’m currently wracking my brain for the name of a fic. The points I remember are: Harry has a twin brother who is pretty much awful; Harry has his magic suppressed by James; he starts hogwarts in 4th year after breaking free from the suppression; he’s sorted into Slytherin, which makes James furious - he disinherits Harry at some point; it turns out Harry is in fact Sirius’s son and not James’ - which is why James always hated Harry; in part two, after Voldemort is defeated by a Slytherin I can’t remember the name of poisoning him in some way and sacrificing his life to do so (he is a death eater spy for Harry), Dumbledore finds Harry and attacks him, and I think Harry defeats him by using his animagus form, which is something like a lightning phoenix. I definitely read it on Ao3. Any help you can give would be greatly appreciated, and thank you for all the work you do trying to find fics
