Hagrid, a giant man arrives. He introduces himself as the Keeper of Keys and Grounds at Hogwarts. He finds out Harry knows nothing at all about his past and his parents' world, nor that his parents and he are magical and he is famous. Hagrid gives Harry his invitation to enter Hogwarts, a school of witchcraft and wizardry and his booklist, signed by Deputy Headmistress Minerva McGonagall. Harry is amazed to learn that he is a wizard. Hagrid tells Harry about his past, his parents and about the dark wizard Voldemort who killed them, along with other of the best 'good' witches and wizards, like the McKinnons, the Bones and the Prewetts.
