Originally one of the four Protodrakes of Amos, the Wyvursan were intercepted by Coros during their release upon Basset. Stripped of their beauty and free will, Wyvursan were mutated into beings of pure hunger and terror. Their eagle wings had the feathers ripped off, leaving the leathering scaling skin exposed, and their upper bodies became bloated and over-sized with muscle and fur. They now resemble a horrific cross-breeding of an owlbear and a wyvern. 

The Wyvursan are on average 30ft long from snout to tail; on the ground they typically stand roughly 10 to 13 ft tall. They also have a nearly 20ft wingspan. Wyvursan arms are elongated like those of a bugbear, but are as muscular as an owlbear, with long hooked claws like a wyvern.
