Basadae
It’s said in the tribe of Basadae lived in India. They were men, with some that had heads of dogs, some with one leg or just one eye with skins so thick that arrows could not penetrate them. They were able to speak the language of the animals if they ate the heart and liver of a dragon, and could become invisible at will.
