Okay, its been a while since I read the story so some of what I write may be a bit vague or wrong but Harry is the heir of all four founders and lord of hogwarts (I think). He becomes an animagus (which is a panther) and starts a relationship Draco. The founders familiars also help him ,with Salazar Slytherin's basalisk (?) and Godric Gryfindor's lion sometimes becoming tatoos on his body and Rowena Ravenclaw's eagle (?) also eventually
turning into Harrys new transfiguration (?) teacher. Dumbledore is evil and has been damaging Hogwarts wards, but as Harry is in control of these wards he fixes them. Harry and Dumbledore also have a huge fight on the grounds of Hogwarts (I think). I dont know if anyone can help me find this story but id be forever grateful if they do.
