Thank you greatly, Monks. Your insight is true about the setting for his languages.

In a sense, I have a bit of tendency to create new languages to help create the worlds of my stories. After all, for Tolkien, he used the natural world around him to create his world for M-E and the peoples that inhabit it.

Geology and science may not be my ultimate answer while creating my stories, but it is a driving force for me. Only once have I ever made a map where higher-power took precedence.
