Harry Potter OC Story Search

Hey there! I'm looking for OCs of all stripes to be in a story in which I'll throw my character, as well as all of yours that I pick, into a story of my own devising! The main character will be my own OC, but I need friends, enemies, rivals, Hogsmeade residents, animals, flying purple-people eaters, you name it! NOT A STORY. Kind of just my submissions office. Again, NOT A STORY
