I want to create from scratch a map that resembles the world described in the novells "A Song of Ice and Fire". My map will have a similar coastline and will use some of the names of the places from the books.
Am I legally allowed to do that? Are there some restrictions to what I can do with this map (e.g. share it for non-profit purposes)?
EDIT
I have seen the map a while ago in a web site and I am recreating it from memory.
