The Slytherins: mattheo riddle, Theodore Nott, Draco Malfoy, Lorenzo Berkshire and Blaise zabini. They are all in the common room messing with old artefacts they found in the restricted section of the library. When one weird looking ball held by Mattheo riddle, starts glowing and vibrating as he reads a script from a book. Suddenly there’s a flash. It has brought two different reality’s together. Now laying on the floor is you. Unconscious.
