So this is it's mother! These wyverns have very thick forearms for a very good reason! The rear of their arms are a combustion chamber for a valved pulse jet system that works from vents on the sides forearms! It's all fueled by highly flammable fluids their body creates in only certain amounts, so it's used only for cruising altitudes, hunting, and emergencies when needed!
