Some of the Marauders Era characters, some of the members of The Noble and Most Ancient House of Black, some of the Noble and Most Ancient House of Potter members and some members of House Targaryen are gathered at Grimmauld Place to watch the life of Harriet "Harry" James Potter. AKA the first-ever female heir of the Potter Bloodline (because all of the Potters only bear male heirs and there hasn't been a female heir in centuries) and the only person in Wizarding history to have ever encountered the Killing Curse and survive with only a scar. Also known as the Master of Death by Thanatos.
