"But the fake sword isn't the only thing in that vault, is it?" -- Harry Potter
The Lestrange family vault is a high security vault in Gringotts Wizarding Bank. A dragon guards its entrance and rather than just placing a finger on the vault door, a goblin must place his entire palm to the door in order to open it. The vault is filled with gold, the fake sword of Gryffindor, armor, skins, and potions – and most importantly, Hufflepuff’s cup, which Harry steals (DH26). The objects in this vault have a Gemino curse placed on them to prevent would-be thieves.
