Art Sample: Tree Dungeons

We've cut down on the number of dungeons we've planned, at least for the time being. We'll be going with 6 dungeons rather than 10, at least for the initial set, and then see where it takes us. Instead monster species will share islands, at least for the time being, and have spawn chances based on those islands. If time and resources permit, we hope to boost that number of dungeons back up.
