Harry spoke up, "The most important thing is that we locate the horcrux before You-Know-Who does. The only way to destroy him is to destroy those first. We have reason to believe one is hidden at Hogwarts and another is possibly located in the Lestrange Vault at Gringotts. We were able to destroy the last horcrux in our possession with the Sword of Gryffindor but it was unfortunately lost at Malfoy Manor."
