You know those suits of armors that sing Christmas carols during the holidays? Or the armors that bow, salute, whistle songs and such as students pass by? Well, the armory is where those armors go to be polished, cleaned, waxed or replaced. It is also where students like to go when they are being chased by prefects when caught out late at night. It's a simple process of finding the fattest suit of armor and hiding inside it until the prefect decides to give up. Now, getting out of the armor once the prefect gives up is a whole different matter.
