Eventually a younger Albus Dumbledore came and took him to Hogwarts where Tom learned his magic . Tom became extremely powerful and eventually became the evil wizard Lord Voldemort . So Albus made an extremely massive mistake . In his school years , Riddle was a top student with a wicked passion for dark magic . He opened the Chamber of Secrets and released the Basilisk , which killed a girl who came to be known as Moaning Myrtle .

Harry was able to defeat the Basilisk with the help of the Sword of Gryffendor and Fawkes the phoenix , but got himself stabbed by one of the giant snake ' s deadly fangs . The fang came loose , and , in a final act of desperation , Harry stabbed the diary with the fang , destroying the Tom Riddle Horcrux and restoring Ginny to good health .
