Harry is an Investigative Auror with a disturbing past. After the war, he finds himself in love with his best friend Hermione, but he decides to leave her alone due to her relationship with Ron. Years later he meets Hermione, he finds her abused and unhappy. Both escape to the past trying to change the world for the better. Ron, Snape, Dumbledore bashing. Under strict revision...

Thirty-seven-year old Harry Potter looks back on his life and finds how worse the world has become, thus he goes back in time to save his seven-year-old self from an event that changes his life, to entrust his legacy to himself. May sound cheesy, but a different approach. Minor to major Dumbledore and Weasley bashing. Snape Bashing. Grey Harry, time-travel, A-Universe/A-Reality...

Typical Sirius leaves Harry a letter story trope. After Ootp but before HBP. Grey powerful Harry but just not overpowered and Grey Dumbledore. Definite Harry/Hermione pairing.
