If I am not mistaken, this is a project whereby you, intrepid mapper can aid in the designing of a Fantasy World, utilising whatever mapping style you like.
As was suggested earlier in this thread, because all of us here have different mapping styles, we are not going to stick to any one style, but let mappers use their own unique styles. If you wanted to 'invent' a fictional persona (Like the Forgotten Realms Marco Volo for example) to be the mapper, feel free.
We are setting up a main world so there will be a cohesion between the various maps, but not necessarily the style.
