The Blacks and the Blues had been friends since the beginning, two of the most pure blooded families alive, how could they not be? Of course this meant their children would have to be close to each other. At least their eldest would have to be able to tolerate each others existence. Tolerate they did. Tolerate and more.
Sirius and Skylar were inseparable. Where one was the other was beside them. Where one went, the other followed. You rarely saw one without the other. And that is why, on this summer day, their parents had gotten together to discuss multiple matters and have dinner.
Skylar had a younger sister, Raina, and they got along fairly well. However just Sirius and Skylar sat in the parlor of the Black's manor, talking animatedly about quidditch. "Hey Siri?" Skylar had asked in a quiet voice. As if she was scared she would be caught, though she was doing nothing wrong.
Skylar had a normally loud and jolly voice, and was often told to be quieter and use an 'inside voice'. However when she was nervous or sometimes just calm, she would have a quiet voice. Skylar was an easily excitable child, and at 11 still hadn't grown out of it.
"Yeah? What is it?"
"You said you didn't want anything for your birthday-"
"Because I didn't" Sirius said, interjecting his statement.
"But I made you something anyway, as a celebratory gift."
"Celebrating what?"
"The two of us receiving our Hogwarts letters on the same day. So I made you something to fit the occasion."
Sirius had snorted, Skylar was smart for her age, and her use of long words had confused her parents at first.
"Big words shorty."
"It's not my fault you don't know what they mean you giant."
They both glared at each other and burst out laughing. This was how it always was, they were comfortable in each others presence, and loved making jokes. Skylar handed Sirius a small box, it was delicate and soft, black wrapped in gold. He opened it carefully, revealing a ring with the initials S.B. on it. The ring was golden, and the engraving was enchanted so the initials would change color depending on what house Sirius got.
"I love it so much. Do your parents know?"
"I'm glad. No, they don't, I thought it would be best."
The two hugged and Sirius noticed a ring on Skylar's finger as well. It looked identical to his, except her ring was silver, to differentiate. Skylar noticed him looking and explained that theirs were made to match. So that they would never truly be apart. And they wouldn't truly know why that would be special until later that evening.
A tragedy. That's what everyone was calling it anyway. How Sirius Black and Skylar Blue were going to different schools. Beauxbatons would be fun, or so everyone told Skylar. It was an amazing place for young women to learn proper etiquette. After a teary farewell Skylar left to Beauxbatons. Which unlike Hogwarts, didn't give a summer off, you had to learn how to be proper in summer as well.
And the two wrote letters at first, but eventually Sirius stopped writing. Stopped replying. And this tore at the heart of Skylar. Until she learned how to create a facade, of smiles, to hide the sadness that was growing. That had consumed her.
