Wish Upon a Star
Chapter XIV

When the Hogwarts Express pulled into Platform Nine and Three-Quarters, there was a mad dash to reunite with families and leave King's Cross. Theia followed Orion and Lucretia off of the train, each with the trunk shrink and safely stored in their pocket, as they headed off to find Arcturus and Melania.

After a few minutes of looking and pushing their way through the crowd of people, Lucretia spotted her parents. She squealed before grabbing ahold of Theia and Orion to pull them with her. Theia stood back as she watched Orion and Lucretia greet and reunion with their parents. Once Melania was done with her children, she turned her attention to Theia, who stood back. With a frown, Melania stepped towards the young woman and she pulled her into a hug. At first, Theia was stiff before she returned the hug.

Melania glanced over at her husband, who stood watching their interaction. Why didn't Theia understand she was a valued member of the family? This was something they would worry about later.

"It's good to see you," Melania said with a smile.

Theia returned the smile, but she didn't say anything.

"Grab on," Arcturus said, holding out a cane portkey.

With a frown, Theia reached out and grabbed ahold.

...

The Coastside Cottage wasn't a simple cottage. It was somewhere around a house in size. There was a kitchen, a dining room, two living rooms, two studies, a large library, a master bedroom, five bedrooms, and a four bathrooms. There was a view of the beach and the waves.

As soon as the Blacks arrived, Izzi and another house-elf arrived to take the children's trunks to their rooms. Theia followed Arcturus and Melania into further into the cottage. She glanced around as the couple led the three teenagers into one of the living rooms.

This living room was similar in size to the drawing room at Grimmuald Place with gray walls. There was a long black couch and a pair of black armchairs with a dark wood coffee table in the middle of the room. Arcturus and Melania sat down in the armchairs with Lucretia and Orion taking a seat on the couch. After a few seconds, Theia sat down in between Lucretia and Orion.

"We will be staying here for the duration of the holidays," Arcturus explained. "Even with the new wards, I feel it's too dangerous to return to London."

"What about this summer?" Lucretia asked.

"It will depend on the war," Arcturus answered, glancing over at Theia.

Theia closed her eyes and she thought for a moment. She never studied the Second War that much. She learned about it in primary school and she read some books over the summer to keep busy.

"I think the German bombing will be lighten up," Theia said, opening her eyes. "With the American in the war, things turn in favor of the Allied Powers but it's still going to be a long war."

Arcturus nodded, a mask of indifference settling on his face. "We will revisit the issue closer to summer," he promised.

"From April to June there will be attacks in some towns," Theia said with her eyes narrowed. She remembered a little about the Baedeker Blitz. She slowly listed, "Exeter, Bath, Canterbury, Lincoln, York, and some coastal towns."

"Any other bombings?" Melania asked. The London Blitz was a horrible nine months.

Closing her eyes, Theia slowly listed everything she could remember.

...

After the meeting in the living room was over, Theia headed to her room. She collected several things from her trunk – books, parchment, her Grimoire, and quills and ink pots – before she sat herself up in the library. It was time to work on one of her many projects.

Theia started off with adding more to her Grimoire. She was slowly filling the pages with her life as Harriet Potter. At the moment, she was somewhere in her second year. As she added information about basilisk when she dropped her quill, silently cursing at herself. With a wave of her wand, the ink stains were banished.

Standing up, Theia fled the library and she headed towards the living room. Hopefully Arcturus and Melania were there, if not then she needed to find them. With Hogwarts empty for the holidays, this was the ideal time to deal with the basilisk.

When she arrived to the living room, Theia found Arcturus and Melania were still seated in the armchairs. Arcturus was reading while Melania was embroidering something.

"I forgot to tell you something," Theia said, slightly out of breath.

Both Arcturus and Melania glanced up at her. Arcturus closed his book and he motioned for Theia to take a seat.

"What did you forget, Theia?" Arcturus asked, his tone gentle.

Theia took a seat and she fidgeted. It wasn't so much that she forgot that she didn't want to deal with this issue in question. There was a chance Orion mentioned it to one of his parents, but the lack of questions on their parts led her to believe that wasn't the case.

"I know where Salazar Slytherin's Chamber of Secrets is," she replied, "and I know what his monster is."

Arcturus and Melania shared a look. As former Slytherins, they knew the myths about the Chamber of Secrets, but like most people, they had written them off as nothing.

"What is the monster?" Melania asked.

"A basilisk," Theia answered, staring at the couple.

With their eyes widening, the couple shared another look. How could Salazar Slytherin think it was a good idea to place a basilisk in a school full of children?

