So, I'm 70'000 words into my first novel-length fantasy and I realise I need to change where some of the countries/realms etc are on my map, and therefore geography etc. Yeesh I thought ordinary revision was hard. I am a bit confused and trying to get my tired brain to work this out.. For those who make maps for their imaginary places- how do you go about it in a logical way? How do you decide what the needs of your story are? Or do you make a map first and make your story fit it? Any help apreciated.
