Either way, there is the problem that it could potential step on toes regarding copyright though (IANAL so I don't know how much of a problem this would be for sure.)
As long as we don't directly copy anything I think we should be OK. The creation of a map that doesn't exist in the books (or anywhere else) could at most be considered fan art, and it certainly seems to be "fair use".

We could also go for any published fantasy world but IMO it's somehow nicer if the maps have a common theme. Of course, as Jaxilon points out, people who didn't read any of the books will not find the challenge that easy. They will either have a bit of reading to do or they can just submit their latest village. The world is big enough that almost anything goes.
