There was a legend that Slytherin built a secret chamber somewhere in Hogwarts that only his true heir would be able to open. This chamber, called the Chamber of Secrets, contained a monster that would finish his "noble purpose" of killing all the Muggle-born students at Hogwarts. As Slytherin's heir, Tom Riddle did open the Chamber and released the monster, a Basilisk. Harry Potter defeated the Basilisk with the help of Fawkes the Phoenix and the sword of Gryffindor.
