Wyvern

A wyvern was a large winged lizard with a stinging tail and sharp teeth. They had dark brown or grey bodies, around 15' (4.6 m) in length, weighing around a ton. They were not greatly intelligent although they did speak Draconic fluently. They were not averse to attacking anything less powerful than themselves. Their sleek, strong legs proved very useful for attack.

History
Wyverns were created by the aearee of Viakoo in −30,700 DR.

Uses
