ok so I got this idea in the middle of the night... And I wrote it down in my phone! And now I'm posting it! Hope you like it!
Chapter 1: The spell
Harry, Ron and Hermione were hanging out in the Gryffindor common room one boring, rainy evening before bed. All the others had gone upstairs to bed, probably because of the soothing effect the sound of rain had, or just simply because it was a long day of school.
Harry and Hermione were engaged in a very deep conversation about whatever they were talking about, and Ron and been shoved to the side. So, to contain his boredom, he had begun flipping through some of Hermione's advanced spellbooks.
Of course, Hermione wasn't even officially allowed to practise those spells. But, instead of spending her pocket money on sweets and clothes, like other girls her age, she bought big, heavy books about extreme subjects and read them. For fun. Such a nerd.
Flipping to the back of one of the aforementioned books, Ron found a spell circled in red, labeled, "WARNING! USE ONLY WHEN ALONE!" The spell read, "supervehor ouraniam". Needless to say, this aroused his curiosity. Perhaps because it was a spell he'd never heard of before, perhaps because of the warning, written in red, no less, but he decided to try it out.
If you're thinking that wasn't very smart, forgive him. It was a bit late, he wasn't thinking properly. Either that or he's just a jerk.
He recited the incantation in his head a couple times, using the proper enunciation outlined in the book. He practised swinging his wand around in an infinity symbol, like the neat, precise handwriting on those pages proclaimed. He then felt he was ready.
"Hey guys," He called, to get their attention. They turned around. "What, Ronald?" Hermione said in an annoyed voice. "Supervehor Ouranium!"
Immediately, the world started to spin. "Ron!" Hermione shrieked. "You asshole!" Fog began to cloud in thick, and Ron's ears started to buzz. "What's going on?" Harry said, looking around confusedly. The world spun faster and faster, and fog clouded their view until, with a thump, it all stopped.
