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.

A "nest warmer", DesertFlame is often curled around the egg nest, keeping the eggs at a constant and warm temperature. He has seen hundreds of eggs hatch in his care. Some dragons make fun of him because of his "soft" job, but they don't for long when DesertFlame's fire scorch them. Serious to his job, DesertFlame has chased off hungry predators and braced the cold wind to make sure no harm comes to the eggs. Although he will never admit it, DesertFlame has a soft spot deep in his heart for the eggs he cares for.
