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.

High-strung like his genetics predispose him to be but not at all nasty to strangers, Set'iytrop has an unusual occupation for his species, which goes hand in hand with his unusual upbringing. Snatched as an egg from the depths of some forgotten cave, he was raised in the courts of a sickly prince to be his protector from opportunistic assassins and perhaps even inspire the prince to rise above an ailment he had. Indeed, Set'iytrop's flame and aggressive nature helped his new master flourish, and today the man is now king and enjoys being guarded by his watchful friend, who roams the palace grounds and likes to perch atop the castle. Set'iytrop lets no other but the king pet him and enjoys basking in his position as the king's Royal Protector.
