Intelligence leads us to believe that a recent fist fight with a subordinate left Bre'geth with one less tooth in her head, and one subordinate permanently relocated somewhere else. Her bragging is well known throughout Zanaris, however, she is important to 'Bad Daddy's' plans. Without her, the ork warrior grunts would simply be fighting each other and their superiors. She keeps them in check. Suggest first talking to Bre'egth - she's likely to recount the entire story to you if you ask. The trouble might be in getting away afterwards.
