Feastmaster Tribe

The well-fed lowlanders of the Feastmaster Tribe are famous for two things: the quality of their food and the Halflings that live amongst them. Their heavily jowled Tyrant, Blaut Feastmaster, captured a string of the small folk during his many travels and, in a display of foresight and extreme self-control, brought them home for the lads instead of eating them then and there. The Halflings, in perpetual fear of ending up 'in the trough', fulfill much of the same role as Gnoblars, but in addition to fetching, they also help to prepare the food. As long as they keep making top-notch meals, the Halflings won't end up being a light snack themselves (probably).
