means of wand usage or physical force. In Harry Potter and the Chamber of Secrets, Harry intentionally destroys the diary with a Basilisk fang, although unaware it was a Horcrux at the time, to free Ginny from its influence. In Harry Potter and the Half-Blood Prince, the discovery of the diary is revealed as the proof that leads to Dumbledore beginning the hunt for other Horcruxes, as it not only gives absolute proof that Voldemort split his soul, but also that there were likely other, better-protected artifacts, given the risk Voldemort was taking by using the diary as a weapon.

Tom Riddle's soul-fragment possessed Ginny and, through her, reopened the Chamber of Secrets, eventually starting to draw her life from her. At the end of book two, Harry saved Ginny and destroyed the diary by stabbing it with the venomous fang of a Basilisk, making it the first Horcrux to be destroyed. His reports of the diary's behaviour to Dumbledore were the latter's first inkling that Voldemort might have created not just one Horcrux, but several: "What intrigued and alarmed me most was that the diary had been intended as a weapon as much as a safeguard", implying that Voldemort must have
