"Here I definetly beg to differ. Halflings and hobbits are two widely different things. I think. Never read JRR's books, just watched the movies

Back in the late 70s, before there was an "advanced" D&D, they were called hobbits until the Tolkien estate told them to cease and desist. Likewise with "treants"/Ents.
As far as putting them into Dominions- I agree, you can get that stuff anywhere. When I found out that the Illwinter guys played a lot of Ars Magica, it revealed why a lot of things in this game are so solid.
Or maybe that's my pro-Ars Magica bias showing through.
