Hadrian Arthur Slytherin Riddle

Completely AU. Tom never made an Horcrux : his sanity was too expensive of a price. He knew battles weren't won only by power. A sane Lord Voldemort makes a mistakes, but is it really ? It leads him to adopting Harry Potter, forgotten by his family. Hadrian Riddle was born. Dark/Grey!Slytherin!Harry. (Warning : I don't have the talent of the people on this website). Pairings (?).
