Belgoi

At first sight, the belgoi appear human–and then you notice the long claws on the end of their fingers, their puckered toothless mouths, and their webbed, three-toed feet. They are a race of ignorant demi-humans who dwell in the most forlorn wastes of Athas. They have a taste for the flesh of intelligent races and no ruler will tolerate them within five day’s travel of his or her city.
