I suppose my first thought on reading this one is that some kind of craft/trade group would do well. Shepherding, spinning, weaving. You'll all need socks. :) Also the creation of high-end trade goods. So they wouldn't be a martial group, but would have a lot of power through having skills that people needed. They'd probably be a small group living on some kind of highland/moorland with sheep and goats, but would be respected for quality tradeable goods. That's first impressions, anyway.
