Hey, I have the same book and the same situation. Would you mind sending me the files too?
As for other "Enhancements" to the setting, there is another book that I own but which is not within reach that is part of the same setting. Beneath the waves or something like that. It is a green/teal book with the worst drawn mermaid i've ever seen on the cover along with the MSRP. It details the underwater area around the Bluffside crater and their enviromental conflict with the Steam Gnomes. New player races, and a coral based spellbook system.
