Hellfire Wyverns are so named for their foul tempers and fiery visages. Their social structure places all females above all males, due to superior physical characteristics and violent dispositions. Forced subservience of the males causes them to become vicious, petty, antisocial, and passive-aggressive compared to the aggressive and social females. However, orphaned hatchlings raised by foster parents of another species can develop surprisingly even tempers and mellow dispositions, proving that their defining unpleasant nature is, in fact, a learned behavior.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Akaanguka is a fell, heat-headed hellfire wyvern. She enjoys sitting in her nest above the volcano "Eyjafjallajoekull", sitting on her egg. She has a mate, and strangely enough he is a sunsong amphipteres, named Maliwanag. Maliwanag does not enjoy being above the volcano but still he gets the food for Akaanguka while she sits on their egg. The two are very opposite but the one thing they have in common brought them together. They both enjoy heat, Maliwanag was sleeping at the beach when he saw Akaanguka fighting a spitfire name Zumaridi. Maliwanag came to her aid and together they made the spitfire retreat. After that they fell in love.
