I think it is a wonderful idea to have different species whether sentient or not.  If you think about Earth, we have TONS of species.  What is to say this planet is limited to just a few.<br/><br/>Just because Earth's species don't communicate, doesn't mean they can't.  I would assume (I know...never assume) that Novus would have some type of similaraties to Earth, otherwise the GM would have picked another planet...<br/><br/>You should see my barometer readings!!! whew  ::)
