I have the Dragonborn dlc and the Bend Will shout. When I use it on dragons, they will land for me and I can ride them. But it seems that the only thing I can do with them is attack other creatures. How do I get the dragon to fly to a location without quick travelling? Or is this impossible?
As @Kevin has pointed out in the comments and the Wiki points out, it's not possible to actually specify a location for the dragon to travel to. In this sense: the dragon is not a mount. You are able to fast travel on the dragon (but you cannot travel between Skyrim and Solstheim) as you would normally.
