Eventually, the goal is to have a complete map. I hesitate to simply 'make up' my own maps, for the same reason that I would hesitate to make up my own Tolkien maps - both writers have very definite ideas about what their maps should show.
I've been playing around with trying to work from the descriptions given in the books. I make notes and sketches as I rediscover tidbits of data. If I feel I can get it right, I'll add to this map. A larger, interactive map is on the way.
Varley Vade mecum has a few maps of the other regions of Gaea. Love seein' Kong Mountain :)
