@The King of War - Actually, the falmer can be found on the surface in several locations, as it says on this very wiki. In addition, during the main quest a journal can be found that notes the findings of a man researching the falmer (most notably by living underground with them) that comments on their increasing aggression and the massive threat they pose to the surface world. Considering this is not elaborated upon or brought to a conclusion in the main quest line, it suggests to me that it will resurface as a plot point in some DLC.
