Harry then leads Ron and Hermione into [Mr. Ollivander]'s room, where they learn of wandlore, and the fact that Harry is now the owner of Draco Malfoy's [wand]. Harry also confirms that Voldemort is indeed after the [Elder Wand], and that he went to [Gregorovitch] to find it. Finally, he asks [Ollivander] about the [Deathly Hallows], and when Ollivander has never heard of them, Harry, Ron, and Hermione leave him in peace.
Finished with Griphook and [Ollivander], Harry leads Ron and Hermione into the garden, where he tells them of how [Grindelwald] stole the [Elder Wand] from [Gregorovitch]; was conquered by [Dumbledore]; and, ultimately, how the [wand] ended up in Dumbledore's tomb - and as he talks, Harry watches in his mind as Voldemort, having made the same discovery, breaks the tomb open and takes the world's most powerful wand at last.
Griphook informs Harry, Ron, and Hermione that he is willing to help them break into the [Lestranges]' vault at [Gringotts] - on the condition that they give him the [Sword of Gryffindor], which he claims was stolen from a goblin. The trio then leaves the room to discuss what to do.
Time passes with Harry, Ron, and Hermione spending much of their days shut up with Griphook, planning to break into [Gringotts]. Griphook wears on the trio, and on the rest of the family, but Harry realizes there is simply nothing else to be done.
