Chapter 1: Vault 713
Vault seven hundred and thirteen had no keyhole. "Stand back," said Griphook importantly. He stroked the door gently with one of his long fingers and it simply melted away. "If anyone but a Gringotts goblin tried that, they'd be sucked through the door and trapped in there," said Griphook. "How often do you check to see if anyone's inside?" Harry asked. "About once every ten years," said Griphook, with a rather nasty grin.
A thought occurred to Harry. "Er, Hagrid? If the You-Know-What is really important, why is Professor Dumbledore making it easier to get to?" Hagrid paused, his hand hovering over whatever was in the vault. "Wha' d'ya mean, easier, Harry?" "If someone who isn't a Gringotts goblin tries to open the vault gets sucked inside and trapped there, and they only check to see once in ten years – anyone who tries to steal whatever's in there would starve to death before they could ever get out!"
Hagrid straightened up, drawing in a long breath of surprise. "Blimey, Harry, I reckon Dumbledore 'imself wouldn't 'ave thought o' tha'! You'll probably end up in Ravenclaw, comin' up with things like that!" He turned to Griphook. "I'll 'ave to talk to Dumbledore about this. Can we go back now, please, but slower?" "One speed only." Griphook said.
***Time skip***
When the school year began, there were two main topics of discussion among the student body. The first was Harry. The second was Professor Quirrell. Nobody had seen or heard of him since Harry and Hagrid encountered him at the Leaky Cauldron. Eventually, there was an answer to the mystery. On September the 22nd, the headline of the Daily Prophet was "Hogwarts Professor Found Dead In Gringotts Vault!" The article detailed how Quirinius Quirrell had been found dead of starvation inside Gringotts vault 713. A quote from one of the goblins was quite funny, in a morbid sort of way. "It says you may find more than treasure there on the door for a reason. One of the things a thief may find in Gringotts is death, in all sorts of painful ways, some faster than others."
