient Runes and Arithmancy.
"I don't see why we have to take Muggle Studies," Edward Nott said, grabbing a piece of toast. "Who even came up with the idea?"
Some of the others agreed.
"Lord Black," Theia answered, drawing the group and some surrounding Slytherins' attention.
"But why?" whined a fifth year girl with dark hair and a pug-like nose.
Theia glanced at the younger girl. She had to be related to Pansy Parkinson. They're noses were practically one and the same. "He saw my O.W.L. result," she explained. "I passed with an O."
A few Slytherins muttered something about blood traitor and mudblood lover, but they were ignored.
"The test is so easy a five-year-old muggle could pass it," Theia explained. "The old textbook – The Muggle Experience – is horribly outdated. It's hardly mentions electricity."
Theia paused for a moment, "And don't forget muggle-born and muggle-raised students are now taking Magical Studies."
Conversations broke out amongst the Slytherins. Several of the pure-blood were pleased to learn the muggle-born and muggle-raised were learning the proper customs and traditions of their world, but they were far from happy about taking Muggle Studies.
"I still don't see the point," commented a sixth year girl with pale blonde hair, green eyes, and a round face. Theia recognized her as Athena Malfoy. She would one day marry a muggle-born Ryan Chase, and she would have a promising career in Potions before her death at the hands of Death Eaters. Some believe she was killed by her nephew, Lucius Malfoy.
Theia thought for a moment. "Would it interest you to know the muggle fashion industry is worth several million pounds, worldwide."
That caught several female students attention.
"Muggle designers release new clothes each year," Theia explained, hoping she was correct. Her information was from the 1990s, but the fashion industry had to be old. "They're are new trends and new styles."
"Really?" asked Athena, green eyes wide in curiosity.
Theia nodded. "I can get few magazines to show you," she offered.
"What's a mag-zine?" asked a seventh year girl with brown hair, an oily face, and large teeth.
"Magazine," Theia corrected. "It's a small book full of pictures and advertisements – but none of the pictures move," she explained. She might want to look into a potion that made muggle pictures move.
"Can you, please?" Athena asked as several girls nodded.
"Sure," Theia agreed. Hopefully, Izzi wouldn't mind running a few errors for her.
Conversations changed to excitement.
"Will help us with our homework?" Aries asked.
"Of course," Theia replied.
Theia left the table a little later. She took her schedule and head back down to the Slytherin common room. Her first class was in almost two hours.
...
The first week of classes went by quickly. Theia attended each one of her classes, impressed the professors with her knowledge, and she did her homework in timely manner.
It was strange being back at Hogwarts without Ron or Hermione. Theia kind of missed them, but she didn't miss being Harri Potter. She was happy to be Theia Johnson. Being at Hogwarts with Orion, Lucretia, and the Black cousins was interesting. Libra, Aries, and Virgo were excellent roommates and friends. The three of them were better than Lavender Brown and Pavarti Patil as roommates.
Theia found the politics of Slytherin to be interesting. Since Orion was the King of Slytherin, she was the Queen of Slytherin. Theia wasn't certain who the prince and princess were, but she was willing to guess Lucretia was the Princess of Slytherin. The identity of the prince was a mystery.
Since Theia was the Queen, everyone in Slytherin treated her with respect. She wasn't foolish enough to believe that might everyone liked her. Her experience as Harri Potter with the media was fickle and with it people. People would say and act one way in front of her, and another behind her back. She knew this would be no different.
None of that really matter. Theia knew who her allies were, and she had an idea of who her enemies were.
The top of her enemies list included Walburga Black and Tom Riddle. Walburga's dislike of her was no secret, and Walburga didn't even try to conceal it. Tom Riddle watched her closely, and Theia knew when his eyes were on her. She knew Lord Voldemort well enough to know Tom Riddle. Tom Riddle was young, and he didn't have the experience of Lord Voldemort, making Riddle easy to watch. The rest of her list was made up of their allies. Riddle was the leader of the fourth years and he had a good number of the third years. Walburga had limited allies. Most people in their years sided with Orion, knowing the power he would wield as Lord Black. Interestingly, Cygnus remained neutral, either siding with his sister or his cousin.
