Based on the challenge Changing the Past by shigeki11: Severus and Harry have survived the final battle, however on the very night as Hogwarts sleep a Dark Lord from the past resurfaces and Hogwarts is destroyed. They journey to the past and adopt the toddler Tom Riddle in order to save the future. How much can they really change when some things seem destined to happen. Set partially during World War II where conditions of war exist; implied rape, implied torture though not of main characters (nothing graphic). Bad Dumbledore. Implied Dumbledore/Grindelwald.

Firenze and the other centaurs didn't rescue poor Harry that night in the Forbidden Forest when he came face-to-face with James and Lily Potter's murderer, Voldemort. Draco did, though. Struggling to cope with the attack and the fact that he nearly died, Harry learns a little about himself and regains something he thought he'd never have.
