Leaving the Color Sims, I've entered a region named after Micronesian gods, which I dub Micronesia. This web page is the only one I can find with all the Micronesian sim names, so perhaps the Lindens used it as a reference?
Rua is a Tahitian god of craftsmen.
This set of flying islands is quite spectacular. Unfortunately the constraints of my quest mean I can't fly up to inspect them.
