@Anon they cannot be hostile against something they don't know exists. They may be found on the surface but they are probably just scrounging for supplies. If you lived underground for hundreds of years you would probably be running low on supplies. Also they have no way of knowing about the larger cities such as Windhelm, Solitude, Whiterrun, etc, because anyone that got close would either be captured or killed. And I think it is safe to assume that they don't understand Tamrielic, so none of their prisoners can tell them of it. They are just a misunderstood race that is trying to survive, and their lack of supplies has forced them to turn to the surface. They capture humans because they have no idea that they are sentient, and relate them to mindless animals, much like the relationship we have with cows, pigs, and other sources of food.

P.S. It's The king of war. Only The is capitalized. Not trying to be a douche. I just like it that way.
