Invisiville is beautiful, populated with fascinating people in homes of spectacular inventiveness, with undiscovered cultural traditions. You can enter Invisiville through several similar passages, to see the varied parts of the city. Once you leave, however, you will not remember which passages you have used before. It is frustrating, as you want to see all of this wondrous city, without missing any, but you find yourself using the same entrances again and again. Your best bet is to put aside your itinerary and see all of Invisiville at once.