"Why didn't you say anything earlier?" Arcturus demanded, his tone harsh.

Theia flinched at the sound of his tone. "I forgot," she whispered, her gaze dropped to her hands. "No one's ever really cared about the things I know and what I've done." Or me was silently added.

Melania glanced over at her husband and she motioned for him to leave.

Arcturus left the living room without a word. He had people to contact and arrangements had to be made.

Standing up, Melania walked over and she took a seat next to Theia. She placed a hand on Theia's back, causing the young woman to flinch. A frown crossed Melania's face. Some pieces were starting to fall into place about Theia and her life before.

"Of course, we care, dear," Melania whispered, rubbing her hand up and down on Theia's back. "If we didn't care, we wouldn't have you around."

Something about Melania's words triggered the memory of Theia's arrival.

"'We know you're not from our time,'" Theia whispered. "'What year are you from?'" She lifted her head and she glanced over at Melania. "How did you know I was a time traveler?"

"I was wondering when you would ask," Melania said. With a sigh, she explained. "The land Grimmauld Place sits on as been in the Black family for centuries and the land has some of the most advance wards – some are too advance. According to family legend, magic blessed the land. As a result, the land is something of a sanctuary. You're not the first time traveler."

Theia's eyes widened. She had never heard any of this before. She wanted to learn more.

"We care about you because you're a strong, caring young woman," Melania said, her fingers carding through Theia's hair. "You've been through so much and you haven't given up."

Melania sighed as she switched from carding her fingers through Theia's hair to braiding it. "At first, we were curious about the future and the knowledge you held," she admitted, "but we understood that you were lost and confused. You needed us more than we needed the knowledge you possessed." A few tears entered Melania eyes. "We love you. I love you," she whispered. "You've brought us so much and you've asked for so little in return."

Theia sat rather still as she listened to Melania's words. She started to cry at the sincerity of those words. Turning, Theia flung her arms around Melania's waist as she pulled herself close.

A half a second, Melania froze as she watched Theia, before she placed a hand on her back. Melania watched in silence as Theia cried in her lap. Gently, she returned to rubbing the young woman's back.

After a few minutes Theia stopped crying and she turned onto her side, moving head onto Melania's lap. Theia laid on the couch with her eyes closed. "You're the first person to say that to me," she whispered.

A frown crossed Melania's lips. She had said a lot, and she didn't know what part Theia was referring to.

"At least you're the first person I remember," Theia continued to say. "I'm sure my parents told me they loved me, but I don't remember. I only remember their deaths."

A wave of emotions overtook Melania. She almost wanted to cry, but this wasn't the time to cry over all that Theia had endured. "I know your parents loved you," Melania whispered, "trust me."

"I do," Theia whispered.

...

Dinner that evening was tense. Neither Orion or Lucretia knew what was going on, but they both knew it was something between their parents and Theia. Looking at his betrothed, Orion spotted the redness around her eyes. It was a sign she had been crying.

Once dinner was over, Arcturus took Theia and Melania into his study with Orion following behind. While Orion didn't know what was going on, he wanted to be involved. Clearly this was something important.

Arcturus stared at his son before turning his attention to Theia. "What can you tell me about the basilisk?" he asked.

Orion's eyes widened. "Are you talking about the Chamber?" he asked.

Both of his parents turned to look at him – Arcturus with narrowed eyes and Melania with disappointment.

"The question," Melania said, her tone hard, "should be why didn't you tell us about the Chamber?"

A blushed covered Orion's face. "I forgot," he admitted. "I learned about it at the Reunion."

Arcturus glared at his son while Melania pressed her lips together. Theia had told someone, but Orion failed to pass that information on. Melania would need to have a serious discussion with her son.

"The basilisk is over a thousand years old," Theia answered. "It only obeys the Heir of Slytherin."

Arcturus nodded, scribbling down a few notes.

"A basilisk can grow to be fifty feet in length," Theia continued to explain. "A typical basilisk has green skin, yellow eyes, and scarlet plume onto of the head, if male. Looking directly into a basilisk's eyes is deadly, but seeing the eyes through something else merely results in petrification. The venom of a basilisk is lethal, and the only known cure is phoenix tears. The easiest way to kill a basilisk is with the crow of a rooster."

By the time Theia was done, all three of the Blacks were stunned and they were staring at Theia.

"What?" she asked, her reddening. "I researched basilisk after my second year, and all this is in my Grimoire."

"How about the Chamber?" Arcturus asked.

With a shrug, Theia explained the only entrance she knew into the Chamber along with the details she remembered.
