A goblin whom Dobby helps Harry rescue from Malfoy Manor and, in the first Harry Potter novel, the goblin who showed Harry to his vault at Gringotts. Griphook is a hard individual for Harry to read, as he's both impressed by how kindly Harry treats non-human individuals in the magical world, but also seems to detest Harry and wizards in general. Griphook agrees to help Harry, Ron, and Hermione break into the Lestranges' Gringotts vault in exchange for the sword of Gryffindor, which was made by a goblin. He does, however, remain suspicious of Harry and aloof as though he expects Harry to double-cross him—a fear that isn't unfounded. Griphook escapes with the sword as soon as he gets the trio into the vault.
