What would happen if anyone but a Gringotts employee tried to open vault seven hundred thirteen?
What would happen if anyone but a Gringotts employee tried to open vault seven hundred thirteen? According to the goblin Griphook, if anyone but a Gringotts goblin tried to open Vault 713, they'd be sucked through the door and trapped inside the vault until the vault was opened (which Gringotts goblins did once every ten years). Based on this, Disapparition was more than likely impossible from within the vault.
Who killed Griphook?
Later he is killed by Voldemort after the Dark Lord learns of the break-in at Gringotts.
