Orpsu

Orpsu were fierce aerial predators. While they were sometimes called night stirges, they had no relation to stirges and were an entirely separate species.

Description
Orpsus lacked any kind of body hair and their spotted skin had a similar texture to leather. Their wide mouth had no lower jaw and was filled with sharp fangs. They had a long, thin flexible tail.

Their most distinguishing physical feature was their four "horns". Instead of arms or legs, an orpsu had four appendages that ended in a bone shaped like a sharp blade. A web of skin connected the appendages on each side of their body, which gave the appearance of wings.
