Not really. Not at the start, anyway. All map making starts from somewhere. Star Trek? Earth, you pin that on map, put the nearest real star systems you want, then basically throw darts at the map and where ever the dart lands is system for X species. Star Wars is basically the same. Coruscant is hub of the Republic/Empire, it is a core word (kinda literally since it was close the galactic core) that's your starting point. Then you just do the same. Unless you have specified the distances, then it is slightly more annoying, but not really a problem.
Even when established and you have the whole map "up to date" there still will be large gaps. Just put something there and done. In here it would start from Qishu. It's seven days on foot to the Grayguard village to the north/north-east, that's a maximum of 210 miles. Note humans can travel 20 to 30 miles on foot depending on resting times, terrain, weather, etc. Horses can do 30 miles if I recall correctly per day. Specifically trained horses can do 100 miles a day, but will need several days' rest afterward or they die. After you pinned the places that are known (distance wise) then it is just placing the rest, easier if you haven't specified the distances too clearly.
