In any city, in any country, go to any sizable school or university you can find. After locating the front desk, walk up to it and ask to see the one known as, "The Holder of Extravagance". The attendant will look unfazed, even slightly bored, as though this question has grown so common as to become routine. Tiredly, they will rise and lead you through the halls of the building. You will see many dozens of unboundedly fascinating and eye-catching objects, but do not once stop or slow to examine any of them in closer detail, or the group of supposed students who have been following you will take the opportunity to pounce, and you will never see the outside of the walls again. Instead, stay focused on following the attendant.
