This is a cache belonging to my Harry Potter series.
The Room of Requirement, also known as the Come and Go Room, was a secret room within Hogwarts Castle that only appears when a person is in great need of it.
The room is thought to have some degree of sentience because it transforms itself into whatever the witch or wizard needs it to be at that moment in time, although there are some limitations. For example, it cannot create food, as that is one of the five Principal Exceptions to Gamp's Law of Elemental Transfiguration.
The room is located on the seventh floor in the left corridor of the Hogwarts castle and has a hidden entrance opposite the tapestry depicting the attempt of Barnabas the Barmy to teach trolls ballet. The way to open the room is to walk past it three times thinking about what you need, and the door will appear.
When Harry Potter needed a place for Dumbledore's Army to practice:
Dobby: "Dobby knows the perfect place, sir! Dobby heard tell of it from the other house-elves when he came to Hogwarts, sir. It is known by us as the Come and Go Room, sir, or else as the Room of Requirement!"
Harry Potter: "Why?"
Dobby: "Because it is a room that a person can only enter when they have real need of it. Sometimes it is there, and sometimes it is not, but when it appears, it is always equipped for the seeker's needs."
It is advised that the users of this room be very specific about what they are looking for as other people can enter the room and see what the occupant is doing if they know how the room is being used. The Inquisitorial Squad found the hideout of the Dumbledore's Army in by knowing that the D.A. was in the room at the time. Harry used the room in his sixth year to hide the Half-Blood Prince's copy of Advanced Potion Making. Draco Malfoy finds and repairs the Vanishing Cabinet that had been stored in the room at some point. Later in The Deathly Hallows, Neville Longbottom used this knowledge to create his hideout as he specifically asked that the hideout be made unavailable to those who supported Alecto and Amycus Carrow.
The owner of the store is aware of a geocache placed in a way that makes your search seem natural, even if you do pace back and forth three times. Enjoy your search!
