AU. Salazar Slytherin once left Hogwarts in disgrace, vowing to return. He kept his word. A thousand years later he rules Wizarding Britain according to the principles of blood purity, with no end to his reign in sight.

... How I Learned to Stop Worrying and Love the Cruciatus. Albus Dumbledore always worried about the parallels between Harry Potter and Tom Riddle.

Neville is the Boy-Who-Lived, Harry Potter just another orphan. Without the scar on his forehead Harry is free to choose his own path. His Slytherin sorting is only the first surprise to his parents' old friends. Darkish themes. Dark!Harry. Rating could go up to M later.
