Mistlet Pygmies thrive in humid environments and are most content when frolicking in the rain or fog. The cheerful demeanor they exhibit provides a remarkable contrast to their shadowy appearance, bringing joy in otherwise gloomy environments. Mistlets are an especially beautiful sight in long summer evenings, as their streak of vibrant scales catch the fading sunlight. They spend a great deal of their time foraging for edible roots and insects, and sometimes enjoy treats in the form of small fish or frogs.

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.

An energetic dragon, Agent Spin is a member of the Elite Beat Clan. He is also considered to be a "beginner" agent among the rest of the clan. He also has a hard time keeping up with the rhythm without a peculiar device wrapped around his head that Kim gave him. Despite this, he is also fairly good at dancing.

However, little is known about Spin. In fact, many wonder if Spin is his real name or if it's a codename used. That remains a secret between Spin, the EBA Clan, and Kim, and they're not going to be telling anyone anytime soon.
