Seawyrm Pygmies are little dragons that live by the ocean, coasting on the winds above and diving down straight into the water whenever they spot a choice fish. Before their wings grow in, they spend the majority of their time in the sea, their tail fin extending over halfway up their bodies and allowing them to maneuver quickly and easily through the reefs. As they age, they give up some of their maneuverability in the water as that fin recedes into a tail fin better suited for flight. When a Seawyrm Pygmy finds a mate, they will perform synchronized dives together before burying their eggs in the shallow sands, where their eggs can hatch protected from larger predators.

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.

Pygmy dragons are the smallest category of dragons, being on the same scale as domesticated animals. They are often found around concentrated populations of dragons, relying on their larger brethren to ward away potential predators and leave scraps. As such, the majority of a pygmy’s diet is scavenged. Due to their tiny size, pygmies do not breed with larger varieties of dragons.

Yuie takes after her father's keen sense of direction and grace, and her mother's love of bouncing on the waves. She puts on a fantastic aerial display whenever anyone is around to see her dance. Rarely does she seem to rest from her fanciful maneuvers. Her "tempo" compared to Deejay is slower and flowing, and it would likely seem fitting to an orchestral composition inspired by the gentle rolling waves of the sea. No one has yet attempted to make such a performance to prove this however, due to the locations at which she performs her dances.
