Bray

At the bottom of the herd are the Brays. These are Beastmen with no horns at all. Even the Ungors look down on these pathetic creatures, mocking them and bullying them at every opportunity. Brays rarely live for long, being the last to gain food and always the furthest from the warmth of their encampments. Brays take their name from the braying, whinnying, whooping cacophony they make when they band together to eat or kill. Though these wretches are amongst the weakest and most worthless, it’s not unheard of for a Bray to use his cunning and bravery to assume control over a herd. Such occasions are brief, as the Bray must constantly fight off challengers to his rule.
