harry potter one shots. mostly drarry, maybe some jegulus. pansmione?

the 7 + Nico, Rachel, Will, the Stolls, Katie, Thalia, Magnus, Alex, Sadie, Walt, Carter and Zia are send back in time to the day before percy was claimed as a new threat arises, putting their younger selves in a position in which the can't defend themselves. How will our heros manage to best this threat, and just how much are they willing to sacrifice along the way? This story can't be qualified as original due to the fact that i am not rick riordan and do not own any of the characters. there will be no OC's in case you're like me and it annoys you when authors add them. ( except like idk a monster or something. no one that matters ig)
