What are the special places your characters like to visit in your fictional setting and why did they pick the ones they have? Are they allowed to go there or is tourism discouraged? What places are of national/global importance and why?
Different characters will also have different places that are special to them (though there will be some overlap with some places). So why has character A chosen one place and character B another? Do they fall out over this?
What is special about your fictional world as a whole? What makes you want to write about it/for it? What makes your characters happy to dwell in this fictional world?
