Did a quick redraw on a few bits; the new areas here are (1) and (5) from Rossum.
1) Is the whole island chain; shrublands biome with loads of caves, underwater passages.
5) Is a bay lined with wetlands forest - huge trees that grow right up from the water, like mangrove/cypress/baobabs; vine-covered in many cases, and big enough to build a house in their branches.
