Harry enters King's Cross station to board a train to Hogwarts, where he meets three other students: Ron Weasley, whom he quickly befriends; Hermione Granger, an intelligent witch born to non-magical Muggle parents; and Draco Malfoy, a boy from a wealthy wizarding family, with whom he immediately forms a rivalry. After arriving at school the students assemble in the Great Hall, where all the first-years are sorted by the Sorting Hat among four houses: Gryffindor, Hufflepuff, Ravenclaw, and Slytherin. Although the Sorting Hat considers putting Harry in Slytherin with Draco, he is placed into Gryffindor alongside Ron and Hermione.
