I don't own Harry Potter.
When Luna was seven was the first time that she got to see her mother inventing a new spell. It wasn't just the calculations and the runes and everything else that you had to plan out before you created a spell. No, this was the real thing, the time when Mummy reached out to the very core of magic itself and manipulated it into a rigidly defined spell. That was part of the reason that Mummy and Daddy worked so well together.
Daddy was the one that connected with the wild side of magic. He understood how to manipulate it and make it do what you wanted it to while keeping it at its powerful first form. Mummy was the one who could hold back all of that power, to force it through a tube and make it just as powerful as the first stage. The both had a hand in creating spells, but Daddy mostly helped with the boring stuff, like runes and such. Mummy was the one that got try the spell out first. Mummy was the person who tweaked and made sure it worked okay.
Luna thought her mummy was amazing when she created spells. The magic danced around her and made her hair glow from the sheer intensity of it. And mummy was always so happy when she was making spells. Joy lit up her face, and it made her look even more stunning than it already was, and Luna knew her Mummy was stunning.
When Luna was nine, she saw her Mummy die. She'd been making another spell. Luna had known it was a special spell too. She'd heard Mummy and Daddy whispering about it late at night when they thought she was sound asleep, not waiting outside the kitchen door to make sure she heard every word they were saying.
Everything had been going well at first. Mummy had been happy, so happy, once again. The magic was making her hair glow, and the spell was coming out of her wand. But then something went wrong. Luna could tell by the way that Mummy's face dimmed. Usually Mummy never stopped smiling like a Christmas tree fairy when she was making a spell, but now she wasn't. Her smile wasn't so happy. There were worry lines in her forehead.
The next sign that something was going wrong was when Daddy tried to get her to leave the room. Since she was seven and they had deemed her old enough to watch, Mummy and Daddy had never tried to get her to leave the room. Daddy kept insisting, but Luna punch and screamed and had a fit, so they let her stay. Well, Daddy had let her stay. Mummy was busy with the spell that was rapidly beginning to grow bigger and bigger.
The other sign that something was going wrong with the spell was when Daddy joined Mummy with the spell. Never had she ever seen Daddy try to help Mummy with a spell. When she had asked why Daddy one day, he had said that it wouldn't work for one person of he helped her, because the amount of people who made the spell was the amount of people who had to cast it to get it to work.
The next sign something was wrong was when Mummy and Daddy started crying. Mummy's hair was becoming blinding, but Luna could still make out every detail. There were tears streaming down their faces. This was bad. Mummies and daddies weren't supposed to cry. That wasn't how things worked. The only times mummies and daddies cried was when something really bad happened, like grandma dying.
The final clue that something was wrong was when Mummy disappeared in a big burst of light. Surely Mummy wouldn't play a joke during such an important time. She looked around. There was nowhere Mummy could be hiding, and Mummy couldn't have gone pop, because there were wards for that. Luna looked up at her daddy. "Daddy," she asked, "Where's Mummy?"
Daddy chocked a little before her could say it. "Mummy's gone."
