Since theres already a map of aetheria (courtesy of poke), all we need to do is to show a close up of the city. do keep in mind however, that the infobox image slot is reserved for an actual photo of the location, not its place on the map.
Do we accurately know the location on the map of all the places? If so, then someone should be willing to edit the map and make images for each location. In that case it might work
Didnt i say poke already made a map? all one hast to do is crop/zoom in on a section of it. as for actual photos of the location, those can only come from ck himself or from his books.
