Bestigor

The toughest of Beastmen are known as Bestigors. As well as being stronger, they tend to be more disciplined, forming more organised ranks in battle than their quarrelsome lesser brethren, and they restrain themselves from their more disruptive excesses. They always wield the best weapons and wear the best armour available to the herd, sometimes even using weaponry culled from the corpses of their enemies.
