HNO consists of escaped servants. They won't attack player unless he gets to close to one of them. When they attack player, they apologize for doing so. They say that have to do so, because everyone wants to live and they are hungry. Therefore, after taking player down, they will loot them him/her to get cooked food.
Both escaped servants, and named outlaws may appear in Dreg. Unlike the servants, these named characters appear in small packs with attributes in the 7-12 region, and in perfect health.
