Tom Riddle's Diary

Tom Riddle's diary

Tom Riddle (later known as Lord Voldemort) created his first Horcrux during his fifth year at Hogwarts, using his own school diary. In order to cast the spell, he murdered his fellow student Myrtle Warren. In Chamber of Secrets, Ginny Weasley becomes possessed by the fragment of Riddle's soul that is encased in the diary, which compels her to open the Chamber of Secrets. At the end of the novel, Harry saves Ginny and destroys the diary by stabbing it with a Basilisk fang.
