This wyvern lives in the caldera of an active volcano, constantly submerged in lava. The lava has formed numerous layers on its hide, allowing it to withstand any blow. This dark hide is known as "inferno scales". Even a single fragment if this ultra-durable material is said to be worth a fortune.

A wyvern, sometimes spelled wivern, is a legendary winged creature with a dragon's head, which may be said to breathe fire or possess a venomous bite, a reptilian body, two legs (sometimes none), and a barbed tail. A sea-dwelling variant, termed the sea-wyvern, has a fish tail in place of a barbed dragon's tail.
