I'm not sure what you mean by quests - do you mean guests? If so, the room below the throne room should be your oubliette. So both of your theories are correct. When they're standing on the trap door and you pull the lever, your guests drop down into the room below, which should be your oubliette. I don't quite get what you mean by this. When there are at least three floors in a building, and you are on the second floor, that's when you have the option to go up or down. Because you have a building above you and a building below you (both of which have staircases in the rooms above). But if you only have two floors in your house, when you're downstairs you'll have the option to go up, and when you're upstairs you'll have the option to go down. o... i mean guests.... that means it's not possible to build other rooms, but only oubliette, right? if there are three floors in a building, i can choose both climb up and climb down option on the middle floor, am i correct?
