In a world, there will always be things that the commoners won't be able to gain access to. A luxurious home, a high status, glittering diamonds, etc. Then here is an obnoxious dungeon who only allows certain somebody entry of its bizarre abode on a whim. Do you have money? Do you have power? Are you an SSSSSSSSSS+++++ adventurer? If all of these is Yes, you are still not welcome.  The only question that matters is... What VIP level are you?
