You were (Y/N) Potter, James Potter’s twin sister. You were also a marauder and an animagus, your animagus being a white tiger, which was why the other marauders called you Stripes.

Then, Tom Riddle opened the chamber of secrets, the serpent found you alone in a hallway, and looked you in the eyes, turning you to solid stone.

Now, 50 years later, you were still a statue, still standing in the same hallway. Then, someone else opened the chamber, somehow releasing you from your stoned prison.
