The phidian are small semi-aquatic creatures that resemble a bird to some degree. The creature's two legs are long, adorned with huge claws, designed to rend flesh. Their bodies are narrow, scaled on the underside, but covered in thick fur above. They have a short neck adorned with a huge head. The head, including the phidian's jaws, is actually one large hairless bone; this bone is so thick that it is very difficult to penetrate with a weapon. There are no teeth or fangs of any kind, but rather the very bone of the jaw. The creature's deep-set eyes are covered by boney apertures, protecting them from harm. The phidian are dark colors, shades of black, gray, even green, or blue.
