Dark Lumina Dragons received their names from their highly reflective scales, which—at times—seem to glow. They are vain, always strutting about and preening incessantly; if one of their scales has so much as a scratch or a defect, they’ll remove it. Luckily, their scales grow back quickly, and each new growth is more beautiful than the last. These narcissistic dragons live in small groups and prefer to surround themselves with beauty. The males guard their territory and eggs while the females search for meat to eat. Dark Lumina Dragons are much meaner than their cousins.

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.

Stygieul, at first glance, may appear as a vain creature, grooming and preening himself when presented with a reflective surface of any kind. However, beneath that exterior, he's a majestic beast. Flying at speeds of up to 120 mph, Sierra has to admit that this black dragon is a sight to behold in battle. His high-speed flight disorientates enemies and allows for attacks to hit straight to the core, especially during night battles. He gets along only with his parents and no one else.
