Hey everyone. I'm currently working on developing the setting for my current fantasy novel and I'm having some issues with mapping my world. When I was younger, I used to create worlds without any thought as to how these worlds would work in terms of geography. For instance, I never considered that the presence of mountains would have an effect on the climate (e.g. the presence of a rain shadow). Now that I'm older, however, I find myself caught up in worrying about whether or not the world would work. So my question is...do you think it is important for the setting to 'work'? Or is it really not that important? And if you think it does matter, do you have any tips on creating a world that works?
