Ceres is named after the Roman goddess of fertility/earth/harvest/etc. (equivalent to Greek Demeter), so I doubt Celes was based after her unless it was a mistranslation. I guess what FuSoYa is saying is that what is known to us now as the asteroid belt was once home to the race known as the Lunarians (that live on the Blue Planet's second moon).

I don't see what you're getting at with the dwarves though...?
