"The marriage contract I drew up for Harry and Ginny. I also illegally sealed the Potter wills, in them it said Harry was never to go to Petunia. I told everyone I was his guardian, which I am not. Narcissa Malfoy is his guardian for some reason. Couldn’t have that found out, so I sealed the wills. I knew Narcissa would love him like her own son and raise him properly. I needed Harry to be ignorant of the magical world and our ways."
