The door creaked and groaned under its own weight, protected by layers of magic. Hermione and Luna tried to walk through the door and found they could not, the vault remained open but an invisible barrier held them back. Theo on the other hand was able to scuttle in beneath Draco’s legs as he too stepped into the gloom. "It's probably spelled so you can't get in unless were - married. Mother adopted Theo, I imagine this is confirmation that I am not the only heir." He surmised for Hermione's curious gaze. He could hear Theo tinkering in the vault behind him, searching through the piles of wealth for a golden cup.
