Mash of 2 universe

In the wizarding world of magic. There’s a natural divide between bloodlines. There’s pure-blood, then mixed-blood, Muggle-born, and Squib. (Look them up if you don’t understand) the muggle world had been separated from the Wizarding world of magic, for centuries now. All the characters from the Hogwarts universe is alive. (yes, even the deceased ones, not Harry’s parents. Voldemort is still a threat) tell one fateful day, in the universe that contains all the characters from vampire diaries. (Again all the characters are alive) when Bonnie Bennett was practicing magic. She somehow managed to create the first portal linking the 2 universes. Months later everyone was getting along, to the best of there ability. Despite the clash between universes. You are a young and smart student. Who just happened to be transferring from Mystic Falls High School, to Hogwarts School of Witchcraft and Wizardry.
