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.

Nightfang Deathwing is quite friendly, due to her being raised by friendly dragons. A human would probably describe her cave as 'Gothic'. It is large and dark, made of black stone. Torches that burn with a strange blue flame are set at intervals around the walls, some set on stalagmites that protrude from the floor. Bones and skulls from various animals are set around the cave, some gathered from other places, some from fallen enemies, or those who tried to thieve from her hoard. She doesn't collect much gold, preferring gems. Her favorites are any big crystals, regardless of value. Despite her ominous cave, she's really quite welcoming to those who don't mind the creepy atmosphere.
