These name ideas are great. As far as the gnome for a logo, it's a figure that environmentalists should aspire to be like. To be so attuned with nature that you can walk through solid earth as easily as humans can walk through air is pretty amazing in an ecological sense. If you erase the image of cheap plastic garden gnomes from your mind and think of any other gnomes you have witnessed, they are usually in a natural setting harvesting berries or plants or talking/riding wild animals (ie. connecting with nature.) This is the idea that I am going for, if there are other figures like gnomes that represent the same ideals then please go ahead and share them. As far as the name goes I would like to be a little less obvious with the gnome idea so that the name can stand alone without always having to have a gnome behind it. For example Earthen Creature is sort of like this and can be read on its own but with the gnome figure with it people will understand that a gnome is also considered an earthen-like creature.
