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.

Since nobody else would suck it up and do it, Toothpaste has to be the "motherly" figure to all the eggs and hatchlings. However, being a Hellfire Wyvern, she's not particularly "motherly."

She'll make the hatchlings face off: newborn against newborn, mature hatchling against mature hatchling. When they become full grown dragons they're usually tough and beefy all because of Toothpaste.

But at least they aren't helpless!
