Patron Idea Post (With a Twist!) (Patreon)

It's time for this months Patron Idea Post. For those of you that are new, this is your chance to post your ideas for me to turn into a oneshot. Ideas must be HP, Harry-centric, and not violate Patreon's terms of service. In a week, I'll pick my 5 favorite ideas and put them in a poll for everyone to vote on. the winner gets their story turned into a oneshot by the end of the month. This month, I want to challenge you to something different. I'm looking for ideas that feature OC's, or rarely used characters. You don't have to post those if you have other ideas, but that's what I'm going to be looking for this month. Good luck and have fun!
